Hi,
I am about to invest in some Denso IK20 Iridium Sparkplugs for my GTS-25t as it is misfiring under full throttle and has a bit of a dead spot at 5,000+rpm (Iridiums solved this problem for my last GTS-25t).
I've been reading on the forum about the gap and I find a lot of mention of a .8mm gap. The IK20's come with a 1mm gap; should I change them to .8mm for better performance?
The car only has breathing mods and is otherwise stock.
