    Just a quick post to see if anyone else has purchased and installed the Fel-Pro VS50823R valve cover gasket kit on their gen 3?

    I read the reviews online and somewhere on youtube that the spark plug seals are too big on the fel-pro gasket kit and did not fit and others say they froze them and they fit and others say they worked good, so I am looking for real world experience on here as some of those amazon reviews could be user error or not.

    I am thinking of installing a fel-pro kit on my gen 3 since it's half the price of the mahle and I get it next day vs a week later on the latter. I personally have used fel-pro gaskets before and never had an issue like I read with these gen 3 kits. I bought and installed a Mahle valve cover gasket on my wifes Honda and it appeared to be larger than the OEM as there was a large amount sticking out which ultimately just ended up needing to be stretched out a bit and fit perfect after.
