I recently upgraded my vehicle's air filter to the K&N Engine Air Filter, and I'm absolutely thrilled with the results. This product has proven to be a game-changer, offering a level of quality, fit, and performance that not only matches OEM standards but surpasses them. The build quality of the K&N filter is exceptional, and it fits my vehicle perfectly. Installation was a breeze, with the filter sliding seamlessly into place. The sturdy construction gives me confidence in its durability, ensuring long-lasting performance. However, where the K&N filter truly shines is in its performance. The increased airflow has made a noticeable difference in my car's throttle response, providing a significant boost in horsepower. The engine runs smoother and more efficiently, delivering an enhanced driving experience. I've also observed potential improvements in fuel efficiency, which is a fantastic bonus. Maintenance is a breeze with the K&N filter, as it is washable and reusable. This not only saves money in the long run but also contributes to a more eco-friendly approach to vehicle maintenance. Considering the unbeatable quality, perfect fit, and outstanding performance, the K&N Engine Air Filter is a must-have upgrade for any car enthusiast. If you're looking to elevate your vehicle's performance, I highly recommend making the switch to K&N. It's an investment that pays off in increased power, efficiency, and long-term savings. Don't hesitate – upgrade your air filter today!

K&N is a good product already so those who have used them know that they increase airflow to your engine. Although the price may be high, they are able to be cleaned and oiled and reused for life.

Would I recommend a K&N air filter? Short story is yes - this is a 5-star review. I like that it is a permanent filter you can clean and oil over the life of the vehicle. I like to think that it improves air flow and perhaps a negligible HP increase. I have always put K&N in my vehicles and plan to continue doing so. That being said, I've always wondered whether the stated MPG increase is real or perceived. From a pretty data-driven standpoint, I now have reason to question the claim of better mileage with a K&N filter. I purchased a 2018 4Runner brand new and started logging every single fill-up from 6 months post-purchase. After 14 months of logging fill-ups, I replaced with a K&N filter and continued to log all fill-ups. I don't drive as much as some (26K miles on a 4 year old vehicle), but the driving has been fairly consistent. Overall I have 78 fill-ups logged with 50 pre-K&N, and 28 post-K&N. See the attached photo for the outcome of this experiment. I looked at strictly the average of all MPG data points pre-K&N, and post-K&N, finding a nearly 5% LOWER MPG after installing the K&N. Knowing that my driving may have shifted and I had a few really high ones (strict highway driving) and a few really low ones (towing a trailer) on both data sets, I removed any data points more than 1 standard deviation from the mean on either side. The second column still shows a nearly 3% decline in MPG post-K&N install. I plan to continue logging my fill-ups and will see how things change over time. I do believe that with a larger data set, the numbers would get closer together, but I don't believe you will see significant increases in MPG after installing a K&N air filter. It won't pay for itself in the gas savings, but could pay for itself in the long-term due to no disposable filter replacements

No surprises means great.

Perfect fit in a 2018 4Runner SR5. Easy drop in installation. I was able to get an additional 1.4mpg after installation. I've run about 1,000 miles on it since I installed and have been on one road trip with it. I personally really like how its reacted with my vehicle. The car seems a bit more responsive when driving around and you can definitely hear/feel the difference when rapid acceleration between 40mph - 60mph. My car now has a nice growl to it when driving at higher speeds. My only disclaimer I'd add in about dropping in the air filter at least in my case, it added a whistling type of noise at all driving speeds, similar to that of a diesel engine or larger trucks which Is pretty faint and eventually you get used to it & well it doesn't bother me much since now it sounds like I'm driving a real truck.

I have been using the K&N filters in my wife's Ford Flex Ecoboost for several years now and though I would give it a try in my Lexus GX460. I remember it being a notable improvement in the Ecoboost, but it is a world of difference in the GX460. The engine really comes to life, and is more responsive. Without a doubt worth it in a GX460. Always felt the engine was sluggish and lumbering. The filter in the GX460 is physically huge, so it makes sense that getting the additional airflow from the K&N really makes a difference.

It seems like a good design, but I've ordered a couple of these and the fit and finish was very poor. I will try again one of these days to get a good one

Works great fit good
