CVFab Mods Installed on My Bronco, But Then THIS Happened | P04F0 Check Engine

In today’s video, I’m reviewing all the CVFab Performance parts I installed on my 2-door Ford Bronco, including the cold air intake, charge pipes, intercooler, and cat-back exhaust, while also putting them to the test with real-world Dragy performance data. I’ve been daily driving and off-roading with these mods for a few weeks now, and I’m giving you my honest thoughts—what works, what doesn’t, and what you should know before buying. One important issue I highlight is a check engine light (CEL) that appeared shortly after installing the intake, specifically error code P04F0 (Evaporative Emissions System – High). I walk through how I worked with CVF to troubleshoot the issue, what we tried to resolve it, and what to expect if you experience the same. I also dive into how the charge pipes affect blow-off valve spacer compatibility, the intercooler’s tradeoff with active shutter removal, and why the exhaust might not be ideal for serious off-roaders or frequent towers like myself, despite its great looks and price. Finally, I compare Dragy hits before and after installation, factoring in Florida heat and DA variations, which slightly skewed the results. All parts shown are available at buckleupoffroad.com, and I’ve got more installs and reviews coming your way—so don’t forget to like, subscribe, and as always—Buckle Up Buttercup!
