MITZONE Upgrade Aluminum Valve Covers Left and Right Compatible with 2003-2008 Nissan 350Z Infiniti FX35 G35 M35 VQ35DE 3.5L Part # 13264AM600 13264AM610

I received my aluminum valve covers with all hardware and gaskets. They look amazing and can’t wait to throw them on my 350z. Packing was great and everything seemed in great shape.

Fit perfect 05 Infiniti g35x

Install went smooth.. gaskets are working to fix oil leak it's been about 700 miles and no leaks so far.. my only complaint is the paint finish although I love the color seems to be a little thin.. where these need to be installed is a tight fit and any little bump scratches the paint off the valve covers which is frustrating because the reason you get the color is to show it off.. It's not worth taking off and redoing them but just small frustration. So be as careful as you can but understand very likely you will scratch the paint and with have to live with it or try to touch it up later. That why 4 stars not 5.

I don't write many reviews, but I had to write this one. I am an 18 year Nissan Master Technician and the OEM valve covers for 350Zs, FX35s, etc are super uber expensive. These are a GREAT VALUE. The gaskets came pre-installed into the valve cover grooves. Fit and finish seemed fine. And the gasket was "squishy" and "Flexible" like the OEM gaskets.Upon installation, I lubricated the tube seals with WD40 to aid in them fitting over the spark plug tubes. They worked perfectly. I think some of the negative reviews about this product are due to installation issues and not taking care to not roll the seals/gaskets or not paying attention to the tube seals not getting cut by the spark plug tubes. I highly recommend them. Just be sure to also purchase the PCV cross-over hose that goes between both valve covers as yours will be dry-rotted and hard as plastic.

Been running these valve covers on my G for about one year. Out of the box, you have to take off the baffles and clean out metal shavings. Bad overspray on the inside of the valve covers and in the bolt holes. All bolts were torqued to spec and in sequence, but the driver side valve cover eventually warped. Also, the threads for the coil pack bolt holes are weak, the threads broke when tightening the bolt to torque spec after doing some check-up on the car. They are cheap, but the quality is poor and these are not worth the buy.

The media could not be loaded. 3/5 stars because they look awesome & come with all the hardware ie bolts, new oil cap, pvc valve/ hose, and gaskets however mine came with a ton of scratches. I took the extra step and got oem valve cover gaskets from z1 so I knew for sure the gaskets were solid & ended up still having pretty bad leakage on the BRAND NEW covers and gaskets. I had it installed by a mechanic and we tried everything possible to get it to not leak and it still leaks. Not sure if I got a bad set or they are all bad but I’ve definitely heard good and bad things about the aluminum covers I’m just lost at this point because I don’t wanna risk the issue again ordering another set, and i definitely don’t wanna spend $500 on oem covers off Z1. Nor do I want some cheap Chinese plastic covers.

Installed didn’t use supplied bolts used oem bolts and used supplied gasket no leaks will update if that changes fit good remember to use silicone in front corners.

Had these professionally installed on my car and so far I haven’t had any leaks or problems out of them! Don’t want to pay the price for oem ones and i like the red in the engine bay!
