What is the primary benefit of the L-Comp designation on these pistons?

The L-Comp (Lower Compression) designation means these pistons are designed for engines that will use forced induction, such as turbochargers or superchargers. This lower compression ratio allows for higher boost levels without causing detonation or pre-ignition.

What does the 'S3 D88' specification refer to?

The 'S3' refers to the specific compression ratio and dome shape engineered by HKS for this piston set, tailored for the G16E engine. 'D88' indicates the precise diameter of the piston, ensuring it fits correctly within the cylinder bore.

Are these pistons suitable for a naturally aspirated engine build?

While these pistons are well-built, the L-Comp designation is generally intended for forced induction applications. For a naturally aspirated build, a higher compression piston might be more suitable to maximize power output without boost.

Product Details

Forged from high-strength aluminum alloy, these HKS BCD pistons are built for serious engine builds where reliability and performance are paramount. The S3 design features a specific compression ratio and dome shape, carefully calculated to work with the G16E engine's 1.75-liter displacement. This kit is designed for enthusiasts looking to push their engine's capabilities beyond stock, offering a solid foundation for a high-performance powerplant.

The L-Comp designation indicates a lower compression ratio, which is often chosen when planning to use forced induction like turbochargers or superchargers. This allows for more boost pressure without encountering detonation or pre-ignition, giving you more tuning flexibility. The D88 specification refers to the piston diameter, ensuring a precise fit within the cylinder bore. HKS is known for its attention to detail in engine components, and this piston set reflects that commitment to quality and performance engineering.

When undertaking a performance engine build, selecting the right internal components is crucial. These HKS pistons are a well-built option for those aiming for significant power gains. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always consult with a qualified engine builder or refer to HKS's technical documentation for complete installation guidelines and recommended supporting modifications to achieve your desired performance goals.
