The Aeroflow Performance ignition coil-on-plug plug with pins are designed to suit AF4020-8299 R35 GTR hitachi style coil. These are a great solution when re wiring the car for a fresh start or you wish to make new extension harnesses yourself when installing them coil packs in OE or aftermarket applications. Over time with heat these plugs can become brittle and break apart so it's a great idea to replace them to avoid any unwanted misfiring issues.
