what is the best brand of spark plug to run in a 11' mazda 3 2.0l?
I used to run autolite and ngk in my previous cars and trucks and good luck with either and bad with the only set of bosch that i ran. What do you guys prefer and what model do you suggest to run?
Also, on the iridium plugs for this model, how do you guys gap them?
