Overview

By positioning the filter outside the engine compartment, it ensures the coolest possible air inlet temperatures, leading to a more powerful combustion. The system's inlet pipe is tuned to harmonize with the engine's resonance, pushing more air into the cylinders for maximum gains across the RPM range.

Show original supplier description

This system positions the air filter outside the engine bay, ensuring it captures the coldest possible air. Cooler air contains more oxygen, which translates to a more efficient combustion process, resulting in increased horsepower and torque. The intake pipe's specific length and diameter are meticulously tuned to work with your engine's natural resonance, effectively acting as an air pump to force more air into the cylinders and maximize power gains throughout the entire RPM range. Constructed from lightweight T-304 aluminum with a polished finish and a black powder-coated exterior, this intake kit is built for durability and performance. Installation is straightforward, requiring only simple tools, and all necessary mounting accessories are included, meaning no additional parts are needed. This cold air intake kit is specifically designed for the 2008-2017 Nissan 370Z and the 2008-2013 Infiniti G37, both equipped with the 3.7L V6 engine. It is stated to improve throttle response, increase horsepower by 7-10%, and boost torque by 6-8%.
