P4-HK87-N0 SUPERTECH Pistons Head Compression Honda

Review SUPERTECH Honda K24 Series Pistons K20 Head 87mm Bore 11.5 Compression for HONDA

Introducing the Supertech P4-HK87-N0 pistons, a high-performance upgrade for your Honda K24 engine or K20 head with a bore size of 87mm and a compression ratio of 11.5:1. These pistons are meticulously engineered to deliver increased power, improved efficiency, and enhanced durability compared to OEM pistons.

Each piston is made from forged 2618-T6 aluminum alloy, ensuring exceptional strength and rigidity. The top ring groove is designed to accommodate a 2-piece ring set for better sealing and reduced engine blowby. The piston skirts feature an optimized shape and surface finish, allowing for a perfect fit in the cylinder bore and reducing friction for smoother engine operation.

The Supertech P4-HK87-N0 pistons also come with a unique, high-tensile, coated piston pin, which provides excellent strength and durability under high loads. This piston pin is also designed with a floating wrist pin, allowing for greater piston-to-liner clearance and reduced friction.

Moreover, the piston crown is designed with a dish shape for improved combustion efficiency and increased power output. The piston crown also features a polished, mirror-like finish, which reduces friction and helps the piston slide more smoothly in the cylinder bore.

These pistons are also designed with a thin-walled, low-mass design, which helps to reduce the overall weight of the piston assembly. This results in faster engine response and improved throttle sensitivity.

In summary, the Supertech P4-HK87-N0 pistons are a high-performance upgrade for your Honda K24 engine or K20 head. They are meticulously engineered to deliver increased power, improved efficiency, and enhanced durability compared to OEM pistons. Each piston is made from forged 2618-T6 aluminum alloy, features a coated piston pin with a floating wrist pin, and has a dish-shaped piston crown with a polished finish. With their thin-walled, low-mass design, these pistons help to reduce engine weight, improve response, and enhance overall performance.

Supertech P4-HK87-N0 pistons are aftermarket pistons designed for use with Honda K24 engines and K20 heads that have an 87mm bore and 11.5:1 compression ratio. These pistons offer several potential benefits and drawbacks for engine builders and performance enthusiasts.
