    I thought i would change my plugs in my s3. I got a set of denso plugs from epc, part number :pK20PR-P8. Now i took my olds plugs out and they were a small thread which goes into the coil packs. The new ones are bigger at the end, amd you can not unscrew the caps. Are the denso plugs wrong? or are the plugs which are in my car wrong?

    Totally agree with you here! Got denso's last year to try out, few months and the ceramic cracked causing quite a bit of missfiring

    You were lucky mate, when my mates went, the ceramic ended up scoring the bores, wrecking the valve seats and shredding the turbine of the turbo... expensive failure...

    If you have taken the old one out and it is smaller and threaded then the cap is probally stuck in the coil pack. They should be the bigger ends as standard. Some come with a screw on end but I don`t like them as one unscrewed on me and knackered a coil pack :(
