Wehrli 17-24 Duramax L5P High Flow Intake Horn - Gloss Black

The Wehrli High Flow Intake Horn in Gloss Black is designed to replace the restrictive OEM plastic turbo mouthpiece on 2017-2024 Chevrolet Silverado and GMC 2500/3500 HD trucks equipped with the 6.6L Duramax Diesel (L5P) engine. This upgrade delivers increased airflow to the turbocharger, resulting in improved engine performance and throttle response. It features robust CNC Machined Cast Aluminum Construction, a custom powder-coated Gloss Black finish, and offers a 25% greater flow area than the OEM part at the compressor inlet. It also includes a #10 ORB threaded billet aluminum hose barb for PCV connection and a true 4" inlet turbo intake with a strategically designed anti-surge face. This is a straightforward, bolt-on upgrade that requires no additional tuning or modifications and is compatible with both stock and aftermarket cold air intake systems.
