For track use we recommend more aggressive cam (maximum valve lift (tdc) of 2.1 mm) . Piston's have very deep pockets for use with sport valves. These are 107 mm in size so are slip fit and do not require modifications. This kit is ideal for track use but can also be used on the street, it will add 40+ hp (depending on your additional modifications). Mahle pistons are forged for substantially higher and more uniform strength over pistons that are cast. Mahle cylinders are manufactured from st52 steel which has extremely high thermal resistance, they are nikasil coated which reduces wear and friction.

Make a selection 10698689 Our nickies™ kits for Boxster & Cayman models includes custom forged side relief je pistons, including coated skirts, split oil returns, quench pads, and accumulator grooves, just like the factory pistons. This allows for faster burn and better thermal efficiency, leading to better gas mileage, lower potential for detonation, and more power by retaining the factory inverted dome piston shape, mirroring the pent-roof four-valve combustion chamber! Forged pistons are superior to the factory cast pistons found in non-”s” model engines and are as strong as the forged pistons found on “s” engines, but use a lightweight forged side relief design for improved strength while being lighter than the factory pis...(choose a part on the right to read more) General FitmentBOXSTER 1997-04BOXSTER 2005-08 CAYMAN 2006-08
