Manley Platinum Series Forged Piston Set Bore Subaru

Manley Platinum Series forged pistons are made for Subaru engines that see higher boost, higher RPM and more power than the factory pistons were designed for. They are machined from high-strength 2618 aluminum forgings. This gives a strong, lightweight piston for turbocharged street, rally, track and race builds.

Key Features:

• 2618 forged construction: a good balance of strength and low weight, with long service life.
• Offset wrist pin design: helps keep cold start-ups quiet.
• "One fixturing" machining: Manley's process aims for precise ring groove to skirt squareness, which supports consistent ring seal and power.
• Skirt coating: helps reduce friction and wear.
• Pressure balance groove: found on select applications.
• Hardware: premium steel top ring sets, chrome moly wrist pins and round wire locks are supplied with Platinum Series kits.
• Drop-in design: made to replace the factory pistons in a stock-style Subaru engine build.

Factory cast pistons can fail at the ring lands under heavy boost. Manley Platinum Series forged pistons give engine builders a stronger option for rebuilds and performance upgrades. Choose the bore size, compression ratio and piston type that match your engine and build plan.
