Thanks for the info. I might have to check them out!

Heat range is built into the plug (how much heat the plug can remove from the cylinder). How much you should gap your plugs is a function of how much electricity your car's ignition system can generate. More gap increases the resistance and reqires more electricity, but generates a bigger spark. Gap it too small and you are not taking advantage of what could be more reliable ignition. Gap it too much and you will not ignite the fuel/air mixture every time which can lead to lower horsepower, rough running (although the ECU may compensate somehow), etc.TheJezter said:My question is, obviously being one heat range colder, these plugs have a smaller gap (.8mm vs 1.1mm on the IK20's). Is this a problem or do I need to regap to some other value (which would then change the heat range I'm assuming)
I agree with you Totally... I never thought these plugs could make such a HUGE and noticeable difference in performance. I highly recoommend them especially for a B5 running 15-17psi Boost.WHITE1.8T-B5 said:I just installed my new Denso Iridium spark plugs, $13 a piece and the car rides so much better, it feels like a new car and it is just sssoooo smooth, and accelerates better, I have a 1999 B5 tip. I recomend this to all B5 drivers. when I took out my old plugs they were Bosh super and it drove good but this is soo much better, I bought the Bosh super like 3 months ago and it was a great upgrade but his Denso are the best.
So those Bosh are going to the trash now!!
Cali boy's got a pointJB said:you guys are crazy :crazy:
Iridium is more durable than platinum, platinum is more durable than copper.
Heck, at $1.62/ea I'd buy a set every 5K miles.crew217 said:That good ole $1.62 denso prolly gives better performance than your $13 plugs.
