🚗 aFe Power Magnum FORCE 54-11478 BMW 3-Series (E9x) Intake Systems Scoops in Sleek Black Finish Review

Quick and easy installation. I had to trim a bit to get everything to fit properly and I recommend buying nuts and bolts for a secure fit. In terms of performance, I felt the difference while driving. There is less lag.

Not sure if that makes a huge difference in performance, but it probably gets a little colder under the hood, not a bad setup, but I had to tweak and bend the metal a bit to make it fits in my 07 335i sedan, also with bms dci.

High quality and reliable product. I would recommend checking the aFe website directly to confirm the fit of the model as the Revain fit guide said it would not fit my 3 Series model. The increased power is almost imperceptible, but I would expect it to help with air intake in hot and muggy summer temperatures.

Great addition to my 06 330i. Simple packaging and very easy installation, took about 15-20 minutes. In terms of performance, there's a significant power increase and an increase in MPG (along with a cold air intake), but not at the same time. If you cut the throttle you won't see an increase in mpg. In 4 hours of driving at an average speed of 70 mph I saw an increase of 27 mpg when I was about 22 mpg before.

Together with the mod to remove the activated carbon filter airbox, they really make a difference. Better throttle response at idle and more power at 40 mph plus. It's not louder, which is what I prefer on a daily basis, but they work as advertised. The instructions say it's easier with two people, but it wasn't hard at all to do by myself in my garage in under an hour. I'm glad I spent the time and money on the mod. Update - my MPG has increased slightly by around 1-1.5 MPG.

Not sure if it is because the models are different but the installation on my 328i was very easy. The only complaint is how expensive they are for small sheet metal parts. I think they should be more cost effective for what they are. The delivery was crazy by the way. I ordered them at night and received them the next morning. I can't talk about wins or no wins yet, but knowing what I know they will obviously help.
