Manley Extreme Duty Platinum Series Pistons 99.5mm Bore 8.5:1 CR | 2004-2020 Subaru EJ25 (632200CE-4)

EJ25 - PLATINUM SERIES TURBO TUFF PISTONS

The best aftermarket Subaru piston company just got even better with our new Turbo Tuff lineup targeted specifically for EJ25 engines. By incorporating proven design enhancements from our "Formula-Won" piston forging, we've created the ultimate Subi piston to withstand the rigors of the highest boosted and stressed applications yet still run "quietly" and trouble-free for the daily driver. Like all Manley Subaru pistons, these are made from 2618 alloy, utilize an offset wrist pin design, are skirt coated and include our 9310 alloy .250" wall wrist pins.

Premium steel top rings with Napier style second rings and higher tension oil rings for ultimate oil control are included with each set along with round wire locks. Recommended clearance: .003" for mildly boosted and .0035" for highly boosted measured .850" (79/83mm Strokes) and 1.100" (75mm Stroke) from the bottom of the oil ring groove.
