Manley has recently released their Turbo Tuff pistons lineup targeted specifically for EJ25 engines. By incorporating proven design enhancements from their "Formula-Won" piston forging, they've created the ultimate Subaru 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 a standard 2.500" x .180" wall premium chrome moly wrist pin (P/N 42346). 9310 alloy .210" wall pin upgrades are available. Simply order the EXTREME DUTY part number in the column below. These come equipped with the 9310 pins (P/N 42546). 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 1.100" from the bottom of the oil ring groove.Manley Subaru EJ257 pistons now include Napier style second rings and higher tension oil rings (by Total Seal) for superior oil control.

Jonny pistons are top notch, used them before with an evo build and was not disappointed.
Install was perfect, looks great installed with k1 rods and ej207 crank.
Gaping piston rings were as fun as ever measure twice and file once, never disappointing with the total seal rings that come with the pistons
