Wiseco Professional Series Forged Piston Kit for Acura 4v (+5cc Dome, Strutted, 81.0mm) - K566M81AP
$831.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select Acura 4V engines with an 81.0mm bore size. Engineered for serious racing and heavy-duty engine builds.
Wiseco Professional Series pistons are forged and machined in the USA from high-strength 2618 aluminum alloy, offering the superior tensile strength necessary for severe-duty applications. This kit features a strutted forging design for maximum rigidity and weight optimization, allowing the rotating assembly to withstand high cylinder pressures. The pistons are treated with proprietary ArmorGlide skirt coating to reduce friction, minimize noise, and prevent scuffing or seizure during high-stress operation.
To ensure long-term reliability, these pistons include forced pin oiling for consistent wrist pin lubrication and anti-detonation grooves to maintain ring seal integrity. Each crown is fully machined for precise compression control and valve clearance.
