In a high-performance engine, power is key. Many aftermarket parts can add power to your engine, but reliability can come from the right distributor. The distributor is responsible for sending a spark to your cylinders. A performance distributor provides more regular voltage to your spark plugs, meaning a stronger and more consistent spark for your engine. This creates better fuel mileage, more power, and a smoother-running engine. Many of our performance distributors are also adjustable to tailor the timing and spark advance to your performance vehicle. At O'Reilly Auto Parts, we have a variety of performance parts in stock. Take a look and find the right distributor upgrade for your vehicle.
