I'm ready to swap plugs at 87000. Is there a difference between the HO plugs and the non-HO plugs... and which one's do I need to get? I know this thing came with platinum but I've read alot about not using them.

 

You'll get better life out of the platinums and are a better overall built plug. I run NGK Iridiums.

 

i run the ngk iridium laser....best plugs ive ever run, and ive gone from the e3 to the bosch platinum 4 .....

 

A lot of guys on here swear on the autolite cheap copper plugs.

 

lol u must of read alot for only 9 posts....althought i read from july until earlier this month, just started posting lol.....

 

I have heard various things, like you two swear by the NGKs and some others have said anything but copper cores run like crap.. sure makes it hard to choose when it comes time lol.

 

I picked Autolite 3923 for my 3.7. Also hear alot about anything but copper running bad. especially platinums, dont know why.

 

not for me my ngk's run GREAT and they last longer whoever says anything but copper, also must use permatex instead of felpro gaskets or mopar gaskets....

its all about spark efficeincy, the autolites wouldnt even run in my chevy lol misfire all over the place, make sure u check the gapping before installing as well.....


did u know your supposed to change ur spark plugs every 30k? bet you diditn know that

 

I also run the autolite copper core. Tried iridium, platinum, you name it. None work better in my truck than good ol copper core. I change them every 30k. No issues, no problems.

 

Mine were not changed for 100,000km lol
I believe the gap for these trucks is .35?
