Description


EJ25 - PLATINUM SERIES TURBO TUFF GRADE A PISTON

(Sold as -1 individual piston, not sets.)


These pistons feature skirt diameters that correspond to the OEM Grade A or B bores resulting in a piston to wall clearance range of .0023" - .0031".

Please check the bore grades on the top of your block and order the appropriate quantities of Grade A or B 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 standard 2.500" x .180" wall premium chrome moly wrist pin (P/N 42346). 9310 alloy .250" wall pin upgrades are available.


Manley Subaru EJ257 pistons now include Napier style second rings and higher tension oil rings (by Total Seal) for superior oil control.

  • 2618 high strength material
  • Offset wrist pin for quiet start-ups
  • 2.500” x .180” wall Premium Chrome Moly pin (Standard Series) included P/N 42346
  • Pressure balance groove
  • Will accommodate +1mm valve sizes
  • Premium Steel top rings with Napier seconds and round wire locks included
  • Recommended piston clearance: .003” for mildly boosted and .0035” for highly boosted measured .850” (79/83mm stroke) and 1.100” (75mm stroke) from the bottom of the oil ring
