Want a little more pep from your BMW's engine and hate buying disposable filters? This K&N 33-3079 high-flow air filter is the answer. It's a washable, reusable performance filter designed to drop right into your factory airbox - installation takes maybe 10 minutes. The special cotton gauze design can increase airflow by up to 50% compared to a clogged paper filter, which can mean a bit more horsepower and better throttle response. But the best part is you never have to buy another one. Just clean and re-oil it every 50,000 miles or so (depending on driving conditions), and it's good as new. It also filters really well, trapping dirt while letting more air through. It's engineered to work perfectly with your car's electronics and sensors. Fits a ton of BMW models from about 2015 to 2020, including various 5, 6, 7 Series, X3, X4, X5, and X7 models (check the full list to be sure). Backed by K&N's famous 10-Year/Million Mile warranty. Saves you money in the long run and lets your engine breathe easier.
