Description

The HPS Silicone Air Intake Kit (part number 87-68426) is engineered to replace the restrictive OEM rubber air intake hose in your 2008-2014 Infiniti G37 3.7L VQ37VHR. This direct-fit upgrade optimizes airflow, delivering dyno-proven performance gains of up to +6.8 whp and +6.4 ft/lbs of torque, while also enhancing throttle response. The HPS silicone intake kit helps reduce heat soak by integrating with the factory air box and fresh air scoop, ensuring cool air reaches the engine for optimal cooling. It also serves as a crucial replacement part to fix common issues like bad idling and air vacuum leaks caused by cracked or damaged OEM rubber hoses. The kit includes HPS Performance industrial-grade, 100% stainless steel heavy-duty t-bolt clamps for secure installation. No re-tuning or modifications are required, and it will not trigger a Check Engine Light (CEL). The installation process is straightforward, with an easy-to-follow step-by-step manual provided. This product is backed by a 2-year warranty. Please note that this product is not CARB exempt and is unavailable for purchase or use in California.
