Highly boosted, direct injection engines,
such as GM’s LNF 2.0 require strict adherence
to the original dome and bowl design
to maintain proper combustion characteristics.
Wiseco’s new K635 series piston is
the only forged piston utilizing special form
tooling for the correctly shaped dome and
bowl design. Coupled with Wiseco’s brush
dome deburring, Nitrde steel XX rings, skirt
coatings, and extra stout 5mm wall
thickness pins (offset like the OE for noise
reduction), this is the only forged piston with
the technology needed to properly
compliment D.I.
