Stock blow-off valves like those that come standard with the Explorer often suffer from a range of problems. The plastic construction can lead to cracking and leaking, and if you want to up the power (who doesn't?) they can have trouble holding the extra boost.
Turbosmart’s Kompact dual port blow-off valve system provides a remedy to all these issues. The all aircraft grade aluminum alloy construction means cracking and leaking even under increased boost levels will never be an issue, while new Turbosmart technologies provide a serious increase in performance over stock valves.
Note: Only one blow off valve needs to be purchased on 2020-2021 Ford Ecoboost Explorer ST models.
