Looking for thoughts on E3, They didnt work well in my old 95 jeep I got some fouling and missing.

HP TV showed E3 dyno prove they work and lower emissions. But it is TV cant believe it all.

NGK tr55IX, I know they are pricey but I want good plugs for MPG & HP.

Truck is just bolt ons for now

 

AC Delco factory plugs would be great for you.

Im sure others will chime in.

 

stock ac delco or stock ngk plugs.

 

No need for some fancy *** plug and Iridiums are very over rated and over priced. I just get some Bosch Platinums from the parts store.

 

I got over 120k out of my stock iridiums plugs, new iridium plugs cost 80 bucks that's peace of mind knowing I can get 120k again. So you do the math.. I'm running tr6 now because of the H/C. You cant beat the stock plugs for the dependablity..

 

The stock ac delco or stock ngk will do just fine or go to an ngk tr55. Never been a fan of the Bosch plugs, seen them start misfiring with in 10k-20k miles in some vehicles. I cannot ever bring myself to spend 80 on iridium plugs, way over priced.

 

When I ran NGKs, I couldnt get them to last past 15k. They started missing like crazy.

 

An NGK TR plug is not made to go a long distance, just for performance. I changed my tr6's in less miles than that.

 

yea, when I ran TR6s when I had a 200 shot, I changed them every 3-5k. I had TR55s with my H/C and could stretch it to 15k, but started having issues.

 

Stay with delco...I have a low mile set if you want them cheap
