    Constant fouling of plug on cylinder 3

    That is my next step, would my compression be worse if it was piston rings compared to valve seals? Wondering how I can pinpoint one issue and eliminate another. Thanks for the reply

    Alternatives to stock air filter/engine cover.

    @ROH ECHT Thanks for the response, i spoke to a friend of mine who suggested in-line air filters. I found some on various sites but nothing specific to the mk5 and didn't want to mess with trims. Was curious if anyone had any experience with these? Thanks for the info, sounds like I'm going...

    Alternatives to stock air filter/engine cover.

    Hi everyone. I just wanted to find out what people have in terms of filters/replacements for the stock airbox/engine cover on a mk5 gti. I have an APR carbonio intake and ideally would like to keep it because I have a few carbon pieces under the hood. But I cannot stand constantly having to...

    I have a new N75 valve on the way and hoping it'll fix the issue otherwise no doubt a trip to the dealer will be in order! Plus the video I recorder is on my phone I just broke today. Just another thing on the list haha. Will update I guess when I have installed the N75 valve
