Mahle MS Piston Set Honda/Acura K24 87.5mm Bore 99mm Stroke 152mm Rod -9.4cc 10 CR Set of 4

These Mahle MS pistons are built from 2618 aluminum alloy, a strong material chosen for its ability to handle high temperatures and pressures found in performance engines. With a bore of 87.5mm and a compression ratio of 10.0:1, they are specifically designed to work with the K24 engine, featuring a 99mm stroke and a 152mm rod length. The -9.4cc dish volume is key to achieving that 10.0 CR, balancing power with pump gas compatibility for many builds.

Each piston weighs in at 318 grams, a carefully managed weight that contributes to the engine's ability to rev freely without sacrificing strength. The 22mm pin size is standard for many performance applications, ensuring good compatibility with aftermarket connecting rods. Mahle's reputation for well-built engine components means you're getting a set that's ready for demanding use, whether you're rebuilding a street car or a track-focused machine.

This set includes four pistons, ready for installation. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
