GMC Sierra Performance Air Intake - Wehrli - 4in Intake Kit - Illusion Blueberry - 04–05. Built for 2004.5–2005 GMC Sierra 6.6L Duramax LLY, this high-flow intake and air box replace restrictive factory parts for sharper response.

Fabricated from aluminum with a true 4-inch tube and smooth bends, it draws cooler air from the inner fender to help reduce intake temps. The dry filter and hydrophobic pre-filter help protect the MAF and turbo, and the removable lid makes inspections quick. Quality silicone coupler, seals, and stainless T-bolt clamps provide a solid, bolt-on install. Finished in Illusion Blueberry powder coat. Made in the USA.
