GMC Duramax Performance Air Intake - Wehrli - Semi-Gloss Black - 07-10. Purpose-built 4 in. intake and air box for 2007.5–2010 6.6L Duramax LMM, replacing restrictive factory parts for freer turbo flow.

Fabricated aluminum with an air box and dry filter draws cool air from the inner fender. The smooth 4 in. tract improves airflow and throttle response with a deeper turbo note. Silicone coupler, stainless T-bolt clamps, and included hardware provide a secure fit; the removable lid simplifies checks. A hydrophobic Outerwears pre-filter helps keep the MAF and turbo cleaner. Finished in durable semi-gloss black. Bolt-on, no tuning required. Made in the USA.
