Ik22 is one heat range colder than stock,and I have installed these in many 1.8T & FSI cars from stock/mild tune/heavy modded and worked great.
Honesty I've just used Champion all year's or whatever less than five bucks and have never ever given me any issues.
Denso iridium are great for turbo cars
NGK are also good, but in experience denso iridium works better when running more than 1 bar of presseure
I dunno about coil packs but I put in Denso Iridium plugs a couple months ago and they have been working out just fine...
Thanks for the all input guys, I kept the Denso IK22's at the stock .032 and they seem to work grrrrrrrrrrrrrrrreat, all my miss firing issues are gone (probably due to faulty old coils) and the old IK22's I had in there were probably looooong in the tooth with around 50k on them. I do notice the smoother idle and the butt dyno feels it seems to be a bit more eager to go from low revs feels so good to not have to 1/2 step on the gas so it doesn't go into high boost and misfire, drove like that for several months:facepalm:
I have 2.0TFSI coils and new Denso IK22's. So the only other thing that would effect all cylinders is the coil pack harness? What do you guys think?
After switching to the densos IK22 @ .035 it was that "night and day" difference some others are claiming.
Been using the desno IK24's with a .32 gap. Works very well but that plug is a tad to cold. Runs a tad rough untill I get her warmed up.
I installed brand new denso ik24 plugs gapped at .026 and I am still getting misfires.
I tried the denso IK20 and had nothing but misfires.
