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

These things are awsome! Ive had about 6 different G35s now all of them with the warpped plastic valve covers. But these aluminums are great. They look great. install really easy for anyone mechanically inclined. Good quality gaskets. The only thing that i dont like is that I am goiing to have to figure out some way to clean my engine bay up more to show these things off...

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.

Fit my DE 350z perfectly. The included gaskets were pretty stiff, I recommend getting OEM. Spark plug seals are great and replaceable, unlike the OEM valve covers. The threaded holes for the coil packs and wire brackets weren’t deep enough, get some shorter bolts or a few washers. The paint isn’t that durable but you don’t notice once it’s installed. Only took of a star cause of the threaded hole issue. Definitely recommend if you’re doing a valve cover job.

Very stylish. Holds oil in. No problems installing myself.

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.

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.

I got this item two day a go. It seems that there is no quality check at the factory before they ship it out of the Amazon warehouse. I will return it to get the replacement; I hope to get a good quality cover. and finally got replacement but replacement were bad as well. Screw bag already cut in 1/2 and screws were everywhere in box and cast are uneven for screw.

Valve covers fit perfectly. Took a 12 hour road trip after installation and no leaks. Did use oem gaskets though. Covers scratch very easily, paint could be better.
