Enhance your Infiniti FX37’s performance with the Injen SP1911P cold air intake system. Crafted from polished 6061-T6 aluminum, this short ram intake features dual tuned tubing designed to optimize airflow and boost horsepower by up to 16 HP and torque by 15 ft-lbs. The smooth, unrestricted path provided by the engineered piping ensures maximum efficiency, helping your engine breathe easier and deliver more power during acceleration. This system is specifically designed for a direct fit on Infiniti FX35 and FX37 models from 2009 to 2013, as well as select Toyota Tundra trucks from 2021, making it a versatile upgrade for compatible vehicles.
Injen’s patented MegaRam (MR) Technology and Air Fusion Technology are integrated into this system, providing a tuned intake that maintains a safe air-fuel ratio while maximizing performance gains. The included fully serviceable SuperNano-Web dry air filter offers increased surface area for superior airflow and filtration, ensuring your engine receives clean air at all times. The system also features dual heat shields tailored specifically for this application, helping to prevent heat soak and maintain optimal intake temperatures. The aggressive sound produced under full throttle adds a sporty character to your vehicle’s exhaust note, making every drive more exhilarating.
Manufactured in Pomona, California, this intake system is built to last and backed by Injen’s limited lifetime warranty. It is available in multiple finishes for customization and easy integration into your vehicle’s engine bay. Please note that this product is not CARB exempt and is intended for off-road or racing use only. Installation requires no additional tuning, making it a straightforward upgrade for enthusiasts seeking increased horsepower, improved throttle response, and a more commanding engine tone.
