K&N 33-2381 Air Filter Product Reviews

I have been a K&N customer since 2000 and bought K&N air filters for all my new vehicles.

I have been using your products on my street cars and my racing vehicles for the past 20 + years.

I replaced my dual factory air filters with two matching K&N air filters, in my 2016 Lexus LS460. Perfect fit, and while the old air filters were not dirty, I noticed an immediate improvement in my fuel economy from the dash mileage indicator, about one additional mile per gallon (approximately 5 gain around town). Now I have an after market chip installed which had already improved my mileage to begin with (about 20 around town), so no idea how it will work for someone else, but I should imagine it would do well. Cannot tell about improvement in the power output which is already pretty high, but more air means more power, so I think there must be an improvement.
