If you are building your motor to sustain high levels of boost, then a quality set of forged pistons should always be on the shopping list. These are the Manley Platinum Series Pistons and feature durable forged construction. The factory pistons are known to break the ring lands after a certain power level, and like all stock pistons, they are limited after a certain power level.

Manley's Platinum Series Forged Pistons are built to sustain higher power levels or to sustain prolonged high-RPM use such as a weekend track event. They will come supplied with new piston rings and new wrist pins, and make for an excellent piston choice for your dedicated race car, rally car, or high-powered street car.
