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

💯 Worth Spending The Extra Money If U Are Passionate About Your Ride
'14 Lexus Gs350 Fs I considered buying this filter for well over a year. But i didnt think there could be that much of a diff between a $30 OEM & this K&N filter. Well...there is a diff, a big difference! This filter was one of the easiest & one of the most satisfying upgrades ive done to my car. Immediately after installation, i noticed more horsepower. That sounds crazy, but it is the truth! If u are now wondering, well did it make the engine sound more aggressive, more 'throaty' - on my car, no. Maybe a tiny bit of a more aggressive sound, but barely worth mentioning. Below ive listed some of the other upgrades ive done to this car just to help gauge my credibility. *switched out OE brakes, rotors, pads for Powerstop Z26 brake & rotor kit. I did end up upgrading the brake pads from what came in the kit * switched the OE spark plugs w some new NGK ones. The coil packs i cant remember the brand but they were performance parts * swotched out aftermarket lexus rims for a set of Avant Garde M16 rims *

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.

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."

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.

Ich habe den K&N 33‑2452 Luftfilter für meinen Lexus eingebaut und bin absolut begeistert. Schon nach den ersten Kilometern merkt man, dass der Motor freier atmet und spontaner reagiert. Genau das, was man sich von einem hochwertigen Performance‑Filter erhofft. Was mich überzeugt hat: ✔️ Spürbar bessere Gasannahme Der Motor wirkt lebendiger und zieht gleichmäßiger durch. Besonders beim Beschleunigen merkt man den Unterschied. ✔️ Hochwertige Verarbeitung Der Filter ist robust, sauber verarbeitet und macht einen extrem langlebigen Eindruck. Kein Vergleich zu Standard‑Papierfiltern. ✔️ Wiederverwendbar & waschbar Ein riesiger Vorteil: Man muss ihn nicht ständig ersetzen. Einfach reinigen, ölen und weiterfahren. Das spart auf Dauer richtig Geld. ✔️ Passgenau für viele Modelle Ich nutze ihn im Lexus IS, aber er passt u. a. auch für GS, RC, Toyota Mark X, Alphard und Vellfire. Einsetzen, Deckel zu – fertig. ✔️ Leichter Leistungszuwachs Natürlich ersetzt er kein Tuning, aber der Motor läuft spürbar effizienter. Auch der Klang wirkt etwas voller. Fazit Der K&N 33‑2452 ist ein Premium‑Luftfilter, der hält, was er verspricht: bessere Performance, lange Haltbarkeit und ein spürbar angenehmeres Fahrgefühl. Für mich eine der sinnvollsten Upgrades im Bereich Wartung und Effizienz.
