Heat soak is a major obstacle when extracting higher power figures from the 2.3 EcoBoost engine on the Focus ST Mk4. Upgrading your thermal management hardware is incredibly important if you are planning power increases via software recalibration, with uprated Intercoolers being one of the most vital modifications to drastically lower intake air temperatures. Keep charge air flowing smoothly with heavy-duty Boost pipes, maintain stable engine oil temperatures under extreme track loads with dedicated Oil Coolers. Upgraded Header Tanks can prevent age-related wear and failure, whereas Oil Catch Cans help to prevent oil build up allowing your 2.3 EcoBoost to run sweet!
