High performance spark plugs?
A friend of mine recommended a mechanic to help me install any parts I need in my Camaro.
The mechanic said I should replace the stock spark plugs and wires with high performance ones, as the stock plugs are design to last 100K miles but not for performance. He said he could replace the spark plugs with high performance ones for $20.
Does a so called high performance spark plug really make any difference? $20 doesn't sound too bad.
