Chevrolet Silverado Performance Air Intake - Wehrli - 4in. - Flat Black - 2011-2016. Built for 6.6L Duramax LML trucks, this intake replaces restrictive factory parts to free airflow and sharpen response.

The WCFab 4in fabricated aluminum intake pipe pairs with a sealed air box and premium dry filter to feed your turbo with cooler, denser air drawn from the inner fender. Smooth, large-radius bends improve velocity while the hydrophobic pre-filter helps keep the MAF, turbo, and charge tract clean. Finished in durable flat black powder coat, it installs with basic hand tools using the included silicone boot, seals, and stainless T-bolt clamps—no tuning required. Expect crisper throttle and a more pronounced intake/turbo note under load.
