K&N High-Flow Original Lifetime Engine Air Filter: Washable, 33-2452

'14 Lexus Gs350 FsI 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 *

Brought my gas mileage up a good bit, easy to install. Only had it for a week but works great!

Great replacement for the oem filter. Didn’t expect much from a filter but I instantly felt a difference. Felt like my motor could breathe better and small power increase.

My boyfriend swears by these filters and uses them on his Nissan 370Z and our Trailblazer. He suggested that I get one for my 2015 Lexus IS 250. I did and thought I would have the dealership install it during my next oil change, which he thought was cute. He popped out my old one and stuck in this new one - took him about 10 seconds.My car has only 10k miles so the OEM filter was still pretty clean, but I noticed the original was twice the thickness of the K&M brand filter. Apparently the slimmer design helps the car to "breathe" better, which to me just sounded like a sales pitch or advertising tactic; I was just happy with the fact that this filter could be cleaned and used for years without needing a replacement.However, I was pleasantly surprised at the little extra pick up that I felt when driving my F Sport IS, even without having the power function on. It honestly felt much more peppy and sprightly to drive. The change in horsepower was noticeable; not game changing, but noticeable, and my engine became ever-so-slightly louder, but in a good way. It instead has a slight roaring sound and lost the usual Lexus "ticking" sound when idle, which I was astonished to learn/hear. And for less than $60, the price of this filter and the improvements it offers is worth its weight in gold, IMO. I am a believer now, too, and highly recommend this filter.

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.

Slim filter, it's probably about half the height of the OEM filter, letting more air in. The materials feel solid, and it's reusable. No gaps around the sides. I don't feel any difference in power, but you can hear more air being sucked in, especially since I don't have mufflers. No noticable difference in fuel economy. Came with a K&N nice sticker.

I have an increase in acceleration and it seems to sound a little better but I feel I definitely lost about 2 to 3 miles per gallon on a long drive. I was getting 27 to 30 on a long drive and now I’m roughly averaging 25.

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.

installation difficile sur rav 4 ,pas au mesures exactes 2014 ,aucune amelioration ,beaucoup de bruit d aspiration,du coup,retour à filtre normal,un achat pour rien

Very good product and excellent service.

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 GasannahmeDer Motor wirkt lebendiger und zieht gleichmäßiger durch. Besonders beim Beschleunigen merkt man den Unterschied.✔️ Hochwertige VerarbeitungDer Filter ist robust, sauber verarbeitet und macht einen extrem langlebigen Eindruck. Kein Vergleich zu Standard‑Papierfiltern.✔️ Wiederverwendbar & waschbarEin riesiger Vorteil: Man muss ihn nicht ständig ersetzen. Einfach reinigen, ölen und weiterfahren. Das spart auf Dauer richtig Geld.✔️ Passgenau für viele ModelleIch 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 LeistungszuwachsNatürlich ersetzt er kein Tuning, aber der Motor läuft spürbar effizienter. Auch der Klang wirkt etwas voller.FazitDer 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.
