Overview

Upgrade your Subaru WRX with the Manley 93mm +1.0mm 8.5 Platinum Series Dish Piston Set. Designed specifically for the EJ205 2.13L engine from 1998 and onwards, this piston set is engineered to enhance your driving experience while providing durability and performance. Crafted from robust 2618 alloy, these pistons are lightweight yet built to last, ensuring a long service life. The offset wrist pin design promotes quiet start-ups, making your engine run smoother right from the get-go. The unique "one fixturing" method guarantees perfect ring groove to skirt squareness, which translates to maximum horsepower. Each piston comes with moly coated skirts to reduce friction and wear, enhancing overall engine efficiency.
