Spark Plug Evaluations PLEASE!!!

**vncj96** · 05-12-2009, 07:56 PM

Does any body have any experiance with some of these "performance" plugs like the pulsing plugs or these E3 plugs. Just wondering if anybody has really seen any MPG or performance out of some of these expensive plugs?

I used to have a Dodge Dakota I put some fancy Platinum plugs it and it seemed a bit off, I asked the dealer a friend of mine he said that the computer did not like them. Not sure if our GM products suffer in the same way.

When I bought the truck the previous owner had some iridium tip plugs and it hated those, I got horrible gas mileage, but if those new ones especially the E3 can give me half of the claomed MPG it would be worth it

I have a/c delco irridiums with over 70,000 miles and still look good. I take out every 30,000 miles and put fresh antiseize on them because of aluminum heads.

ive worked for autozone for a long time( was the only one there who knew ANYTHING)
so for me, ive noticed that gm,chevy, ford, all like theire own plugs for some reason
my mustang would only like the autolite plugs and that thing was worked to the nuts, my moms tahoe, only likes the delco platinums, we tried bosch, autolites and nothing worked like the delcos do now.

so i'd go with the delco iridiums or plats

The Delco iridium was was what preciuosly in my beast and it hated them, I went back to the standard OEM platinum and I got 1.5 MPG increase, Steven thanks for the link to Dr. Zeros analysis!!
