Plugs question
NGK Iridium IX Spark Plugs for $7 (Electrode Tip Material: Iridium tip)
or
NGK V-Power Spark Plugs for $2.40 (Electrode Tip Material: Nickel alloy tip)
2nd question: I am changing out plugs one at a time to see which one of mine is bad, is it a bad idea to start switching in nickel alloy tip ones when the rest are Iridium tipped?
