For the 370z, driver side pipe will need to be cut to make it fit. I just used a hand saw to cut about 1/2 an inch off on the filter side, not the throttle body side. I just measured against the stock pipe. It will be a tight fit. My low-end torque dropped, but mid and high-end slightly improved. I hope this helps. My next purchase might be k&n drop-in filters and see if that improves my low-end. 4/5 because I needed to cut to make it fit and was not drop in. Difficulty 3/10.
