What do you all think about the Denso Iridium plugs, good performance and durability? Also what kind of wires should i go with? Any other suggestions are welcome

Thanks

i used them and went back to ngk tr55ix. iridiums. 7164 is the part number. and i will continue to use these. they come pregapped at 55. that is a good gap for n/a.

 

I have the Denso's and MSD 8.8's. The NGK's are great too, and a little cheaper than the Denso's I think. I'm partial to Denso because I was a Toyota Tech for about 12 years and that's primarily what they use and I know they hold up well, although many Toyota's come from the factory with NGK's, depends which plant it was built at. Oh yea, I gapped my Denso's at 55.

The original AC Delco plugs were in great condition, but when I checked the gap on them upon removal, I found 2 plugs gapped at .065, one at .050 and the rest at .045. (spec is .060)

 

The iridiums really are not going to do much for performnce other than last longer. I have used only NGK's in my truck and am very happy with them. Wires, I have run Taylor's, but burned one up on one of my headers. I switched to MSD's because of the boots on them are longer and better than the Taylor's.

 

I like my NGK plugs. I also have some Taylor plug wires and like the them as well. No headers yet, so I can't comment on fit other than it looks like I may not have any problems.

 

i have ngk's also and they seem to work great. along with MSD 8.5mm wires
