I have a problem with my car, sometimes when im accelerating and it gets into high boost and rpm it cuts out and seems like a missfire. I think it is time for me to change my plugs anyway so im going to do that first. Im running stock plugs for a 1994 ssei and what i've done to the car include, Intake with K&N cone, flowmaster muffler, no cat resonator instead, msd ignition, and msd 8.5mm wires. Im thinking of going one degree colder for my plugs, do you think this would be a good idea or should i go stock? Im running ngk right now, does anyone know which ones would be a degree colder? Thanks.
