    I am looking for advice on what spark plugs to go for in my 1.8 T (AEB) Engine. I am looking to tune the engine over 300bhp.

    I know the Bosch F5DPOR plugs work well in the RS2, S2 and the Vauxhall 2 litre turbo engine.

    Thanks in advance

    NGK BKR6e's are what I use. They are copper plugs and they work very well.

    They are super cheap (under a tenner) but need replaced about every 6k. Is a ten min job though.

    Gapped at 0.032 if standard or 0.028 is chipped.

    If you get a bigger turbo its best to go for a plug one step colder and get the BKR7e's.

    Hope this helps.

    Yeah my car used to have those when I bought it. They last far longer but do not perform quite as well.

    Those will be fine if you cant be bothered changing them as frequently.

    I read in another post about Denso iridium IK20 plugs being the best for performance in A4 & S4.
    I was wanting to order some but was unsure if the gap is right in them but maybe somone could shed some light on that for me please.
    If the gap is not right is there a way of making the gap bigger?

    I have the same plugs that Supie is on about and they seem very good, the others like the iridiums etc dont need to be replaces as often. Speak to the tuner thats doing the work they should have a good idea of what works in the setups they map.
    There is a fair bit of choice the best thing to do is ask then choose what you think is bet for your setup colder, longer lasting etc.

    So if i buy 4 BKR6E they will definetley be copper ones?
    I see some on ebay and it says will fit many cars I specified the gap I need 0.032. So as far as I can tell from you guys everything should be ok?
    I havent ordered yet until I get some feedback on this from you helpful ppl! [FONT=Arial, Helvetica, sans-serif][/FONT]

    Bosch F5DP0R's - recommended for use in all tuned S4's. Have them in my stage3+ .... work very well and last for 20K miles before they require changing.

    Not the answers I was looking for guys. I dont have an S4 and my car is not tuned yet.

    It adds to the topic though!
    I am sticking with the copper ones all the same for the power improvements that soupie mentioned above.
    So if my previous question could be answered I would be very grateful.

    Sent a email to Javad Shadzio at 034 motorsport and he said the Bosch F5 DPOR plugs will be great in the AEB 1.8T engine. So thats what i am putting in as theses are great plugs.

    Yeah just check that the gap is 0.032 and you will be fine and dandy mate.

    Bosch plugs at 0.6mm will handle 2 bar boost.
