Spark plug Bosch or Denso

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:

Bosch W7DTC plugs were the best, caint get them no mores, use NGK BP6ET plugs instead.

Bosch F3cs @27psi no issues and no gapping

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.

I pulled the plugs this morning and replaced them with Bosch cooper plugs, the only match that was available in local Autozone. There are no more misfires (for now), which makes plugs the culprit.

Changing the plugs from bkr7e's to denso ik27's helped a bit too.

Do not use the Silber plugs. Mileage and performance suffers.

I've had nothing but trouble with the Bosch plugs, from their cheap-o line to their IR Fusion line...
