Each system comes with a free-flowing muffler to keep the exhaust gases moving, so the EcoBoost’s turbo can cram more power-building air into the engine. Both Diamond Eye Performance and aFe Power make high-quality stainless steel systems to get the job done right-and add a more aggressive performance sound, too. We recommend swapping out your stock exhaust system with a larger diameter, mandrel-bent exhaust system to reduce exhaust restriction. Building on the technology outlined above, here are some popular upgrades that will help you maximize the performance of your 3.5L EcoBoost engine: EcoBoost Upgrades Cat-Back ExhaustĪs with any engine, you can make room for an even bigger intake charge by getting rid of the exhaust gases within the engine more quickly. Still, as motorheads and performance enthusiasts, we’re always wanting more. Using the greater air volume from the turbocharger and increased fuel efficiency from direct injection, the EcoBoost engine creates power on par with larger, naturally aspirated engines while achieving much better fuel economy. Plus, the pin-point fuel delivery of the direct injection design fosters a reduced amount of “greenhouse emissions.” The combination of turbocharging and direct injection results in more airflow and pin-point fuel delivery. Each one of these engines incorporates a common set of characteristics: turbocharging and direct injection. Popular sizes include the 3.5L V6, 2.3L V6, 2.7L V6, and 1.6L I4. Introduced for the 2011 model year, the EcoBoost family of engines comes in a variety of four- and six-cylinder sizes (and even three-cylinder) and is available on everything from the compact Focus to the workhorse F-150. To understand why these upgrades are effective, you have to first understand how EcoBoost technology works. We’ve compiled a list of some of the more-popular upgrades for the Ford EcoBoost family of engines, using the flagship 3.5L EcoBoost as our example.
Not surprisingly, there are ways to achieve even more power and efficiency from your EcoBoost thanks to a variety of aftermarket parts options. The EcoBoost got its name from the improved fuel economy and efficiency of its direct-injection design and the boost from the turbocharger that’s central to these engines.
