HPS Silicone Air Intake Kit

The HPS Silicone Air Intake Kit Post MAF Hose (part number 87-68426) is engineered as a direct replacement for the restrictive stock OEM rubber intake tube in 2008-2014 Infiniti G37 3.7L VQ37VHR vehicles. Crafted from high-temperature, 4-ply reinforced silicone, this hose is built to withstand demanding conditions and meets or exceeds Original Equipment specifications, boasting a maximum temperature rating of 350F. This performance-oriented intake hose optimizes airflow, leading to noticeable improvements in engine performance. It delivers dyno-proven gains of +6.8 whp and +6.4 ft/lbs of torque, coupled with enhanced throttle response. Beyond power increases, the HPS silicone hose also contributes to reducing heat soak, ensuring the airbox functions efficiently, and serves as a crucial replacement for addressing common issues such as poor idling and air vacuum leaks that arise from cracked or deteriorated factory rubber hoses. The kit includes industrial-grade, 100% stainless steel t-bolt clamps for secure mounting. Importantly, no re-tuning or vehicle modifications are necessary for installation, and it will not trigger a Check Engine Light. The product comes with a 2-year warranty. However, it is important to note that this product is not CARB exempt and is not legal for sale or use in California or on any pollution-controlled motor vehicle.
