CP Piston & Ring Set for Honda L15A VTEC - Bore (73.0mm) - Size (STD) - Compression Ratio (11.5)

Forged from 2618 aluminum alloy, these CP Pistons are built for demanding performance applications where strength and reliability are paramount. This set is specifically sized for the Honda L15A VTEC engine, featuring a 73.0mm bore and standard (STD) sizing, ensuring a precise fit for your rebuild. The 11.5:1 compression ratio is an updated figure from stock, designed to extract more power from your engine when paired with appropriate tuning and supporting modifications.

The 2618 aluminum alloy offers excellent strength and fatigue resistance, making these pistons a solid choice for boosted or high-revving setups. CP Pistons includes a complete ring set with this package, simplifying your build process. Each piston is designed with specific skirt profiles and crown shapes to optimize combustion and reduce friction, contributing to improved engine efficiency and power output. The standard bore size means these are intended for engines that are either new or have been machined back to factory cylinder dimensions.

When undertaking a performance engine build for your Honda L15A VTEC, using well-built internal components like these forged pistons is crucial. They are designed to withstand higher cylinder pressures and temperatures than cast pistons. Remember that any modification to the compression ratio will require proper ECU tuning to take full advantage of the changes and ensure engine longevity.
