Leave it to Mahle to create a true DROP-IN, forged race ready piston for the Honda H22. You know the problem. Reinforced matrix cylinder bores always require sleeving the block first. Well welcome to easy street. Mahle's proprietary skirt coating allows the piston to work perfectly without sleeving the block!
All aftermarket H22 Pistons (Except these Mahle Gold Series) are designed for use with aftermarket sleeves. Wiseco/JE/CP and many others are not designed to be used with standard block H22 engines. These Mahle Gold Series Pistons are made of a Low Expansion 4032 Aluminum Alloy that allows it to be used in the H22's standard fiber reinforced sleeves.
Specifications:
- Set of 4 pistons
- Including piston rings and wrist pins/clips
- Compression Ratio: 12.0:1
- Bore: 87.00mm
