Description + Fitment
The WCFab LB7 4 in. High Flow Cast Aluminum Turbo Intake Horn for 2001-2004 Chevrolet Silverado or GMC 2500 / 3500 HD trucks equipped with the 6.6L Duramax Diesel is the largest and highest flowing turbo inlet on the market. Replaces the restrictive OEM turbo mouthpiece to provide increased airflow to your turbocharger for improved engine performance and throttle response. Compatible with factory IHI Turbo or upgraded drop in IHI Turbos and aftermarket intakes. Great upgrade offering quicker spool up and more HP! Max-effort tuned trucks can see 10-15 HP gains while applications with upgraded turbochargers can experience as much as 20 HP improvements. Custom powder coated in the color of your choice. Made in USA! Pair it with our 4" Cold Air Intake Kits and Stage 1 High Flow Bundle Kits along with custom performance tuning and drop in performance turbochargers for maximum performance gains. - - NOT COMPATIBLE WITH OEM INTAKE - - Fitment Note: Works with performance aftermarket intake systems utilizing a 4" Boot Connection with bead roll, like our 4" Intake Kits. Will your 3rd party intake be compatible? If the rubber / silicone connection of your current air intake is molded into the intake pipe / is not removable, that intake will not work / fit with this product. - - Supersedes WCF100342
