Description

The Stillen air intake hose kit, part number 87-68426, is engineered to replace the restrictive stock OEM rubber intake hose on your 2008-2014 Infiniti G37 3.7L VQ37VHR. Constructed from high-temperature, 4-ply reinforced silicone, this kit meets or exceeds OE specifications with a maximum temperature rating of 350°F. This air intake hose kit delivers dyno-proven performance gains, increasing horsepower by +6.8 whp and torque by +6.4 ft/lbs, while also improving throttle response. It integrates with the factory air box to direct cool air to the engine, maximizing cooling efficiency and reducing heat soak. The kit includes industrial-grade, 100% stainless steel heavy-duty t-bolt clamps for secure installation. Beyond performance enhancements, this HPS silicone air intake hose kit serves as a crucial replacement part to address and prevent common issues such as bad idling and air vacuum leaks that arise from cracked, damaged, or collapsed OEM rubber hoses. Installation is straightforward with a provided step-by-step manual, and no modifications are required. It does not trigger a CEL light and is compatible with the OEM hose. Please note: This product is not CARB exempt and is not legal for sale or use in California or on any pollution-controlled motor vehicle.
