75 Years of Forged Piston Leadership

As the leader in forged racing pistons, JE Pistons has applied over 75 years of experience to its wide range of premium forged pistons for European, import, and sport compact applications. Engineered, forged, and machined 100 percent in the USA, JE Pistons are designed for each specific engine and racing application to provide the ultimate combination of durability and performance. This kit is built specifically around an EJ257 with an 83mm stroke, 99.75mm bore, and 8.5:1 compression ratio, rather than a generic piston sized to approximately fit. That's the kind of detail that separates genuine engineering from a basic replacement part.

Proven in Victory Lane, Not Just on Paper

From drift track to drag strip, JE Pistons' performance is proven in victory lane time and time again, a track record that comes from real racing feedback rather than just lab testing. That kind of proven durability matters enormously in a piston, since a piston failure at high RPM or under boost can take the rest of the engine down with it. Equip your engine with the best in forged pistons for a build that needs to hold up to real abuse. It's a small distinction that makes a real difference once you're actually building the engine.

Straight From Subispeed

A genuinely race-proven forged piston kit for 2008 Forester / 2002-2012 WRX / 2004-2012 STI / 2010-2011 Legacy, built to exact application-specific dimensions rather than a generic size.
