HPS Silicone Air Intake Kit

The HPS Silicone Air Intake Kit is engineered as a direct replacement for the restrictive stock OEM rubber intake hose in 2008-2014 Infiniti G37 models with the 3.7L VQ37VHR engine. Constructed from high-temperature, 4-ply reinforced silicone, this hose is designed to withstand demanding conditions and meets or exceeds original equipment specifications, featuring a maximum temperature rating of 350°F. Installation of this post-MAF air intake hose requires no re-tuning or modifications and does not trigger a Check Engine Light (CEL). It delivers documented performance improvements, including dyno-proven gains of +6.8 wheel horsepower and +6.4 ft-lbs of torque, along with enhanced throttle response. The silicone construction also helps to reduce heat soak, ensuring the factory air box operates efficiently. Beyond performance enhancements, this HPS silicone intake kit serves as a crucial replacement part to resolve common issues such as rough idling and air vacuum leaks that often result from cracked, damaged, or collapsed OEM rubber hoses. The kit includes industrial-grade, 100% stainless steel heavy-duty t-bolt clamps and comes with an easy-to-follow installation manual with clear pictures. This product is not CARB exempt and is not legal for sale or use in California or on any pollution-controlled motor vehicle. It comes with a 2-year warranty.
