Details:

The piston is the weak link in the stock WRX/STI block. These are great for someone either reassembling their block or someone looking to put in some strong pistons in their "built" block. 

Throw these forged high strength aluminum pistons in and turn up the boost and get more power from your WRX/STI! These CP pistons have been put through rigorous testing. In short, they are built to withstand nearly whatever you can throw at em'!
