i've got bosch super plugs (copper core, single electrode), as long at your not using bosch platnum 4 plugs in anycar, these plugs cause misfires beccause you can't gap them. i've checked customer cars that come in with them, you gap spec would be like, .035 and i'd check between on of the electrodes and it would read over .080. but also autolight copper core plugs are in my opinion the second wores plug you can buy, they flow foul out eazy, just because its cheap in price doesn't mean you'll get to the next 60,000 miles service without plug failure. NGK's are probaly the best you can buy with a small budget. i've ran them on my 90 TSi talon heavy on the turbo mods, with no problem. what do i know i've only been doing this everyday for seven years.
