Fantastic upgrade for my 2005 G35. I now trust that my vehicle will run strong and not overheat. The Koyo radiator is really nicely made, and everything lines up well for perfect fit when installing. This was my first purchase at ConceptZ, and they were great to work with to keep my car going.

Super easy to install, running even cooler now. Perfect fit, looks great and works wonders!

Definitely worth it coming from a stock radiator that cracked by the upper radiator hose. I have a 05 6mt G35 Sedan and it warms up allot faster now that I have this KOYO Radiator instead of the OEM radiator.
