    Great product very reliable, never have to worry about buying a new filter now this will last a long time. All I have to do is clean it from time to time when it gets dirty. Very helpful on hot days getting more oxygen into the car. You’ll notice a slight change in acceleration but not a huge amount it’s a engine air filter not a supercharger. I’ve used K&N products before in the past on other cars it’s great for reliability and saving you money in the long run.

    I’ve been using K&N air filters for many years on multiple cars. They are easy to clean and end up saving you money. Its nice to know you can have a clean air filter anytime you want one just by cleaning yours. In all the years and through the many vehicles I’ve never had a K&N filter become damaged. I clean mine 3 to 4 times a year, I know, it’s over kill, and I’ve never had one wear out or get damaged. They are built to last and they do.

    As a long time user of K&N products, I know the benefits of their added performance and longevity over OEM applications. And although a 2017 Lexus RX 350 F Sport is NOT a “high performance” vehicle, it’s driving performance has been noticeably enhanced by simply changing out the restrictive paper element for a K&N Air Filter. The difference is night and day for the better! I HIGHLY recommend this simple change, you won’t be disappointed!!

    I love the air filter I noticed more mpg in my drives and a better acceleration response. I’ve used K&N engine filters in my last car and now in my new current vehicle I’m always satisfied. People have to understand these filters help the engine breathe better they are not turbos so don’t get made if your slow car is still slow can’t blame an engine air filter.

    This is an incredible air filter, which I easily installed in my 2010 Lexus RX350. I have noticed a big difference in the performance; starts from red lights have greatly improved with this filter. I also did a 0-60 test and reached 60 mph in 6 seconds — impressive for a 10 year-old SUV. I plan to purchase and install a similar filter for my 2004 Lexus 330.

    This air filter really is fantastic. I noticed an increase immediately in my avg mpg. I added 2-3 more miles immediately to each gallon. Does not sound like much… but in the long term that is HUGE! That is a “free” gallon of guess every fill up. Incredible. And I think there is a little bit more of an engine “growel” than before which is nice too

    I have recently purchased the 33-2443 K&N Replacement Air Filter for my 2019 Toyota Camry XSE 3.5L. Installation was easy. I have noticed better throttle response and a slight increase in horsepower and gas mileage. I would highly recommend this product for this type of vehicle and engine.

    Replacing the overly restrictive stock air filter with a new K&N Performance Air Filter is such a simple upgrade and results in immediate improvement in acceleration. The added bonus in the 2-3 MPG improvement that is very much appreciated given the insane price of gasoline today,
