K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2012-2020 BMW: (See Product Description for Select Models), 33-2990

Been using this since my first car, almost 30 years ago. Never failed me. You can feel the lighter acceleration once you drop this in the filter box. Then you can forget it like you ever need air filter again.

Nice filter. Slight increase in performance but its nice to not have to throw out the old filter every 500 miles.

I have installed K&N filters in all are vehicles and not sure if they is big change over a new oem filter in a stock box, but there longer lasting and easy to clean. I believe it filters air better and intake path stays clean, even in extreme conditions and cost savings over time make it a good value.

Ok

This filter is very well built, and depending on which model vehicle you have, will easily pay for itself after two regular air intake filter changes. This was recommended to me by a mechanic who works on jet engines and can fix just about anything. It does was it claims to do. Whilst I don't notice any particular level of performance improvement, I am happy knowing that my engine intake is protected and also that I won't have to spend half the price of this every year for a throw away piece of cardboard filter.NOTE: I've read other reviews complaining that the filter was "wet". This is by design, it is an oiled filter and that enhances the particle collection whilst protecting the filter. There are cleaning kits available that include oil that should be reapplied after cleaning at the 50,000 mile interval. I wish people would actually read the instructions and understand what they are buying before posting a review. Especially with a filter with a higher entry price.

I have put off buying this product for years…It works as advertised!You can feel the difference.It will pay for itself in 4 oil changes.

Power is more linear now in my manual.Engine would bog down pass 4k rpm at 1st gear.Now I can shift closer to 6k with minimal drop in power.Installed afe air scoop also and ride is much much better.

Works as it should
