TR55 Plug - Stock heat range, gapped at .060".

These V-Power plugs from NGK use a 90 degree V-shaped center electrode that directs the spark to the edge of the electrode. This prevents the spark from being absorbed, or quenched, and allows it to develop faster. That hotter spark means better combustion, which improves performance and creates less harmful emissions. V-Power spark plugs also require lower ignition firing voltage, resulting in quicker starts and easier cold weather starts throughout the life of the plugs.

Sold in boxes of 4 plugs.
