The ignition system of a Jeep Wrangler JK ignites a mixture of gas and fuel that is used to power the engine. The better the system, the more efficient the vehicle will be. This goes double when you take your Wrangler off-road where challenging terrain and natural obstacles force the engine to work harder. A superior JK ignition system can lower vehicle emissions and improve throttle response and gas mileage. It accomplishes this by increasing the energy that is delivered to the spark plugs. When you take your Wrangler off-road you are going to need a battery tray that can support the turbulence from tough terrain, as well as an alternator that can handle the added power usage. Whatever your needs, ExtremeTerrain offers a large selection of ignition system components to match your needs.
