The kit comes with a sparkplug, a bong for the plug that you have to drill a hole for in your pipe about 6 inches from the tip, a switch and a box that you wire into the ignition. you have to buy a coil and coil wire. what it does is enterupts (spelling) the firing of the plugs of the ignition so as to send more fuel through the exhaust to ignite. when you hit the switch it ignites the plug in the exhaust and stops the firing in the engine momentarily. hope that isn't to confusing. pretty simple, and i would imagine that you would be able to build one yourself, they did it on the old hotrods. it is one of those things that you don't see much of anymore and really gets peoples attention when you throw the flames. haha.
