CP Piston & Ring Set for Honda L15A VTEC (Fit/Jazz)- Bore 73.5 mm - Size +0.5mm - CR 11.5 - Set of 4

If you're rebuilding the engine in your Honda Fit or Jazz with the L15A VTEC engine, this CP Pistons forged piston and ring set is built for performance. This set is designed to replace your stock pistons with a stronger, more durable forged aluminum option, specifically sized at 73.5mm with a +0.5mm oversize to account for machining or wear. The 11.5:1 compression ratio is an updated figure from stock, designed to work with performance tuning for improved power output.

CP Pistons are well-known in the performance engine building world for their robust construction. These pistons are forged from high-quality aluminum, which offers a better strength-to-weight ratio than cast pistons, making them more resistant to detonation and the higher stresses of performance applications. This set includes the necessary rings, ensuring you have a complete package for installation. The +0.5mm oversize means these are intended for engines that have been bored out to match this specific dimension, typically during an engine rebuild where the cylinder walls have been machined.

When installing these pistons, it's crucial to follow the manufacturer's recommended clearances and lubrication procedures. Because these are a performance part with an updated compression ratio, they are best paired with an engine management system that can be tuned to take advantage of the increased compression. This set is not CARB approved and cannot be shipped to California.
