    Default ac 41-101 spark plugs in carb engine

    Ordered a set of plugs for my 2003 outback with the 310hp carbureted engine.They sent me the ac 41-101 plugs.I guess these are for the fuel injected engines with cats.Will they be ok in my engine and if so what should I gap them at?

    41-101 are iridium and will work fine, just a lot more expensive. Standard plug is MR43T which is all you need for carb motors.
