  • Why Removing Charcoal Air Filters Is Generally A Bad Idea Visit to download the free RetailMeNot Genie browser extension (this video’s sponsor) today and start saving the easy way. Will removing a charcoal air filter increase horsepower? Charcoal filters are designed to capture hydrocarbons that may escape out your intake when your car is shut off. They’re located after the air filter in your intake duct, and can restrict airflow. But how much effect do they really have on performance? I took two air filters, an OE filter and a performance filter, to the test, with and without the charcoal air filter. To measure the differences in horsepower and torque, each of the four filter options was put on a Mustang dynamometer, with multiple runs. A VBOX was used to measure real world acceleration differences. How much of a difference does a charcoal filter make? Check out the video to find out!

    Charcoal air filters do indeed rob your engine of horsepower. Or do they?

    Never heard of a charcoal filter being used in the air intake. Yes in the CABIN

    I took my manifold and throttle body off. The power gains of absolutely no restriction is amazing!!!

    "Do not tamper with emissions equipment." Challenge accepted. EGR removed, down pipe installed, ECU mapped for performance.

    Wonder how restricted the coal filter is after 200k since it is never replaced... Yes it is after the regular filter but still, nothing's perfect,

    Jason, how about testing these options on long trips to see how much/ if any fuel mileage benefits?
