"I've used K & N in my previous vehicles with great results. My most recent installation has mixed results. Every few days I am getting a CEL for a system lean code. I am putting a new stock filter in today to see if the problem goes away. The install is lengthy compared to other vehicles but that is due to Audi." —Richard B from Stamford, CT bought a K&N Air Filters for a 2002 BMW 3-Series.
"I was staying at a B&B in Key West. And was told about this outstanding filter. Better than original was the claim. I kind of doubted the claim. But it was time to change the filter on my BMW. So I figured why not give it a try. To my doubting mind I was amazed at the immediate increase in car power. I asked my wife to drive the car. Same overall comment from her also. Have not had the filter on the car long enough to say if it also increases my gas milage but from initial observation it has not hurt it." —Ron L from Lindenhurst, NY bought a Green Air Filters for a 2002 BMW 3-Series.
