Customer Feedback

I installed this filter in my 2008 BMW 528i in under 2 minutes from hood-up to hood-down. After starting the car in the garage I didn't notice any real difference in the sound but once I started driving it I could hear and feel the difference, especially in sport mode. And as an added benefit, it looks like my fuel economy has improved by about 1 mpg. According to the car's computer, in the 1,200 miles since I put it on, my average economy has gone from 25.2 to 26.2 mpg. Very happy.

After decoding BMW, I got this fitted, makes such a difference get a nice little sound after acceleration which is great. I highly recommend this filter, the buying process was easy and delivery was quick and free.

Every BMW should have this on it from the factory. So much more aggressive sounding and improved throttle response.
