Utheer Grill Replacement Kit for Weber Spirit 300 Series 2013–2017 — Porcelain Flavorizer Bars & Stainless Burners

Utheer replacement kit supplies heavy-duty porcelain-enamel flavorizer bars, stainless-steel burner tubes, and an ignitor wire crafted to fit Weber Spirit and Spirit II 300 Series (2013–2017) grills.

If your Spirit 300 series grill shows uneven heat, flaking heat shields, or a faulty ignitor, this Utheer kit offers a full under-burner refresh built to match the front-mounted control-panel models listed by Weber. The kit includes five porcelain-enamel flavorizer bars, a set of three main stainless-steel burner tubes plus a crossover tube, and an ignitor wire—assembled to restore even heat distribution, protect burners from drippings, and simplify relighting.

Which Weber models does this Utheer kit fit?

This kit is engineered for Weber Spirit 300 series grills made between 2013 and 2017 that have front-mounted (up-front) control panels. It matches specific model numbers from 2013–2015 and later 2015 variants listed by Weber.

• Compatible with Weber E-310, E-320, E-330 and Spirit S-310, S-320, S-330 variants noted in the product spec.
• Designed for models with up-front control panels (front-mounted knobs).
• Check your grill’s model plate or owner’s manual to confirm match before purchase.

How are the dimensions and materials suited for heavy use?

Utheer provides precise dimensions and heavier-gauge materials to withstand frequent grilling. The flavorizer bars are porcelain-enamel coated for drip protection and the burner tubes are stainless steel with added thickness for durability and consistent heat.

• Flavorizer bar size: 15.3" L × 2.6" W × 2.5" H for reliable coverage and fit.
• Main burner lengths: two at 18" and a center at 17.75"; crossover tube 15.25" for proper alignment.
• Materials: porcelain-enamel bars plus thicker stainless-steel burners for corrosion and heat resistance.

What improvements can I expect after installing this kit?

Replacing worn flavorizer bars and burners restores more even heat and reduces flare-ups by directing drippings away from open flame. The heavier materials also slow down corrosion and extend the service life compared with thin, worn originals.

• Better heat distribution and fewer cold spots on the cooking grate.
• Reduced flare-ups thanks to intact flavorizer shields redirecting drips.
• Longer-lasting components with improved oxidation and corrosion resistance.

How easy is installation and upkeep?

The kit ships with an installation manual and is intended for straightforward replacement of existing parts. Routine cleaning keeps the porcelain-enamel bars looking and performing their best.

• Includes step-by-step installation manual and ignitor wire for relighting convenience.
• Wipe excess grease, preheat and brush to remove residue; dry thoroughly before storage.
• No special tools required for most installations; basic hand tools usually suffice.

Who is this for: Homeowners and backyard grill enthusiasts who own a Weber Spirit or Spirit II 300 Series (2013–2017) with up-front controls and want a durable, cost-effective replacement for corroded flavorizer bars, worn burners, or a failing ignitor. This kit suits anyone who prefers heavy-gauge components that improve heat consistency and lower the need for frequent part swaps.
