Kenne Bell, The Innovators, has done it again! The FIRST high energy non CD system designed specifically for the new 4, 6, 8, 10 and 12 cylinder engines. And it's cockpit adjustable from 0-50% to handle any boost or rpm. You are in total control. The revolutionary adjustable Kenne Bell BOOST-A-SPARK_ merely taps in on one (1) wire and supplies all the energy your engine needs. All stock modern day engines have great ignition systems for start up, idle, part throttle, fuel economy etc. It's at WIDE OPEN THROTTLE where they're marginal. We activate our hot ignition only where it's really needed - at wide open throttle or in boost. In fact, it produces so much energy you may have to turn it down if the plug wires aren't in good shape. And it works equally well on ALL engines, not just the coil engines.
