I have an 07 Sierra with the 4.3L and a 5 spd manual. I swapped the stock plugs for E3 plugs when I had just over 5,000 miles on my truck. I now have 17,200 miles on the truck. they have not given me any trouble. What I did notice is how much easier the truck starts. The extra power also let me lighten up on the throttle. I've been able to shave 200-300 rpm's off my shift points. Overall, I picked up 1-1.5 mpg. Not as much as I had hoped for, but every little bit helps. If you do swap plugs, post a message here as to how they work out. Best of Luck!

e3 spark plugs
Ive found that the stock factory plugs seem to work best on a stock to mild engines. Save your money.

I just bought a set of the E3.62 spark plugs for my 04 silverado 5.3. i only spent about 50 bucks and that was with some anti-seize. Bought them at pep boys. They were advertising about 6 bucks a plug.

A guy at work just put them into his 2006 Escalade EXT. and he said that he already has a .5 mileage improvement. I personally have never used them, but I would think that the best would be the AcDelco or even Bosch plugs for an upgrade.2004 Chevy Colorado

I have put them in my last 2 trucks & I love them. From now on when ever i got another vehicle that is the first thing I am going to buy. I really noticed a difference in my last truck (2006 Chevy Z71) with mileage...& Gracer 29 im jealous of you now because i spent about $80 on my plugs
