I have done a fair amount of searching and there never really seems to be a definitive answer on the spark plug front.
I have a stage 1 ED30 with ITG at around 310bhp. Any ideas what would be suitable? There are plenty of statements saying OEM spec ones are fine but is this correct for mapped K04's?
Cheers
Standards are fine, just make sure they are gaped correctly (0.28")
You can get them from Dealers or TPS, they're around the £35 mark for a set of 4
