OEM 350Z / G35 VQ35DE Valve Cover & Gasket Kit

I’m glad I went with this genuine Nissan valve cover and valve cover gasket kit. The gaskets have little outward notches to help hold in place while setting the valve cover on the head. There is so much to take off and put on when doing this job! Take my advice and buy this to do the job right the first time.

I just got the engine reassembled today and it started right up. So far so good. The gaskets were no problem-they adhered perfectly so installation of the valve covers was as easy as Nissan makes it. Perfect fit and quick delivery.

6 months since I installed them and 0 leaks and my car feels better can’t go wrong with oem.

Thank God for z1 my engine bay is more cleaner now because of this set

OEM spec valve covers that you want when replacing worn valve covers. I had a oil leak and replacing the valve covers and gasket fixed my leak. definitely recommended to keep your engine from leaking oil.

Good product no issues to date

OEM valve covers were well packaged and delivered in a timely manner. Installation was a pain (passenger side), but is complete. I will continue to do business with Z1

This is one is fresh to my heart ❤️. I, like most people had to do this job twice! Use quality valve covers and seals, do the job once. You'd be happy you did.

Years later and it still holds thank you Z1.

I've had these on for almost 2 years. Still no leaks. Excellent quality.

Perfect fit, great bundle!

As a lot of the other reviews have said, go OEM or you'll be sorry. You're probably replacing these because the unserviceable spark plug recess gaskets are leaking. There are aluminum aftermarket replacement valve covers that offer serviceable gaskets - but the quality is so much worse than OEM. They are close to junk. OEM will last you over 100k miles. Bite the bullet and get the best from Z1.

The leaking at the cover has stopped and this a year that it has been changed. Please dont cheap out an buy a non genuine part for ur engine you will be paying 2x for the job to be done.

oem parts like this ones are a must for this car, chinasee parts do not last the year ,

Nice oem valve cover as describe .fast shipping.thank.s

Good quality part with fast shipping.

after so much time i thought lets make a review. fitment was great ,install was easy 5/5 rating.

These work great! Came with gaskets!

Perfect, great quality

Your oem valve covers fit great with no leaks at a reasonable price Removing them twice is a real pain as I went the cheap hole saw and seal replacement route the first time which worked for a while but piece of mind is a good thing to have. Jim

Fit perfectly on my FX35 and stopped all my leaking, for sure an OEM product quality was exactly like the originals.

Fits like OEM... it would have been nice of Nissan to let you just replace the spark plug tube gaskets. No more leaks with the new ones.

Loved the price and oe quality no leaks now!

Can't go wrong with OEM. Changing the valve covers is no easy task so better to get OEM quality over the aftermarket brands for better peace of mind!

Excellent buying experience from ordering to packing and delivery time.

If you want the best trouble free installation, get these OEM covers. There are plenty of cheap covers out there but you're replacing these because the spark plug tube gaskets are leaking and they aren't replaceable, so do it right (and once). The non-OEM will not fit as good as these OEM. Oh, and make sure to get all the oil out of the tubes and you probably need to replace the plugs as well. It's the usual, "As long as I'm doing this..."

Great quality, fit like it should, packaged well, well built

Awesome prices, Awesome shipping, getting ready to tackle having to replace these still have other stuff to order! Can't wait.

Exactly as it states. OEM parts, can't complain at all, A1 quality.

Quality product, easy ordering and competitive pricing. One cannot ask for more! Not to forget, the excellent customer service and fast delivery. For the extensive labor involved in replacing the valve gaskets, it is worth while replacing the valve covers and spark plugs at the same time. Always use OEM product, original ones lasted 158K miles. These should do same, not worth taking risk on aftermarket product. Highly recommended!

My old cover was leaking oil around the spark plug rings and needed to be replaced. No issues what so ever with the install and Z1 saved me $$ over getting the cover and gaskets from the dealer.

Had to replace valve covers when I had oil leaking into the spark plug hole. About 1000 miles after installation and there is no sign of oil leakage.

Best to use OEM valve covers and these are I also ordered all the plenum gaskets and pvc hose and valve cover cross over hose , every thing went well

Installed my valve covers with new plenum gaskets , throttle body gasket , rtv ultra gray sealant , silicone pvc hose and also the valve cover crossover hose these two hose's get very hard and brittle. My install took time but all is well , all my parts are from Z1 Motorsports very happy with them
