MITZONE N20 Upgrade Aluminum Valve Cover with Gasket Bolts Kit & Oil Cap for BMW 2012-2018 528i 528i xDrive 328i 328i GT xDrive 320i x5 x3 X1 428i z4 2.0L Replace 11127588412

I bought this and installed on my wife's 2014 BMW X1. It fit well and looked and function much better than the original plastic one that cracked in several places. The part seem to hold up well. It has been over 3 years and over 30K miles and there does not appear to be any problems. The only issue that I had was that I could not use the supplied bolts as they were too short. I took a chance and reused the old aluminum ones and so far so good. Because of this, I purchased another one from the same maker for my daughter's BMW X1 Xdrive35i (6cyl). That one seem to function well too. I needed to replaced her valve cover because of the leaking pcv valve which is a very common problem.

Have had this valve cover on for about 3 months now without any problems. It fit very well and install was a breeze. The gasket fit and formed well. The hardware that was provided is nice and also fit well,(very well coated so it won’t corrode easy). It definitely adds to the look of the engine with the bright silver coating. The coating is also very smooth but very tough and does not scratch easily. So far, so good! I was not sure how this was going to turn out as far as the fit due to an aftermarket aluminum part vs the factory composite part so I took a chance and tried it. I have used this brand of aluminum products on other vehicles such as oil filter housings and have not had any problems whatsoever so far. I would recommend using this brand as a replacement for the plastic valve covers and oil filter housings as aluminum does not crack easily,last longer,( if not forever) on vehicles. Aluminum is definitely the way to go rather than the composite,( plastic) components due to the way it withstands heat allot better than plastic. The trick is to find something that will fit like the factory part and last longer without spending a fortune. This in my opinion is it.

Quick delivery and easy installation

Received cover in good condition, it bolted up and fit great.

Worked great and fit as it should. Only issue was after the install the cap provided has a seal that tend to leak. I am unsure if this was a manufacturing defect or a common issue going to aluminum. I did find a off brand aftermarket seal that is larger than oem to fix this issue.

This worked perfectly for my 2015 BMW x1 with the 2.0 engine. There were some raised spots on the mating surface around some of the bolt holes that I didnt like the look off so I filed them down. Not sure if they were casting defects or what... I am unsure if they would have been a problem or not, but I didnt want to take any chance. Also I ended up using my own hardware for the 2 cam actuators on the front of the valve cover. not 100% if it was in the bag or not.

Very good and reliable👌🏻

Excellent.. Direct replacement of the original factory gasket.. Worked perfect for my 2016 BMW 4 Series Grand Coupe

Ordered the parts and took it to my mechanic to install. He mentioned this was better than any other plastic alternatives. Would order again but hoping it never comes to that.

Good product and much cheaper than OEM. The oil cap was the first place to start leaking but it is very very minor.
