Product Details
| Part Number: | COAT-S |
| Brand: | CP Pistons |
| CARB Approved: | No |
The CP Piston Skirt Coating (COAT-S) is a performance-oriented surface treatment designed to enhance the durability and operation of CP Pistons in high-stress engines. This specialized skirt coating adds a protective layer where pistons contact the cylinder walls, helping optimize friction, wear resistance, and overall engine performance.
If you’re building or rebuilding a high-output engine — whether for racing, forced induction, or aggressive street use — improving piston skirt performance is a smart upgrade. The COAT-S treatment from CP Pistons adds a dry film coating to the piston skirt that supports smoother piston travel and reduces wear during initial break-in and beyond.
Features:
Enhanced Skirt Protection
- The COAT-S coating applies a specialized surface treatment to the piston skirt to help protect against abrasion and minimize surface wear where the piston meets the cylinder wall.
Reduced Friction & Smoother Operation
- By creating a low-friction interface between the piston skirt and cylinder surface, the COAT-S treatment promotes smoother movement and improved cold-start performance—especially beneficial in high-RPM or high-load conditions.
Better Early Break-In Behavior
- Skirt coatings like COAT-S can aid during initial engine break-in by helping establish an optimal piston-to-bore interface, which may contribute to longer-term reliability and reduced piston slap.
OEM-Level Fit & Finish
- Designed to work seamlessly with CP Pistons and their precision manufacturing standards, this coating option does not alter piston geometry while delivering proven surface performance benefits.
Who It’s For
- This skirt coating is ideal for engine builders, performance enthusiasts, and tuners who want to extract maximum reliability and efficiency from their CP Pistons — particularly in motorsport, boosted, or high-RPM applications.
