ACDelco Iridium Spark Plugs - Set of 4 (LTG)

Stock replacement spark plug for the LTG.

We generally recommend a .028" gap depending on overall power level.  However due to the fragile tip, a proper gapping tool must be used.

Sold in sets of 4.

OEM torque spec is 15ft/lbs. Do not tighten spark plugs on a hot engine.
