I had a mad overheating problem with my '06 350z and had 2 different mechanics "fix" said problem. After hundreds of dollars and a still overheating car, I decided to buy this product and install it with a few friends over a weekend. Why didn't I do this first. It, along with the "Mishimoto Silicone Hose Kit Black 03-06 Nissan 350Z" and the "Mishimoto Racing Thermostat Nissan 350Z 03-06 Z33", I now have a car that only heats up to the lowest operating temperature point. Worth every cent.

Fits into my 2006 350z. A little bigger, so it takes some persuasion to install.
