Frequently Asked Questions
Upgrade your all motor engine build with the SpeedFactory Racing B20 Type R Race Spec High Compression Piston Kit, engineered to deliver superior performance and reliability for your high compression all motor build.
These pistons utilize AC9B hypereutectic aluminum alloy for greater strength plus scuff and seizure resistance with improved groove wear and durability. The top land has been enlarged for more strength and resistance to breakage. They also allow tighter piston-to-wall clearances for reduced piston rocking resulting in better ring seal and more power all while being lightweight.
Compatible with OEM rods as well as aftermarket forged rods and include Moly skirt coating that helps minimize friction preventing scuffing and wear, providing increased piston life & efficiency.
