Soon as I put these filters in my BMW X5 4.8, I noticed a complete difference. The acceleration was incredible. I will use nothing else, from now on.

I bought these filters, and they were very easy to install. The car feels smoother and throttle response has improved.I will wait a few tank fulls to pass judgement on the fuel economy but the cars feel better.
