I got my mishimoto installed about a month ago and no problems with fitment or anything. Just make sure you get the right one because the 350z and G35 are different. The mishimoto comes with it's own high bar cap.

Some of the early sedans have a different fitment I believe...as the person above had some fitment problems.

You can find some threads about the Mizu radiator at my350z.com. One guy swapped out his Mishimoto for a Mizu too.

I wouldn't either. If it doesn't for some reason just grab a Nismo one.

I just don't wanna take any chances with fitment issues on the Mishimoto. This car is my daily and the last thing I want is to run into problems during install that require me to fab something and waste time trying to get back on the road.

I'm most likely gonna go with Koyo, unless there are some compelling reasons for something superior, which I have not yet seen. Just trying to sort out the radiator cap issue so I have everything I need for the install prior to beginning.

Is there anyone else out there running the Koyo radiator with a non-Koyo radiator cap?

BTW, thank you Lone Wolf for all your input. You've been very helpful in making my decision easier.

I didn't have any critical fitment issues with the Mishimoto to the point where it didn't fit or anything...Just it's not a perfect fitment like advertised.

On the first radiator it didn't go down all the way into the mounting holes because it hits part of the core support. Also, the fan shroud couldn't be installed because the mounting holes for that didn't line up with the radiator. I had to use zip ties to hold the top part of the stock intake (rather than the plastic push clips) because the radiator sits so high that it almost touches the top of the core support. Other than that, it was OK.

On the second radiator I had most of the same issues, except this one sat down lower in the core support. This created a new problem though: The radiator cap hits the top of the core support, so I have to push down on it in order to screw on or screw off the cap. Luckily I didn't have to cut anything here like others. Also, on the new one the top mounting holes are off some...The right one should be shifted about 1/2" to the left.

I'm running a ARC radiator cap without issue on my Koyo.

Subscribed. Helpful thread almost pulled the trigger on mishimotos.. This most definitely swayed my decission to KOYO or MIZU.. Never heard of MIZU, but doing my research on it now!! Thanks for sharing experiences.

AT has transmission cooler lines that run through the radiator. If you buy a radiator design for a MT, it will not have the fittings for this.

okay so I've been researching radiators.... i really wanted the Mishimoto radiator/fan shroud combo but heard that mishimoto has fitment issues.... so I've been looking into KOYO radiators.... heres what I've found....


KOYO ALUMINUM RACING RADIATOR INFINITI G35 03-07 COUPE 03-06 SEDAN VQ35DE V2588

it says "Fits Manual Transmissions Only (for Automatic Transmission this will fit but External Transmission cooler needed)."

1) what does that mean??^^

2) does KOYO make radiators for A/T?

3) dont we have OEM transmission coolers already?

4) what kind of fan shroud can i get?

5) how much modification needs to be don't if KOYO does not make one for 5 A/T?

6) does this mean i have to buy a transmission cooler as well??

HELP!!
