any one running these plug on lt1 ? I was talk to some hp guy running low 10 or 11 today, and most running E3 Spark Plug, and they have some kind of header and it a bitch to change plug, so they change 5 year or 100k miles. Any of you guy running these plug and felt different ? any miss fire ?

 

Junk just run the ngk tr55 plugs

 

^ what he said

 

I just put that 80 miles ago, I guest I stick with tr55 at 050 hehe. thanks !

 

dont fall for the hype.. was your hypertech that good? about the same thing with the plugs.. probably cost 4 times the amount of an ngk tr55 and perform no better than a stock plug.

looks like the spark would be shrouded by all the metal around the tip anyway..

 

yea my hypertech is do what it say it do. I just dont like how my fan keep running all time hehe. We did a test on my friend corvett , tune the gear, tire size and coolant tempeture, he did feel a big different on coolant temperture and some hp he say. he alway running over 210 on daily drive, after tune it, he running 180-190 all time. but I put back to stock tune on his vet, now he running 210 almost every time now. cause he too cheap to buy it hehe.
