Description
This Platinum Series piston family targets 2003-2006 Evo 8/9 (7 Bolt 4G63T) 85.5mm +.5mm Over Bore engine combinations and should be selected from the finished-bore specification rather than from vehicle fitment alone. The parent listing is distinguished by 100mm / 8.5:1, which should be cross-checked against the rest of the engine combination.
Because this is a 2003-2006 Evo 8/9 (7 Bolt 4G63T) 85.5mm +.5mm Over Bore piston family, final fitment depends on the machine shop’s finished cylinder measurement and the intended rod/stroke combination—not simply on nominal engine displacement.
