About this part

Product Details

JE Pistons' Ultra Series pistons start with a unique Aligned Grain Flow forging process, a proprietary method that maximizes tensile strength. This is crucial for handling the intense cylinder pressures you'll encounter in high-boost, power-adder engine builds, especially for your Subaru FA20. These aren't just basic pistons; they come loaded with features you'd typically only find in custom setups.

You'll find a ceramic-based thermal barrier crown coating that reflects heat back into the combustion chamber, helping to keep piston crown temperatures down and improving how efficiently exhaust gases are scavenged. The skirts are coated to reduce friction and wear against the cylinder walls, which also helps quiet things down, particularly during a cold start. To ensure everything stays well-lubricated under extreme conditions, these pistons have optimized pin oiling features, keeping the wrist pins and bores slick. Plus, lateral gas ports are included to help maintain a solid seal on the top compression ring, even when you're pushing high RPMs and serious boost.

This set includes high-strength, thick-wall wrist pins made by Trend Performance in the USA, built to handle the rigors of performance builds. Every aspect of these Ultra Series pistons is optimized for high-horsepower racing engines, and the entire set is manufactured 100% in the USA. Keep in mind these are not CARB approved and cannot be shipped to California.
