Review on High Performance, Washable K&N Engine Air Filter: Replacement Filter for 2010-2019 Lexus/Toyota (GS 300, GS 350, IS 300, IS 350, RC 300, RC 350, Vellfire, Alphard, Mark X) - Model 33-2452 by Michael Jameson

Easy installation, less than 5 minutes including watching a short YouTube video on how to install. Only a flathead screwdriver is required to remove the anchor bolts in the engine compartment and access the filter box. Bought them for every car I've owned for two decades now. This latest filter came in my 2013 Lexus GS350; Immediately noticed more throttle response and acceleration with less effort and lower revs. Definitely works as expected. Updated with more information on the fuel economy improvement since I just installed it yesterday, but from the first observation it seems I'm already seeing an increase.
