Great upgrade from a paper filter
Good quality. Definitely makes my Lexus GS350 F-sport sound / perform better. Gas mileage is a little better.

Saves money in the long run
Good fitment, and I will save money over the life of the vehicle. Others mentioned an increase in sound, we have not noticed any and the car still drives well. No noticeable increase in acceleration, or gas mileage.

Get the correct size and you can DIY in 3 minutes
My 5th one for my 5th car in 6 years and it definitely helps the engine breath better and adds 10 hp on average. Great air filter

Makes my 2020 Lexus GS350 Fsport sound even more aggressive when full throttle
Made my 2020 Lexus GS350 Fsport AWD sound even more aggressive when full throttle from the intake, when driving conservative I can get 29-30mi per gallon on highway which is a couple miles higher than EPA rating. Not sure if it increases horsepowers but The car feels more responsive or this may be just a psychological lol. It also fits perfectly into the filter box so no modifications is required. Also important thing to mention that it will not woid any manufacturer warranty and this is another reason for me to buy this filter, because my car is Lexus certified and still under warranty. This is my third k&n filter I also buy them for my Mazdas.

Gave more air
This was an easy install, just replace the old one. The engine sounds better and feels like it is able to breathe more. K&N is great. I've used them in all of my cars and trucks. No issues whatsoever. I don't know if I'll ever get to experience their million mile warranty, but I've gotten over 300 thousand so far and it's been good. Don't forget to clean them once in a while.

Good Filter
I've heard a bunch of mixed things about the filtering potential of k&n but I've never had an issue with them before so on it goes! The puralator filter i had on before had the paper filter and the additional cotton filter on top of that. The intake itself has a small mesh/fabric filter on top too, so I feel like unless I'm off roading or taking a gravel driveway every day it shouldn't matter that much. Performance gain? Maybe. Fuel economy? No idea. Maybe a little. Intake noise? Definately more than that of the puralator. If you like the idea that the cars such as the gs 350 will be dead silent until they wake up at about 3-4 thousand rpms, then don't get this filter. You like hearing her purr like a kitten? Might be the filter for you. I like the idea that these are re usable, just skeptical on how to oil without throwing a maf sensor code, but we will cross that bridge when we come to it in 50k miles(rated for "75k", I'll probably clean it every 50 just to be safe). Overall though, packaging is nice, presentation is nice, and it fit pretty well for being "aftermarket."

Encaja a la perfección para sustituir el filtro de aire de serie. No se nota diferencia de comportamiento, tan solo varía levemente el sonido. Como ventaja tienes filtro para toda la vida del vehículo.
