I dont think it s gonna be a problem because it s only because we change the octane
to 91 and the engine run hotter or colder i am not sure i am not a mechanic boy

better looking than geno
Not so much for economy or performance...I switched because I run an "aggressive" tune often and colder plugs = less chance of detonation. More or less what if my gas isn't right...and I'm running the quarter.

all my plugs were GROSSLY over torqued from the factory. nearly twice the factory torque specs on one of them.

Well, I currently have Gotts mod, 4" heartthrob with magnaflow muffler, and 5* 91oct perf/tow tune. Airraid CAI sitting on the floor. ..just checking the difference between intake air temps between the two.
