Thread: So, I decided to try a set of E3 spark plugs...

Curiosity finally got the best of me and I picked up a set of E3 plugs the other day. My cost from work was only ~$5/plug, so I thought I'd see how they work in a non-stock 3800. Start-up and idle were smooth. It free-revved easily, and my AFR's looked alright.

On the test drive, however, it would misfire, cut out, and almost die anytime I put a moderate load on the car. ?!?!?! I drove the car for the rest of the day like this. Last night, I pulled them out. 2 of them had a fair amount of soot/fuel-fouling, while the other 4 looked like almost-new plugs. I can only assume the 2 dirty ones were not firing properly... Oh well. At least I gave them a shot. Maybe they would be alright if all 6 fired the same, but this particular set did not leave me wanting to try them again anytime soon.

A new set of AC's, and the car is running like a champ!

Sounds about right.

LOL.

LOL e3's

But one other thing, are you running stock heat range iridiums on that mod list in your signiture?

I have them in my old 94 Bonne SSEi, but its completely stock and it ran fine with them. But I wouldn't put them in the GTP and definitely not when I get deep into modding.

Pulstar plugs make me kind of curious... 16.99 a plug? Holy poop, what's the big deal about them?

Most people with E3's in their 3800s smash the plugs in, iirc. Thanks for the experiment, though.

They do what???

Luckily, I didn't smash any plugs... They do not protrude any further than a standard plug.

BTW, the plugs I put in are not iridium, nor are they the stock heat range.

Probably just because the ones that were in there were fouled out and old and needed replaced.
