Product Description
This is a forged piston set manufactured by Omega Pistons for the EJ22G engine, as used in the Subaru Impreza 22B built between March and August 1998 (V3-V4).
Pistons are forged rather than machined from a solid billet, which Omega state gives a more consistent grain structure and added strength for high-load use. Each piston is individually weighed and batched, with a manufacturer-stated tolerance of within 0.5g per piston and no more than 2.0g deviation across a set of four.
Supplied in 0.25mm and 0.50mm oversize only (no standard-bore option listed). Listed for GC/GF-chassis Subaru Impreza (1992-2000).
