CP has taken Forged Pistons to a new level... in all of our 40+ years building high performance engines, with many piston manufacturers and every type of engine, all we can say is "Wow!"

At VAC, we feel that these are the best bar-none for your high performance or race engine.
Working closely with CP, their BMW pistons meet our most stringent expectations and are the finest available anywhere. This is why we now chose to offer them for the popular Japanese applications.

We can provide a variety of compression ratios and bore sizes direct from CP and can also supply you with any custom piston application quickly. Please call for 20V pistons.

Don't get caught up in hype of JDM brands; CP pistons are made in the USA and are chosen by the fastest engine builders and race teams around the world. We would put them up against anything, and we do when our engines power winning cars.
