Meets or exceeds OEM quality
No issues installing, whatsoever. Can’t tell the difference between the factory original and this as it is an exact look and fit.

Does not match oem for 07 350Z
The base is thinner so the oem bolts are too long. It should be noted in the item description. I had to wait another day to go buy some shorter bolts and waste another trip to the parts store. I did not have anything to use as spacers to make the original ones work. Very unsatisfied

Be aware of the possibility that this does NOT fit …
Be aware of the possibility that this does NOT fit (EX 2008) exactly but you will have to use/modify with different spacers/bolts. I’ve checked carefully with other on line auto part sellers and they too list this exact same part and part numbers thermo. So maybe Nissan has change this part afterall. Once you retro fit this it seems to function properly. 3 stars for the initial shock of “damn I ordered the wrong part” to “hey this can indeed fit”

doesn’t fit infinity g35.
Everything bolts up fine. The problem is that you have two hoses (large radiator and smaller heater hose) on the infiniti. This thermostat housing doesn’t have output for second hose.

Definitely fits the VQ35HR, but the base is slimmer
The thermostat fits and works just fine, but the base thickness is less than OEM so you will probably need either some spacers or 3 new bolts. No big deal, but keep it in mind. Functionality is flawless, it opens when it’s supposed to open. No idea regarding longevity, will update if I consider it less than ideal.

Excellent Fit
I ordered this part to replace a worn out thermostat on a 2000 Nissan Maxima SE. It was an exact fit and installation was easy. The gasket does contain some adhesive to allow you to stick it to the thermostat prior to installation. I do recommend that you still use gasket sealant upon installation.

don’t trust their model fit
They lie. It says it fits 2010 m35. It is approx 3/8:” thinner than oem. I sheared the bolt into the engine while torqing down. Nice. You can refund my money – How about my time to remove and replace the bolt?
