Spark Plugs - 4 Cycle - Denso Plugs

by Denso $3.00

The spark plug can be an important tuning tool for your engine.  You use a hotter plug in cooler conditions and cooler plug in warmer conditions.  When you go from a cooler to hotter plug you are leaning out the motor slightly.

The lower the number, the hotter the plug.
