Manley piston set for Subaru 2.5L EJ257 (WRX/STi) with a 99.50mm bore, 1.130in compression height and -14.00cc crown volume. These "Platinum Series" forged pistons utilize domestic 2618 alloy forgings and cam-and-barrel skirt profiles to support power while being gentle on cylinder walls. Tool steel wrist pins and moly skirt coatings on select SKUs, together with precise ring lands and grooves, help maintain strong ring seal for tuned engines.
