are these good plugs for the LT1?, i just saw a set and bought them for 25 bucks, should i have bought the irridium plugs? someone told me the NGK TR55's were the best plugs for the LT1 so i bought them, but are they the right ones?

 

I heard the same thing from a friend of mine, he ran them in his 94 z28...it ran pretty good. Never ran those in mine though, i got some tr 6's, but thats only cause i have nitrous though. Slap 'em in there, i dont think you will be dissapointed.


95 z28______290hr-12 comp cam, crane cam valve springs, msd coil, taylor pro 8mm wires with braided boot covers, cool air intake, air foil, 150 shot nitrous express, 3:73 gears, hooker comp headers, cut out exhaust. pro flow mufflers

 

thanks man, appreciate the input.
