Weber Spirit · Parts Guide
Flavorizer bars are the #1 most-commonly-replaced part on Weber Spirit gas grills. Unlike burner tubes that last 8-12 years, flavorizer bars fail faster — porcelain-coated bars in 3-5 years, stainless steel bars in 7-10 years. They're directly exposed to grease drippings, flare-ups, and daily temperature cycling. Replacement is straightforward ($30-85 depending on OEM vs aftermarket, 10-minute installation) but ordering the wrong generation's bars is the most common mistake. This guide walks you through identifying your specific Spirit first, then connects you to the exact flavorizer bars for your grill.
This page is a Spirit-specific deep dive on flavorizer bars. For cross-model flavorizer bar comparisons across Weber's full lineup (Spirit, Genesis, Summit), see our Weber Flavorizer Bars Guide. For Spirit burner tube replacement, see our companion Weber Spirit Burner Tubes guide. For all Spirit replacement parts, see the Weber Spirit Grill Parts hub.
The Basics
The angled metal strips sitting above your burners aren't decorative — they're a patented Weber innovation that makes Weber gas grills cook the way they do.
Flavorizer bars are the angled V-shaped metal strips mounted directly above the burner tubes, below the cooking grates. They have three critical functions:
The angled bars deflect grease drippings away from the gas burner ports underneath. Without flavorizer bars, grease would drip directly into the burner tubes, clogging the gas ports. This protection extends burner tube lifespan from 4-6 years to 10-15 years on properly-maintained grills.
When grease drippings hit the hot flavorizer bars, they vaporize and smoke — producing a smoky flavor that recirculates up through the food. This is what makes Weber gas grilling taste meaningfully different from cheaper gas grills that use heat tents or rock grates.
Flavorizer bars spread heat across the full cooking surface rather than leaving hot spots directly above the burners. The angled design redirects direct flame upward at a 45-degree angle, creating a more uniform temperature across the grate.
When flavorizer bars fail (rust-through, warping, splitting), all three functions degrade simultaneously. Your burners get dirtier faster, food loses that distinctive Weber flavor, and temperature distribution becomes uneven. Time to replace.
Diagnosis
Knowing when replacement is needed helps you catch problems before they affect cooking performance.
The #1 most common sign. Porcelain-coated bars develop rust once the coating chips; stainless bars develop rust at metal fatigue points. Once rust starts, it accelerates. Minor surface rust is fine; pitting or flaking is replacement territory.
High-heat cycles cause metal fatigue. Visibly bent, split, or wavy flavorizer bars don't distribute heat properly and can drop grease directly onto burner tubes. Any visible warping = replacement needed within 1-2 cooking seasons.
If you notice uneven flame patterns, delayed ignition, or yellow spots on burner tubes after cooking, your flavorizer bars may have holes or gaps letting grease through. Damaged bars = damaged burners shortly after.
If your grilled food has started tasting more "gas grill" and less "Weber smoky" compared to when the grill was new, flavorizer bars may have lost their vaporization performance. Usually paired with visible damage but sometimes happens before other symptoms appear.
Typical Spirit flavorizer bar lifespan: Porcelain-coated bars 3-5 years; stainless steel bars 7-10 years. Bars exposed to rain last less; covered grills last longer. Many Spirit owners replace flavorizer bars 2-3 times during the grill's overall 15-20 year lifespan — each replacement restores original cooking performance.
Step 1
Flavorizer bar dimensions vary across Spirit generations. Ordering the wrong generation's bars is the most common mistake. Identify your grill here before shopping.

Common models
Quick identification rule: count your current flavorizer bars before ordering. 5 bars, 15-1/4" long = Spirit 300 Series or Spirit II 300 (2013+). 5 bars, 22-1/2" long = Legacy Spirit with side controls (pre-2012). 3 bars, 15-1/4" long = Spirit 200 or Spirit II 200 (2-burner models). When in doubt, measure one existing bar with a tape measure — the length difference between generations is obvious (15 vs 22 inches is not subtle).
Most Common Tier
The Spirit II 300 Series plus the earlier 2013-2017 Spirit 300 Series with front controls use IDENTICAL flavorizer bars (backward compatible). This covers the largest segment of current Spirit owners.
