CaliConquestAlex Posted August 29, 2008 Report Share Posted August 29, 2008 I'm getting ready to swap out my spark plugs and I've been looking into the E3 spark plugs with diamond fire technology. On the E3 spark plug website they have a vid from Horsepower TV which shows them head to head against another plug. The E3's used less fuel and made about 5 hp more than the competition. I wanted to know if there are any members running them? I'm going to pick up a set from kragen auto parts for about $6 each and I'll update.

mikec Posted August 29, 2008 Report Share Posted August 29, 2008 Just make sure they withstand the rigors of a turbo motor. Many "high performance" plugs literally fragment under the temp/pressure loads of a turbo engine. Some die after just a few hundred miles, others last a couple thousand - just long enough for you to think "it's been a while and they're okay, they're probably fine." Then when you quit checking routinely they disintegrate and leave you stranded. I've never heard of E3 so I don't know if they'll have this problem or not. 5HP on a dyno test though is darn near noise. Just changing the coolant temp a little bit can make that much difference. How brand-new were the "regular" plugs used on the test? mike c. Link to comment Share on other sites More sharing options...

idriftnaked707 Posted August 29, 2008 Report Share Posted August 29, 2008 im actually a manager @ a kragen auto parts, i honestly dont think much of the e3, mostly because of lack of feedback from customers, however when it comes to the e3's used on lawnmowers and such, people swear by those plugs.

CaliConquestAlex Posted August 29, 2008 Author Report Share Posted August 29, 2008 How about a discount on parts? I keep the car in fairfield and it'd be worth the drive up to dixon if you can hook it up. Link to comment Share on other sites More sharing options...
JustPaus_88TSi Posted August 29, 2008 Report Share Posted August 29, 2008 I just saw those plugs on Gearz. They seem pretty interesting, but like Mike said i'd be cautious.. Also, it'd be great if we could find out the comparative heat ranges. Link to comment Share on other sites More sharing options...
CaliConquestAlex Posted September 3, 2008 Author Report Share Posted September 3, 2008 (edited) I put these plugs in and noticed a significant increase in performance when starting the car and while it's running. The car starts almost immediately with the turn of the key, which is good for an MPI car. I drove the car today, Idle is much smoother and the car pulls strong up to 5900 rpms where I didn't go above that. It was still making power but the tune isn't that dialed in for full throttle yet. I'll report back about the durability and gas mileage stuff if they become an issue. I would recommend checking them out. I don't see the electrode breaking off because the 3 prongs holding it appear to be very strong.

TopDawg_43 Posted September 3, 2008 Report Share Posted September 3, 2008 I had one in my lawnmower. It worked fine until the engine blew-up. Link to comment Share on other sites More sharing options...
Szester Posted September 6, 2008 Report Share Posted September 6, 2008 Haha, yes, i have them in my Deere baby. Also used them in my 3.8 stang for a little while. I didnt notice a difference though. Of course Fords 3.8 will run like s*** no matter what you do to it. Link to comment Share on other sites More sharing options...
j5 Posted September 22, 2008 Report Share Posted September 22, 2008 (edited) Kinda looks like the spark was bigger due to two things, the center electrode being more exposed and the larger ground area providing a less resisstance making a bigger spark. The larger area of ground electrode may cause detonation under boost, it'll stay hotter longer. Who knows? Edited September 22, 2008 by j5 Link to comment Share on other sites More sharing options...
macrophage Posted September 23, 2008 Report Share Posted September 23, 2008 (edited) i think the best way to test those plugs is to put the car on a dyno and do two test, one with E3 and one without.

totiturbo2 Posted February 1, 2009 Report Share Posted February 1, 2009 i think the best way to test those plugs is to put the car on a dyno and do two test, one with E3 and one without. use rotary plugs, they the best if you want the number i can loook. if not then jus ask for turbo two plugs, a cold plug Link to comment Share on other sites More sharing options...
monkeywrench Posted February 2, 2009 Report Share Posted February 2, 2009 (edited) Save your money and get the NGK (or similar quality) plugs that cost 1.99 each. Your butt dyno will measure a 20 horsepower dollar increase! Edited February 2, 2009 by monkeywrench Link to comment Share on other sites More sharing options...
