In order to fully understand how the latest in speed parts work, you first need to understand how an engine works. Most cars as we know them are powered by what is called a 4-stroke engine. A 4-stroke refers to the four strokes in the power cycle; the intake stroke, the compression stroke, the power stroke and the exhaust stroke. We will cover thes...