Official Weber stainless flavorizer bars for Spirit 300 Series (2013-2017) and Spirit II 300 Series (2017+). Set of 5 bars, each 15-1/4" long x 2-1/2" wide x 2-1/2" tall. 430-grade stainless. Lasts 7-10 years.
Official Weber porcelain-enameled flavorizer bars for Spirit 300 Series (2013-2017) and Spirit II 300 Series (2017+). Set of 5 bars, same 15-1/4" dimensions as stainless. Black porcelain coating. 3-5 year lifespan.
304-grade stainless aftermarket bars for Spirit 300 / Spirit II 300. Set of 5 bars matching OEM dimensions (15-1/4"). Widely available from QuliMetal, Hongso, Uniflasy, PETKAO. Some have ventilation holes for flame efficiency.
2-Burner Spirit
Spirit II 200 Series uses the same 15-1/4" flavorizer bar dimensions as the 300 Series, but only 3 bars per grill instead of 5. Ordering by model count (2-burner vs 3-burner) matters more than ordering by part number.
Official Weber stainless flavorizer bars for Spirit 200 Series (2013-2017) and Spirit II 200 Series (2017+). Set of 3 bars, each 15-1/4" long. Fits 2-burner Spirit models: E-210, S-210, E-215, S-215, E-220, S-220, E-225, S-225.
Porcelain-enameled flavorizer bars for Spirit 200 Series. Set of 3 bars, 15-1/4" x 2-1/2" x 2-1/2" dimensions. Less expensive than stainless; shorter lifespan (3-5 years vs 7-10 for stainless).
304-stainless aftermarket flavorizer bars for Spirit 200 / Spirit II 200. Set of 3 bars matching OEM dimensions. Brands include Grillpartsreplacement, QuliMetal, Hongso.
Important ordering note for 2-burner Spirit owners: Some sellers list "Spirit II 310 flavorizer bars" and "Spirit II 210 flavorizer bars" separately when they're actually identical dimensions in different quantities (5 vs 3). Buy by count matching your grill — 3 bars for 2-burner models, 5 bars for 3-burner models. If in doubt, count your existing bars before ordering.
Pre-2012 Side Controls
Pre-2012 Weber Spirit grills with side-mounted control knobs use DIFFERENT flavorizer bars than current Spirit models. These are 22-1/2" long (vs 15-1/4" on current Spirit II). Wrong parts won't fit properly.
Official Weber stainless flavorizer bars for Spirit 500, 700, Weber 900, and 2007-2012 Spirit E/SP/EP-310/320 with side controls. Also fits Genesis Silver/Gold B/C (2002-2012). Set of 5 bars, 22-1/2" long x 2-1/4" wide x 2-3/8" tall.
Porcelain-enameled flavorizer bars for pre-2012 Spirit with side controls. Set of 5 bars, same 22-1/2" dimensions. Compatible with Spirit 300/700, Weber 900, and most Genesis Silver/Gold/Platinum grills from that era.
304-stainless aftermarket flavorizer bars for 22-1/2" legacy Spirit models. Set of 5 bars matching OEM dimensions. Availability is more limited than current Spirit II parts; check Amazon reviews before ordering.
Additional legacy Spirit identifier: if your grill has silver A variant (Part #65902) or was originally sold around 2000-2001, double-check the dimensions before ordering — some very early Spirit models used slightly different flavorizer bar specifications. Contact Weber at 1-800-446-1071 with your serial number if you can't verify. Very rarely, the Weber Silver A used unique-length flavorizer bars not listed above.
Material Choice
Weber makes flavorizer bars in two materials at different price points. Here's the honest comparison for Spirit owners.
430-grade stainless construction. The longer-lasting option with 7-10 year lifespan vs 3-5 years for porcelain. Won't chip or flake. Better heat retention. Premium material for premium longevity.
Buy stainless when:
Black porcelain enamel coating over steel. Non-stick surface prevents grease buildup. 15-25% cheaper than stainless. Coating chips over time, exposing steel to rust. 3-5 year lifespan.
Buy porcelain when:
Our take: stainless steel wins for 80% of Spirit owners. The $15-25 premium (OEM pricing) or $10 premium (aftermarket pricing) pays for itself in the first replacement cycle you avoid. Most Spirit owners who switched from porcelain to stainless after their first replacement don't go back.
