NGK TR55 for stock 02 Formula I am going to change the plugs in my Formula this weekend and was wondering if TR55's are ok? Some of my machanics at work are recommending I stay with Iridium plugs but I have always heard good things from TR55's.
I pulled a couple the other day and they aren't that bad. However, I do have a small miss at idle so I will probably change the plugs and wires. Car has DENSO plugs in it...I thought they would be factory AC delcos (57k miles).
What do you all run? I also noticed the gap in the Denso plugs were only .055 not .006.

Iridiums won't do any better than TR55's.

If its actually stock I would go to the Pontiac dealer and get stock Delco plugs. NGKs are great through, I'm runnin them in both my F bodies. Can't beat 'em for the price. Actually, my Eclipse OEM plug is NGK lol.

let me put it this way, if you
shoot a colt AR, then stick with the AC delco plugs
shoot an Olympic Arms or Atlantic AR, then go with autolite or champion plugs
shoot a Rock River then go with plain NGK TR55's
shoot a bushmaster then get NGK iridiums TR55IX
shoot a wilson then get denso iridiums.
if you get pulstar plugs, shoot your car and yourself

shoot a Rock River then go with plain NGK TR55's...How did Bushmaster get Iridiums lol? Bushmasters are no better (or worse) than RRA.
That one fits me lol. I have 2 RRA's and one S&W which is in 5.45x39.
What gap should I run? I've seen people say .050 and .055
