The enhanced piston and connecting rod correspond to the high supercharging pressure and output for the S07A engine.

BCD PISTON + CONROD KIT

The surface has the same crown shape as the OEM one.

Achieve balance between lightweight and rigidity thanks to a bridge structure.

Piston Kit

• It achieves lightweight by allowing the wall thinner by adopting the A2618 material with high-temperature strength.
• The lightweight comes from eliminating waste material by billet manufacturing.
• Rigidity has been structurally improved by adopting the bridge structure. As a result, the product achieves a perfect balance between lightweight and rigidity.
• The crown-shaped surface has the same shape as the OEM one.
• It also achieves improved anti-seizure properties and reduced friction by adopting a 2-layer coating.

Connecting Rod

• Billet chrome steel I-beam connecting rod. It increased the strength by approximately 74% against the OEM product.
• Applying the WPC treatment on the surface to improve the fatigue strength.

Attention: 
Vertical vibration has been increased a little due to the weight being different between the OEM and HKS products.

■Specification

* It is possible to change the compression ratio by using the HKS metal head gasket (sold separately).
