More EGR Coolers for Ford EcoBoost Engines A few months back we took a look under the hood of the 2019 Ford Ranger and found something that appeared to be a bit out of place. It appears that Ford Engineers found that the mid-size truck’s 2.3L EcoBoost engine required an EGR Cooler in order to meet modern emissions regulations. Turns out that EGR Coolers are finding their way onto all sorts of new Ford engines. Recently, we were taking a look at a 2020 F-150 equipped with the 2.7L EcoBoost and tuned by 5-Star tuning. While it was an awesome little ride, we couldn’t help but notice that Ford had snuck an EGR Cooler under the hood. It appears that these direct-injected turbo engines may be a bit dirtier than their “Eco” name would lead you to believe. Considering that the dead-nuts simple 7.3L gas V8 gets by without the need for EGR at all (yes, I know emissions regs vary based on GVRW). Take a look at this video we shot of the underhood happenings and the accompanying pics. How far off do you think we are from seeing GPFs (gasoline particulate filters) bolted onto new vehicles here in the US? For such a small engine, the 2.7L EcoBoost certainly packs a lot of plumbing under the hood. Here's a good shot of the EGR valve, and various sensors, mounted on top of the valve cover. Looks like everything is easily accessible for 'servicing'.
