PowerAid GM 8.1-liter Big Block Throttle Body SpacerThe newest GM LS-1 PowerAid 1-inch Throttle Body Spacer features a unique and patented Helix Bore-design which creates a vortex action of the incoming air charge as it passes through the throttle body spacer. This highly-active air charge contributes to better atomization of the air/fuel mixture at the combustion chamber. The end result is more throttle torque, improved mid-range power, and overall combustion efficiency for additional fuel economy.

MSD 8.5mm Super-Conductor Spark-Plug WiresThere are two main objectives of a spark-plug wire: to transfer the spark energy and to suppress the electro-magnetic interference (EMI) that the spark voltage projects. Too high a resistance decreases the spark energy, yet too low a resistance may generate too much EMI noise, which will interfere with other electronics on the vehicle. The Super Conductor Wire has fewer than 50 ohms per foot compared to a truck's factory wire, which may be as high as several thousand ohms. A special copper-alloy conductor is wrapped very tightly around a ferro-magnetic-impregnated center core, which gives the wire extremely high EMI suppression. This design ensures that optimum spark energy will reach the spark plugs while EMI noise is held at a minimum.
