    If you look at this pic, you see that the sparkplug holes are quite deep up in the combustion chamber, so no chance they hit the pistons.

        Pulled the trigger but the plugs in and kicked her in the guts with baited breath,.

        All good, much smoother on idle and sounding strong.

        Phew. Thank you for your input!

          Plenty of room for spark plug! Take a closer look by opening the picture.

            I´ve replaced the 5 plugs on my ABY less than 1000km ago, out came the VAG/Bosch F5DPOR with 50.000km on them (90% on LPG) they where light grey and had no imerfection at all, in went 5 new Bosch F5PDOR made in Germany bought from one of those internet car parts seller.........and less than 1000km later the engine developed a clicking sound like an exaust leak an soon after begun to fail as I gave it some thorttle....WTF! Took the first plug out and...suprise....the ceramic core had worked itself lose from the metal outer part, than removed the 2nd one...same problem, 3rd one the same as the 4th and 5th...WHAT..all 5 F**KING new spark plugs had the ceramic core going round and round like a "merry go round".

            Put the old ones back and all is good with engine now...have to buy new plugs but this time I´ll go to my VAG dealer, it will cost more but quality won´t be so bad, I hope!

            WTF is going on with Bosch it´s not like they´re making the plugs in china as the box states "made in Germany" are they in the business of loosing business!
            Well I must correct what I´ve stated above!

            I don´t want to defend the quality of the Bosch spark plugs but in the other hand don´t want Bosch to take the blames from my own mistakes so here it goes:

            The failure of the Bosch spark plugs stated by me in the quoted post were of my own fault as I by mistake overtorqued them all causing the break of the seal between the ceramic core and the outer metal sleeve!

                I just installed the PFR7B and my RS2 is running really nicely as a result, its pretty standard though.

                  Guys, i want to order NGK BKR8EIX , but local parts shop tell me, that they have a bad experience with NGK these days...Lot of reclamations of burned that ceramic nose. He told me, that NGK is now made in France these days and not Japan as they was. He told me that French made is **** and some Japan left, is good

                    That's a bit odd, we sell a lot of NGK and I can't think of any issues with the plugs.

                    Cheers

                      I have been running with these plugs for just over a year and had no issues ( rs2 + spec )

                            All this spark plug fapperino makes my head spin.

                            You can use plain simple copper spark plugs at 1.50 a piece, as long as they are the correct heat range and gap.
                            Just change them every time you change your oil.

                            None of this platinum iridium <insert **** here> makes the plug any better at doing what it does. It only makes it *last* longer. Meaning you can go like 80 000km on one set of plugs.
                            Make sure you have 5 bosch or 7 ngk heat range (1 range colder if you are doing 300hp per liter or E85), make sure the gap is 0.6mm after you pass 250hp/liter. Below that doesn't even matter.
