The radiator is great and would recommend it to G35 drivers. One thing to note is that its is thicker than the stock so had to get a flex hose with coil springs inside because I lost room for the original bottom radiator hose (the long hose).
Fan was also pushed back closer to engine due to the thick radiator. No doubts about the radiator because its definitely the best for performance racing and daily drivers.
FYI: Fan went out for a week and the radiator still kept the engine temperature under average. Waiting on my new K-Metal fan to arrive. Good luck.
Don’t cheap out just get this radiator the other ones don’t have a automatic transmission cooler built in like this one. Pretty easy install even the stock fans fit after install .
No comparison to the cheap stock radiator. Beautiful welds and an all aluminum design (No more plastic top and bottom). All the hoses and cap are in the right place., unlike others I saw. A no brainer for performance driving or just getting stuck in LA traffic. It took a little more finesse to get it in but well worth it.