Buying Strategy
For flavorizer bars specifically, aftermarket is often the smart choice. Here's when OEM is worth the premium.
Manufactured by Weber to exact factory specifications. Perfect fit. Preserves warranty on grills under Weber's 10-year coverage. Direct customer service for installation questions.
Buy OEM when:
Third-party manufacturers (QuliMetal, Hongso, Uniflasy, PETKAO, Grillpartsreplacement) make bars dimensionally compatible with Weber Spirit part numbers. 40-60% cheaper than OEM. Some include ventilation hole improvements.
Buy aftermarket when:
Our recommendation for flavorizer bars specifically: aftermarket is usually the smart choice. Flavorizer bars aren't gas-carrying parts (unlike burner tubes where fit precision matters more), so minor fit variations have lower stakes. Quality aftermarket bars match OEM performance at significantly lower cost. Save the OEM premium for burner tubes and igniters where it matters more. For Spirit II 300 Series flavorizer bars: aftermarket set of 5 for $30-55 is excellent value.
DIY Installation
Easiest Weber Spirit repair — no tools required, no gas disconnection needed, takes 10 minutes total.
Turn off gas and let grill cool completely
Safety first. Turn off gas at the LP tank or NG supply. Let the grill cool fully before handling flavorizer bars — they reach 500°F+ during cooking and retain heat for 30-60 minutes after turn-off. Never attempt this while the grill is still warm.
Remove cooking grates
Lift all cooking grates out of the grill. Set aside on a clean surface. Cleaning them while you're at it is a good habit.
Lift out old flavorizer bars
The old bars simply lift out of their support brackets. No screws, no hardware, no tools needed. If bars are stuck to support brackets due to grease buildup, wiggle gently to loosen. Dispose of old bars properly — they may have grease residue.
Clean the support brackets
With old bars removed, inspect the support brackets underneath. Wipe away grease buildup, debris, or rust with a damp cloth or paper towel. Clean brackets allow new bars to seat properly and evenly.
Install new flavorizer bars
Place new bars into the support brackets, ensuring proper orientation — the angled edge faces DOWN (peaked side up). Each bar should sit flat in its slot. If bars rock or wobble, they're not seated properly — lift out and reseat.
Reinstall cooking grates
Place grates back on top of the flavorizer bars. Verify grates sit flat and don't rock on uneven bars.
Test light the grill
Reconnect gas. Light each burner individually. Check for uniform blue flame and even heat distribution across the cooking surface. Close the lid and heat the grill to 400°F for 10-15 minutes to burn off any packaging residue from new bars before cooking food.
Avoid These
Mistakes that waste money on wrong parts or shorten the lifespan of new bars.
The most common mistake. Legacy Spirit (2007-2012 side controls) uses 22-1/2" bars. Current Spirit II (2013+) uses 15-1/4" bars. These are NOT interchangeable — the length difference is obvious. Always verify your grill's generation before ordering. Count existing bars: 5 bars at 22" = legacy; 5 bars at 15" = Spirit II 300; 3 bars at 15" = Spirit II 200.
Spirit 300 Series (3-burner) takes 5 flavorizer bars. Spirit 200 Series (2-burner) takes 3 bars. Some sellers don't clearly indicate quantity in listings. Count your existing bars or burners: 3 burners = 5 bars; 2 burners = 3 bars. Ordering a "Spirit 300 set" for a Spirit 200 grill leaves you with 2 extra bars.
Traditional wire grill brushes can shed metal bristles during cleaning. Bristles stuck to new flavorizer bars can fall into burner tubes, creating hot spots and uneven flame patterns. Switch to bristle-free brushes (Grill Rescue, GrillArt, nylon) for cleaning any grill surfaces near new flavorizer bars.
Flavorizer bars have an angled V-shape with the peak facing UP and flat edges facing DOWN. Installing bars upside down (flat edge up, peak down) gives you all the downsides (grease goes straight to burners) with none of the benefits (no vaporization for flavor). Sounds obvious but it happens — verify orientation before reinstalling grates.
If 2 of your 5 bars look badly rusted and 3 look "okay," replace all 5. Mixing old and new bars means the cookbox performance will be uneven AND the older bars will fail soon anyway, requiring another repair within 12-18 months. Full replacement saves labor time and ensures consistent performance.
