JE Pistons RENAULT CLIO RS F4R 12.8:1 Set of 4 Pistons

If you're rebuilding the engine in your Renault Clio RS F4R for serious performance, a set of JE Pistons is a solid choice. These aren't just off-the-shelf parts; JE Pistons has been making forged racing pistons for over 75 years, and they've applied that experience to create pistons specifically for demanding applications like yours. They're engineered to handle the stress and heat that come with pushing your F4R engine hard, whether that's on the track or just for spirited driving.

What sets these pistons apart is how they're made and the design features they incorporate. Forged from 2618 aluminum right here in the USA, they offer the high tensile strength needed for high-demand performance. You'll find JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight too. Depending on the specific application, you might also get an accumulator groove to help manage combustion gas pressure, improving ring seal and keeping power consistent. Some applications also feature a skirt coating that further reduces friction and wear on the cylinder walls, which can also quiet down the engine's operation.

This set includes everything you need to get your F4R's short block assembled: four pistons, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. They're designed specifically for the F4R engine and a 12.8:1 compression ratio, aiming for optimized performance and durability. Just remember, these pistons are not CARB approved and cannot be shipped to California.
