Spark plug Denso or OEM Volkswagen

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:

My CC is 2 years old and I have accumulated 65k miles. I changed the plugs at 60k. They looked pretty toastyso I am glad I did.

Plugs 97K on my 2010 original ones...working great (lots of highway miles). I'll be changing them at 100K.

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.

Just replaced mine with Denso Iridiums, seems to be doing good.

I have always used the denso iridiums for big turbo use. They are a bit cooler then the BKR7E, and they last forever, no fiddling around with plugs. I even have had the head off the car and left the same damn plugs in it lol. Ya, they are more expensive, but I like the convenience of just never touching them.

For the misfiring check your spark plugs it can be that simple... i got a mkiv golf too.

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.

All the recommended denso plugs have the wrong gap. They list 1.1mm gap for the 2.0t The recommended gap should be .7 to .8 mm Plus the "20" heat range misfired a lot in the cold for me (about 20 deg F)
