Check the listing for details. ACCEL 0416S-4 HP Copper Spark Plug - Shorty. Condition: New. Listed at 47.13 USD. The overall length has been reduced 3/16 in to 3/8 in (depending on the specific spark plug) to gain critical air gap between the spark plug boot and the exhaust manifold or header tube. The shorter spark plug length also can make it easier to install an remove the spark plugs in certain applications where there is not a lot of room to fit a socket or move a wrench around.
