These distributors come complete and ready-to-run. All you need to do is drop it in the engine, connect three wires and fire the engine. Each distributor features an ignition module that produces a powerful inductive spark to improve combustion of the fuel mixture resulting in quick starts, smooth idle and increased performance.<br><br>The billet aluminum housings of these distributors are 5/8 in. smaller in diameter to accommodate induction setups and tight engine compartments. A maintenance-free magnetic pickup is responsible for reluctoring the high voltage sparks while a sealed ball bearing guides an oversized shaft.<br><br>Beneath the bolt down cap and MSD race rotor you'll find MSD's accurate mechanical advance assembly.
