      Curious what everyone runs for plugs in their vw racers.

      I use Bosch W3CC or NGK BR10ES or B10EV (when I can find them). Very cold "heat range" for the 14:1 compression I run.

      how do you like them compared to traditional plugs, or dare I say vs Platinums?

      I'm quite pleased with Iridiums - I made the switch b/c of a rumored HP gain (very minimal - maybe 1 or 2) over Copper or Silver plugs but after 6 years with them, I have no complaints. In fact, I use the same plugs in my street car.
      For whatever reason, platinum plugs don't work well in 16v cars. I used one set that caused to car to have a horrible mis-fire. Turned out the plug had carboned up...don't know why or how and haven't had a problem with other similar style plugs (tri-electrode).

      very common complaint... the only cars that seem to run well with them had them "stock", but then the cars run even better when switched to coppers (i.e. there was a writeup from a Mk4 driver who proved it with his 1.8t)

      It's kind of important to post what configuration you are running.

      We change ours every couple of race nights to get A/F reads on the plug.

      .030 is a good suggested starting point, if you experience spark "blow out" under boost, reduce gap .002 until it stops... .028 is considered "stock gap" for some VW engines
      edit... wait, Carbs on 14:1?
      what ignition system are you using?

      assuming your not running resistor plugs... you could try .040, if you get misses, your gonna have to make the gaps smaller until it goes away

      unless your getting mis-fires... a Dyno will tell you
      I haven't indexed my plugs yet, but from what I read and understand... I believe in it

      NGK Racing Competition B10EGV (B-one-zero-E-G-V) The zero looks like an 'oh' on the plug.

      Hi all, I have a 2007 GTI 2.0T that just turned 40K. I want to change the spark plugs. All I keep hearing about is NGK or Bosch Iridium plugs. I go to all of the local outlets and they look at me like I am from another planet unless I want Autolites. Can anyone give me part numbers for The NGKs or the Bosch. Car is stock and street driven only. Thanks
