JE forged piston set for 4.6 4V Modular engines. Specified for an 8.5:1 compression ratio, this set of eight shows a 3.572 in bore with 1.200 CD and -21.0 cc. JE’s Forged Side Relief design lowers skirt friction and weight; accumulator grooves and skirt coatings—if included—enhance ring control and reduce wear.
