Own a 02-05 Subaru WRX EJ20 and plan on building a motor? Wiseco is proven to make some of the best pistons on the market!
Featuring valve pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized. Piston crown shapes designed to promote maximum intake charge efficiency thru scavenging mixture "cross flow" during intake and exhaust valve overlap. More fuel and air equals more horsepower!
Their pistons are designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.

These pistons fit perfectly in a 2002 ej205, all pistons were within fractions of a gram of each other. Rings also came sized perfectly for the engine. Overall great product and great, timely shipping from map performance! As for the performance of the engine, we will see how it goes however I dont think these pistons would be the point of failure if something goes wrong.
