Pred 558 question

[Chris525]

my buddy is boring his 05 pred 500 to a 558
the kit come piston, rings, gaskets, and sleeve
he is going to get k&n intake and jet kit
is there anything else that is MANDATORY to upgrade at this time

nope, not that i know of......an exhaust system would be nice though, or you really aren't going to see any gains of that bigger engine
