E3 Plugs?
E3 Plugs? Just saw Horse Power TV on Spike and they ran these plugs against another leading plug and gained about 5 HP and a little better fuel efficiency. Anyone used these? Thanks
I have the TR55's and have had no problems. I debated for a long time on what to use. i like working on the car so if I have to change plugs every 20-30,000 miles I'm fine with that.

Waste man...I saw that too and it made me laugh. I had the E3s on my 96 Z28, It felt the same power wise(never dynod), it got the same if not worse milege and two plugs went out before they hit 8k miles. I replaced them with cheap autolites to sell the car and it ran better with the autolites than it ever did with those damn wastes of money known as E3s.
I know a guy that has built engines for many many years and he always ran autolite coppers and had great results with em.

E3's are garbage! I bought a set for my Silverado. Paid an arm and a leg, did the install, then drove for a month. The truck seemed to respond well to the plugs. Then the trouble started. At WOT truck would cough and sputter. I couldn't pass a diesel Buick! Truck showed downstream O2 codes.
I took the plugs out, all were fouled. Cleared codes, replaced plugs with recommended AC Delco and all is right with the world.
DO NOT WASTE YOUR MONEY ON THE E3's!!!!!!!!!!!!!!!!

I used them in my Mazda didn't seen any gains in mpg nor loss. Still at 38mpg with the a/c blasting. Car does have a slight miss at 4000 +rpms. wasn't there before.
I suggest stay with what works.

Wow, I put these things in my car not too long ago. I actually did notice a difference right away. More responsive and a touch more power. Highway mileage is just over 25mpg now (was at 23-24). So far so good. Hopefully they don't deuce and leave me hating em too. Who knows, maybe I'm lucky and the Pontiac Gods are protecting my ride...
