im runnig the autolites 3922 and i hurd e3s wernt all they were cracked up to be

 

They worked great in my truck but the biggest diffrence was in the wife's durango. I put them in and ran a tank of E85 on the superchips 93 tune and it was a totally different truck.

If you try them just make sure you get the right one for your application.

 

i just wana get the same heat range as the autolites im happy with then

 

Your heat ranges will differ with mods that you may put on. If you have colder air coming in, say, from a cold air intake (although, most are just RAM air's) then it will require it in order to not Ping.
Honestly, I pulled my plugs since I'm close to 100k miles and i've been pinging badly. i replaced with the cheap copper plugs and no more ping. The plugs had been replaced once, but with platinums.

What I had learned with my mustang is that platinum plugs, while they last longer, with iron heads they tend to ping. Just listen to V8 chevy trucks. The usually ping from the factory. It's cuza the plugs. Ya swap to copper... it's gone. I only run copper plugs anymore, even though they only have like 1/3 the lifetime span, just for this sole reason.

Plus... it gives me more reason to take time aside and check everything over and do an overhaual/checkup.

 

Hey guys I run the autolites in mine. I did some research on the e3 and saw a youtube video of e3 spark plugs that burnt up and cracked. Kinda turned me off of those plugs.

 

The E3 Plugs are still workin' well in the truck. They're nothing special (as I wrote back in 2009), but they're not $hit either. They're just performing like a good quality plug should. No problems to date with the E3's.

 

i am using the e3 and no problem yet i use the # e3 refer to me as a remplacement number for the stock plug smooth idle runs good since 30 000km
