    Spark Plugs for GSi

    Hi i want to change my spark plugs and have read through a lot of threads but havn't found one that is everyone's favourite choice, ok i have read the OE ones are not too good and the NGK iridium ones are but the tips can fall off?

    Any info would be great thanks!

    i run the irridiums mate never had a prob and have heard the tips falling off or breaking but you think how many ppl have these fitted and not had a prob and there is only a hand full that had probs i personaly think it down to wrong pluggs fitted due to the heat

    Take a look at this link, Cossie plugs seem to be a winner, not sure if they'd run on standard map. http://www.astraownersclub.com/vb/sh...d.php?t=195560

    from what I have read one or two people have had a very bad experince, where a tip has fallen off and like chinese whispers it becomes 10 times worse

    I have iridiums in my sri turbo and I have never had any bother with them when i used gm plugs or standard ngk plugs my car had a mis-fire..... the iridiums were the solution (my car is not mapped)

    For the standard map try BKR5EIX, for stage 1 to 3 BKR6EIX. I had 5 and now 6 on stage 2.
