Equipping an aftermarket cold air intake is often one of the most cost effective and easiest way to see good horse power gains. Our Nissan 370Z cold air intake systems are perfect for just about any Z car enthusiast. With our Nissan 370Z cold air intake you will see great horsepower gains and improved throttle response as well as improved fuel economy. Our 370Z cold air intake is also a ETI (electronically tuned intake) system so they run a much larger diameter pipe without throwing any check engine lights.
