Forged Piston Sets - 4-Cylinder Engines

Forged piston sets for 4-cylinder engines are the most popular piston upgrade in the performance market, serving the massive community of turbocharged and naturally aspirated 4-cylinder builds. Forged from 2618 or 4032 aluminum alloys, these pistons handle the elevated cylinder pressures of boost, nitrous, and high compression that crack factory cast pistons.

OneFastShop carries a wide selection of forged piston sets for 4-cylinder engines including dome, dish, and flat-top designs, multiple compression ratio options, complete piston-and-ring kits, and application-specific sets for Honda B-Series, K-Series, Subaru EJ/FA, Mitsubishi 4G63/4B11, Nissan SR20, Toyota 3SGTE, Mazda MZR, Ford EcoBoost, and many more popular 4-cylinder platforms.

Every 4-cylinder piston set at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're building a daily-driven turbo setup, an all-out drag car, or a high-revving naturally aspirated screamer, OneFastShop has the 4-cylinder pistons for your build. Shop the full 4-cylinder forged piston sets collection today.
