NGK Laser Iridium Spark Plugs - Set of 4

Sold in sets of 4. 

NGK Laser Iridium spark plugs feature laser-welded technology. Lasers are used to pinpoint precision welds, reducing excess debris; this decreases the required voltage to bridge the spark gap. An iridium disc is welded on the center electrode and a platinum disc is welded on the ground electrode, reducing the wear rate of both surfaces and ensuring great durability and long life. These spark plugs are available for use with a variety of engine types. 

Manufacturer heat range:  7  The Denso ITV24 race plugs are one step colder than this plug. 

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

These work in LNF, LHU, & LTG

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