Mahle Forged Pistons TBC Coated MR2 SW20 Celica AllTrac 3SGTE Gen 2 / 3 86.5mm +0.5mm -4.1 cc 9.0:1

Mahle's PowerPak piston assemblies include forged pistons, piston rings, pins, and wire locks--all in one race-proven package. The pistons are hand-deburred and then coated with dry phosphate to protect against ring micro-welding and pin galling during initial startup. For additional performance, Mahle added its proprietary Grafal anti-friction coating to the piston skirts. Low drag rings, steel pins, and round wire locks complete the Mahle PowerPak package.

MAHLE Motorsport Ceramic Thermal Barrier Coating

MAHLE Motorsport now offers a proprietary thermal barrier coating application for the PowerPak performance forged pistons. This ceramic-based thermal application greatly reduces heat transfer for improved performance and adds a layer of insulation to the piston crown to protect against thermal shock. For added protection and performance, this cutting edge thermal coating is particularly important for use on the crown to prevent hot spots.

Thermal Barrier Coating was developed by MAHLE Motorsport to create more protection for the piston crown as demands for piston and engine component performance have increased in multiple forms of motorsport. Designed primarily for improved engine efficiency in race engines that need increased torque and HP.

Features:

• Greatly reduces heat transfer
• Improves performance
• Adds a layer of insulation to the piston crown to protect against thermal shock
