Chevrolet Duramax LB7 Performance Air Intake by Wehrli (WCFab) - 4 in with Air Box, Bengal Silver, for 2001-2004 trucks. High-flow aluminum system that replaces the stock plastic intake.

The 4 in tube uses smooth bends to increase air velocity to the turbo, and the enclosed box draws cool air from the inner fender for steadier temps and a more pronounced turbo sound under throttle. A dry filter and removable lid simplify service. Silicone couplers, seals, and stainless T-bolt clamps ensure a secure fit. No tuning required; installs with basic hand tools.

Features

• 4 in aluminum intake pipe with air box and lid
• Bengal Silver powder coat
• Dry filter with hydrophobic pre-filter cover
• Direct bolt-on for 2001-2004 GM 6.6L Duramax LB7
