Advantage to Denso's?
 

Well, I bought some Denso Iridium IT20 Spark plugs about a year ago, and they're STILL sitting on my desk right in front of me. I plan on installing them soon, but I had a question as well.
What is the advantage in having them? Ive heard that it improves idle quality, etc, but what are some other reasons??

THANKS FELLAS!! :beers:

TTT

cmon guys!

Fewer misses at higher RPM's as well. Somebody on here has done a complete plug comparison with graphs. Denso's were the best bar none in the test.

They are great, I switched form NGK TR-6's and will never go back, but I'll let the experts answer you on why they're better

Nothing like some real tuner tales to top it off, LMAO;)

It looks like the Fast and the Furious crew have been using them with their usual incredible results. This is probably before the NAWS.:bows:
