Accel Shorty Copper Spark Plug

This is an 8-pack of Accel Shorty Copper core resistor spark plugs with a 14mm thread and 0.46-inch reach with projected tip, 5/8 Hex, and a tapered seat. ACCELs Shorty spark plugs keep your spark plug boots from being burned and your headers from being dented if you dont have enough room between your plug boots and your exhaust manifold or headers. Designed for trouble-free installation and removal in cramped spaces, these high-performance plugs are much 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. Youll have instant throttle response and better fuel economy with less fouling, flame dissipation, and misfire. These copper-core plugs provide increased thermal conductivity.
