Description

The Wehrli Custom Fabrication L5P 4-inch High Flow Cast Aluminum Turbo Intake Horn, MPN WCF100775-CT, is designed for 2017-2026 Chevrolet Silverado or GMC 2500/3500 HD trucks equipped with the 6.6L Duramax Diesel (L5P/L5D engine). It replaces the restrictive OEM plastic turbo mouthpiece with a true 4" turbo inlet with optimized airflow for improved engine performance and throttle response. This upgrade provides 25% greater flow area than OEM at the compressor inlet and 27% better flow than stock counterparts. It is compatible with OEM and aftermarket cold air systems and stock/OEM-style aftermarket drop-in turbochargers.
