The GMC 3500 HD Performance Air Intake by Wehrli - 4in High Flow Intake Horn in Sparkle Bomber Orange is designed specifically for the 2001-2004 Duramax LB7 engines. This precision CNC machined cast aluminum intake horn is not just a stylish addition to your engine bay, but a significant performance upgrade that optimizes airflow to your turbocharger, thereby enhancing engine performance and responsiveness.

This high-flow intake horn replaces the restrictive OEM turbo mouthpiece, allowing for increased airflow and improved throttle response. Compatible with both the factory IHI Turbo and upgraded drop-in IHI Turbos, this upgrade is crafted to boost your truck's performance, yielding gains of 10-15 HP for max-effort tuned trucks and up to 20 HP when paired with upgraded turbochargers. The custom powder-coated finish in Sparkle Bomber Orange offers a unique aesthetic appeal, while the option to pair with our 4" Cold Air Intake Kits and Stage 1 High Flow Bundle Kits ensures maximum performance gains.
