    Well the correct thing to do is always use an airline to clear the plug hole from any dust/debris BEFORE removing the plug... you definitely can get some grime built up in there. Definitely not something you want inside your engine.

      Yeah, but I personally think that is more of a theoretical than practical issue.
      I have had coils for a year and there is really no noticeable buildup.
      Plus, you can just clean it...

        I have no issues with my setup. The only thing was, I had to put that small "holder" on, because the 1.8T coilpacks tend to get loose. This is why 2.0TFSI ones are better, they fit pefectly.
        As the "inventor" of the 1.8t coilpack conversion back in 2005, I have to suggest that if your 1.8t coilpacks came loose, then you didn't trim the plastic and/or rubber as per the original instructions, thus preventing the coils from snapping down onto the sparkplug hex. I still had 3 of the original 115L coils (2 other had failed) this summer when I when I changed my exhaust cam to the RS2 cam and had to remove the cam cover. All five of the coilpacks were "stuck" very firmly to the sparkplugs. As an added bonus, the sparkplugs had never backed out over the 5 years either.

        The 2.0 TFSI coilpacks are taller and have no silicon rubber "ring" to seal the coilpacks into the sparkplug wells. They are too tall for any cover (which I would not recommend anyway).

        As for Paul's comment about debris getting into the cylinder, I always vacuum out the sparkplug wells prior to removing the plugs (I use a piece of 3/4" copper water pipe duct-taped to my shop vac hose to do this).

          I bought my car with the conversion already made, so the easiest fix for me was to make a retainer.

            Your *easiest* fix would have been to trim the coilpack properly. 2 minutes per coil pack.

            The interesting thing about the hold down approach is it *might* act as a heat sink/radiator to disperse heat build-up in the coil packs.

            On that note, the reason why some people, e.g. 034 and EfiExpress, are offering coilpacks that are mounted on the firewall with high tension leads to the sparkplugs is to get the coilpacks away from the engine heat. This is called coil-near-plug (as opposed to coil-on-plug).

              Paul: Can't totally disagree. Depends on care and attention to detail. Here is a photo of a 034 HO coil system installation with a 7A cam cover. I certainly wouldn't call it "rubbish" (but I would have moved the coils away from the turbo heat):



              Here is an example of a EFIExpress D585 LS2 coil system installation (note: the sparkplug leads run UNDER the cam cover, like a 3B, and the coils are away from the turbo heat)

                They are not very tight fitting... and I did not know that yet when I bought my car

                It actually does. I don't think I am going to attach fins to it though

                  Nuhh - still looks untidy to me... All those straggly HT leads trapsed all over the place... but the RS2 badge on the airbox gave me a laugh at least ! Some folk cannot help themselves with a bit of bling

                      Can't please everyone

                      That car is total "sleeper" with zero bling until you open the hood to reveal it's completely RS2'd AAN engine. You missed the fact that the injector cover and the firewall connector rack cover are billet aluminum.

                      BTW, RS2 badges can be purchased outside the Dealer network, without chassis numbers.

                        LMAO @ this thread! FWIW I would only ever fit the OEM Beru coilpack to my car, even if it did cost over £500. They are known to last over 15 years, the coilpack cover stays in place and it works at Audi designed it to. Any other solution doesn't look the same and introduces other potential future problems, albeit at a lower cost and potentially easier path to replacement if (and when) required.

                            I think at 500 pounds a pop id even go for the conversion.
