AIRFLOW - STAGE 2 LLY HSP Diesel 2007.5-2010 Chevrolet / GMC Max Air Flow Bundle - 483-HSP

*Description:*

This kit allows both you and your engine to breathe easy, featuring a mandrel-bent 4.5-inch intake tube for massive airflow gains. HSP's signature heat shield box eliminates unwanted hot air from entering the cold air intake, ensuring cooler, denser air for optimal engine performance.

Maintaining cooler intake air temperatures is crucial, as every 1-degree increase can result in a loss of approximately 3hp. This kit also includes HSP's high-flow turbo mouthpiece, which enhances airflow by rerouting the factory PCV system and removing the factory resonator box, preventing engine oil from contaminating the turbo and intake system (PCV re-route sold separately, see 003-1-HSP).

Additionally, the kit features 3-inch mandrel-bent hot and cold side tubes paired with an easy-to-install two-piece Y-bridge. The race-proven 5-layer silicone boots ensure a durable fit that won't let you down. The factory hot side intercooler tube, which is 2.25 inches with a 90-degree boot, is prone to failure. HSP's innovative routing solution runs the hot side tube directly into the intercooler, resulting in lower temperatures, improved airflow, and added clearance in tight spaces.

The 3-inch cold side tube ensures your engine receives all the air it needs for optimal performance. The two-piece Y-bridge provides a leak-free seal, ensuring a reliable and hassle-free installation. Also included is a 2-inch passenger-side up-pipe featuring .120 inch tubing and top-of-the-line bellows. The factory up-pipe often fails at the riser due to excessive heat and pressure, and this upgrade addresses that issue effectively.

This kit is constructed from high-quality materials to withstand the rigors of the engine bay, providing reliable performance over the long term. The components are finished in a durable custom powder coat, adding an extra layer of protection and giving your engine bay a sleek look.
