Performance, Savings, & Durability
I have run K&N serviceable filters in our cars/trucks for over 20 years now; a total of six different cars & trucks. These products provide overall savings, are very durable, and MOST importantly offer great filtration for your engine air intake all while allowing a greatly increased air flow. Purchasing this latest filter for our new BMW 530i xDrive. Of course these filters cost a bunch more than disposables. The last one of these I bought was for our 2015 RAM 1500 truck. So for over nine years now we have saved approximately $330, that is the K&N serviceable filter compared to disposable semi-annual replacement over the last 9 years. Cleaning/servicing is easy and the K&N kits ate about $16-17 currently - you can get at least 10 cleanings out of a service kit.Performance is great! Invest in a filter for your vehicle, promise you wont be disappointed!

KN quality
Perfect fit, best value filters as always. My car even sounds little bit more car-y. Can’t speak to performance or responsiveness, but KN is always solid.

Great fit
This does exactly what it is supposed to do. It fits really well and is built to the standard I’ve come to expect from K&N. I like that I can clean and re-oil the filter as often as I want instead of having to replace it. Don’t notice a difference from the stock filter.

Drops right in to my 19 g30. I can hear blow off valve noises now and my car feels a little faster and get the induction noise. Haven’t really tested the fuel economy since I’ve been busy better listening to my car. I’d recommend it!
