Review on 🌬️ Mann Air Filter C25 114/1 by Josh Nat

Works well. Replaced my "lifetime" K&N filter, it was dirty. Suitable for all BMW E46. Make sure you press down on the filter so it's firmly in place. Installing the air filter housing was a little tricky, I had to push it down a bit, but when I put the clips back into the bottom of the housing they clicked nice and tight, good fit. This MANN filter comes with a pre-filter on the bottom , the stuff is about 1/4" thick. I think they sell the model without it too. Shouldn't matter much. Will update if I notice MPG improvements or throttle response. Oh, and PROPS for Revain on delivery! Me ordered this on Friday at 3pm and received it on Saturday at 10am, now it's FAST SHIPPING!(Revane Prime)
