WOSSNER FORGED PISTONS AND RODS FOR THE 2.3 ECOBOOST FOCUS RS/MUSTANG ECOBOOST

The Focus RS and Mustang EcoBoost engine has a weak point and many customers that have pushed the car to the limits have found the issue with the stock pistons. For all customers wishing to push the car to the limit the piston and rod upgrade are essential.

The pistons have been based around OEM samples supplied by Ford Performance and tweaked to make them more suitable for aftermarket tuning. The main change is the slight drop in compression ratio over OEM pistons. The 2.3 engine uses Ford’s Eco-Boost direct injection system which makes changes to the compression ratio difficult. Too high will result in detonation and the subsequent “dialling back” of the ignition advance dulling performance, and too low will end up with poor fuel economy and emissions unable to pass yearly checks. We have listened to the feedback from a number of sources regarding our existing 2.0, 1.6 and 1.0 Ecoboost pistons and decided to lower the C/R on these pistons from the OEM 9.3:1 to 9.0:1. A minor drop but should provide a useable C/R for tuning without the adverse effects mentioned above.

You can also purchase the pistons and rods separately by navigating to the Focus RS Mk3 portion of our website, and scrolling down to "Engine Build"
