Supertech Honda K Series 86.00mm Bore +11.4cc Dome 12.5:1 CR Pistons - Set of 4 (Excl Rings)

These Supertech pistons are forged from high-strength aluminum, a common choice for performance builds because it offers a good balance of strength and weight. Each piston features a +11.4cc dome volume, which, when combined with the 86.00mm bore size, helps achieve a 12.5:1 compression ratio. This higher compression ratio is designed to increase power output and improve throttle response, especially when paired with performance camshafts and tuning.

The set includes four pistons, but remember that the piston rings are sold separately, so you'll need to account for that when ordering. Supertech is known for making well-built internal engine components, and these pistons are no exception. They are intended for K-series Honda engines where a significant increase in performance is desired. Because these are a performance part, proper engine management and supporting modifications are crucial for optimal results and engine longevity.

When rebuilding or upgrading your K-series engine, choosing the right pistons is critical. These Supertech pistons offer a solid option for those looking to push their engine's performance envelope. Be aware that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
