I am having a JLP 5lb'er installed next week. Which plugs do you recommend, and why?

 

I have heard the DensoIT20's

why?? Dont know, maybe cause they are 90 bucks?? LOL

JLP should be able to tell you why though..

 

I've had that very same pulley on for about 32,000 miles. Right after installing the pulley, I installed NGK BR7EFs(gapped at 0.038") and have been very satisfied with them. They do induce a low-RPM misfire when at idle but I still get 14-15.5 mpg and a pretty good ET/MPH in the 1/4 mile.

I have 8 Denso IT24s waiting to be installed but I'm in no big hurry to do that............yet.
