I have decided to go with the denso's. I can get them locally for $11. I believe you get what you pay for. I rather pay $90 now, than a lot more later. Thanx for the info.
My Denso IT22's were great until I went to the track. I cracked one on the second pass and I had a very safe tune from Strictly Performance. After that, I yanked the rest and threw them in the trash. Just my .02. I wont be buying them again ... ever.
