Custom Performance Engineering MagnumDI™ 2015-2021 Ford Mustang EcoBoost Stage 2 Pistons-Stock Bore

Custom Performance Engineering continues its Ford EcoBoost 2.3L Turbo development and pushing the limits of technology. They are proud to introduce the MagnumDI™ Stage 2 EcoBoost 2.3 Pistons. Additionally, these are the perfect choice for your built Focus RS or Ecostang. 

These pistons are track tested with countless passes on the world’s first 9 second EcoBoost vehicle. Custom Performance Engineering has gone through several revisions and settled on a design. Additionally, that design is proven to take hard use and abuse over and over again. They have also tuned these pistons on the track and they are ready to stand up to daily and track use. 

Stage 2 EcoBoost 2.3 Pistons 

Custom Performance Engineering has set out to design pistons with performance and strength in mind specifically for the Ford EcoBoost 2.3L Turbo motor. Basically these Stage 2 pistons will hold up to almost anything. Made using a state-of-the-art forging process with extensive heat treating and special finishing, cp-e™ ensures optimum reliability which is exactly what is needed in a high-performance engine. 

These pistons are precision machines to cp-e™ spec. Additionally, their Stage 2 pistons have specifically designed valve pockets and a dome with unique features. This optimizes fuel distribution within the cylinder. The extra pocket in the dome design sends fuel up towards the spark plug, optimizing the mix with oxygen and in turn making the burn process more efficient. 

EcoBoost 2.3 Pistons Build Quality 

They machine the pistons with a special cam and barrel design that helps with piston positioning within the cylinder and its movement with stress and heat. This also reduces the noise, commonly acquired with forged internals. All of their Stage 2 pistons feature a coating that reduces friction and noise, while promoting oil lubrication. 

cp-e™ knows the Ford EcoBoost 2.3L Turbo inside and out. And has done extensive research and engineering to bring you the proper tools for a successful, high horsepower solution. The MagnumDI™ Stage 2 pistons are the choice for reliable power.
