spark plugs...which ones light up your life

alright you know how you always hear this spark plug is better or this one is but which ones are really the best
we got the good ol' fashioned coppers that require you to gap them
then we got the platinums and the double platinums
the E3's which boast that their special design allows the boom to go in all directions
then you got your iridiums which seemed to rum good in my Mystique but haven't tried them in the Eclipse on have used the E3's so far
then you got the Bosch I2's or I4's or whatever you call them where they have multiple metal ends around the center conductor
Bosch's I always get mixed messages from people mechanics and consumer's alike I just don't hear much of the others
now what do you guys run what really bring the fire to your heart...the BOOM! to your block what's the what's your spark of life
what's your reccomend and maybe I even missed one that yo guys have

I use the good ol reliable and cheap NGK TR6 plugs. Never had a failure with them.

BCPR7ES - One step colder than stock and I gap them to .025

NGK's one step colder than stock

I run BKR7E's gapped to 0.028, down from the stock 0.044" gap. Dang Mike 0.25" gap ha ha that's a huge gap!

They are about $2 a plug and work great. Don't buy into the hype and spend a fortune on plugs.

Dont buy into the Hype, E3s are overpriced crap. Good old fashion NGK coppers. 4306's for my car is 1 step colder.

On a turbo car that your serious about running, you shouldnt be leaving your plugs in that long to begin with, so theres no reason IMO to step up to more expensive Iridium's. Platinum plugs and turbos dont mix either, platinum stays hot to long

I've run the same plugs for 5 years and always been at the same power level each year on the dyno. All with $8.00's worth of plugs. And when I say same plugs I mean I have never changed the plugs, pull them every once in a while to look at them but if your car is running and getting the plugs to self cleaning temps you should be fine running them for a long time.

Ngk TR55's and ill prolly run a TR7 when i go boost.

I hate you, jerk!

I believe Jason uses the same plug as myself, minus his is a different size, hence the different stock number.

Whatever you do, don't buy the E3's... many a people I talk to actually LOST performance and MPG's shortly after putting these in. I had them in for about 3 months before I went from 23 MPG to about 17... then went back to good ole NGK's... I use Iridiums but thats just my preference.

I have Iridiums too and wish now that I wouldn't have paid for them.

NGK is my preferance.... NipenDenso plugs are about the same as NGK just incase anyone wanted to know

NEVER use Bosch

Autolites suck

NGK. One step colder. Tried Bosch--for about 500 miles.
