More about this item : Shorty ACCEL 0437S-4 Copper Core Spark Plug, (Pack of 4)

ACCEL's spark plugs, known as 'Shorty', keep your spark plug boots from being burned and your headers from being dented if there is not enough room between your plug boots and your exhaust manifold or headers.

Designed for installation and removal in cramped spaces, these high-performance plugs are easier than OE plugs to get a socket on but still deliver a larger, hotter, fuller flash front and significantly more power at high rpm.

You'll have throttle response that is instant and better fuel economy with less fouling, flame dissipation, and misfire.

These plugs with a copper core provide increased thermal conductivity, come with machine-rolled 14mm threads to protect your heads, use a standard 5/8 socket, and are available in a pack of four.
