Smashed Performance Intake Resonator Delete Plate for Chevy/GM Duramax LML 2011-2016 — Direct-Fit, Corrosion-Resistant Metal

Replace the stock intake resonator under your LML Duramax with a direct-fit Smashed Performance delete plate for a cleaner engine bay and crisper intake sound.

The Smashed Performance Intake Resonator Delete Plate is engineered specifically for Chevy/GM Duramax 6.6L LML engines from 2011–2016. It swaps into the factory intake elbow location without cutting, trimming, or permanent modification to the stock components. Supplied with all required hardware, this plate preserves proper sealing while removing the bulky factory resonator to deliver a more purposeful look and a livelier intake tone.

Will this fit my 2011–2016 LML 6.6L Duramax without modification?

Yes — the delete plate is laser-measured to match the factory intake elbow mounting points so installation is bolt-on and reversible. No cutting or extra adapters are needed.

• Designed for Chevy/GM Duramax LML 6.6L (model years 2011–2016).
• Direct-fit shape matches factory intake elbow flange.
• Includes hardware for a complete swap out of the stock resonator.

How will removing the resonator affect my truck’s sound and airflow?

Taking out the factory resonator reduces the muffling of intake noise, resulting in a more aggressive and noticeable intake tone under load and during throttle transitions. The delete plate maintains proper airflow sealing so performance remains consistent while producing a sportier acoustic character.

• Opens the intake path acoustically for a sharper intake note.
• Maintains sealed connection to prevent vacuum leaks.
• No forced airflow changes — preserves factory flow geometry.

What materials and finish does the delete plate use, and is it durable?

The delete plate is built from robust metal engineered to withstand engine-bay temperatures and vibration. Finishes are chosen to resist corrosion and keep the under-hood appearance clean for years of service.

• Sturdy metal construction for long-term durability.
• Corrosion-resistant finish suitable for engine environments.
• Precision-cut edges for proper seal and fitment.

How difficult is installation, and what tools or skills are required?

Installation is straightforward for anyone comfortable with basic hand tools and working in the engine bay. The kit includes the hardware you need; typical install time is short and does not require specialty tools.

• Simple bolt-on swap using included hardware.
• Requires basic hand tools and moderate mechanical familiarity.
• Reversible — original resonator can be reinstalled if desired.

Who is this for: The Smashed Performance Intake Resonator Delete Plate is aimed at Duramax LML owners who want a tidier engine bay and a more pronounced intake sound without altering intake components permanently. It suits truck enthusiasts who prefer a factory-style installation, DIY mechanics seeking a quick bolt-on upgrade, and anyone wanting a durable, reversible solution to remove the stock resonator while keeping a sealed, reliable intake connection. The product ships ready-to-install with hardware and is ideal for cosmetic enhancement and acoustic preference upgrades while retaining factory fitment.
