You've seen the dyno charts showing how much more power the BMS open air filters make. You've watched the videos showing how much better they sound. You've read the hundreds of favorable customer reviews. And after all that you still prefer a high flow drop in filter?

Worry not, BMS has got you covered! Introducing the BMS drop in filter, offering quick installation and the best flow of any available drop in filter. It's manufactured by S&B to the same exacting standards as
our high performance dual cone filters.

We can't promise the same power gains or sound you'll get from our open element intakes, but we can promise this will significantly outflow your paper filter and is extremely easy to install and remove. Plus it can be cleaned and reused for up to 1,000,000 miles. And since the N54 does not utilize a MAF sensor there is no need to worry about filter oil damaging sensitive electronics!
