Spark plug Champion or Denso

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.

ive put new denso oem spark plugs and im waiting on my coil packs to come in from ecs tuning and i hope that will fix my problem

I had really good experiance with Denso Iridium on my mk3 2.0 and mk4 12v.

going on almost a year on champion $1.99 copper plugs and my car runs just as good if not better than when I had the oem plugs in there...

Turns out the AutoLite plugs that a local parts store sold me are crap for this engine (actually caused misfires) so I went and got Denso double platinum plugs the next day and put those in.

I decided to go with the Denso Iridium Spark Plugs Part # 5304#4 and am VERY happy with them. My car runs better than it ever has. These plugs were a little expensive but still less than what the dealer wanted for OEM plugs. I definitely recommend them!

I once had to use 99 cent Champion plugs in my car for a few months when I was flat broke. They worked fine but didn't last long.

At this point it's only showing symptoms after idling for 30 seconds or more (and even then not every time), like while waiting at a stop light. Only in first gear, second and beyond have no hesitation. This evening I swapped out the almost new Denso plugs (correct gap) and the problem seems absent.

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)
