The Nology PowerCore Ignition Coil Amplifier increases your ignition coil output performance by up to 50%. This hotter, more powerful spark ignites the fuel/air mixture much quicker, more reliably and more efficiently; thus increasing horsepower and torque, whereas fuel consumption and emissions are decreased. PowerCore is absolutely essential for high compression and/or high rpm engines, and all lean-burn applications. PowerCore is the perfect ignition upgrade for vehicles where the ignition coil is incorporated within the distributor, (Honda , Acura, General Motors). Many times a performance coil is not available for those systems. Simply connect the PowerCore amplifier to the stock coil and get up to 50% more spark power (Make sure you are using the correct amplifier, they are not compatible with all vehicles!) The PowerCore Technology: Think of it as a supercharger for the coil. A supercharged engine (same displacement), makes a lot more power. Same is true for the PowerCore coil amplifier. The coil size stays the same, but the energy that is stored in the PowerCore is supplied to the coil, resulting in added spark energy and higher possible spark voltage. Just like the supercharger, who accelerates engine rpm climbing-rate, the PowerCore accelerates coil saturation time. This PowerCore Ignition Coil Amplifier is made for ignition systems without active current limiting and most automotive applications Model Year 1990 and older with 2.5 to 3 Ohm ignition coils.
