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

K&N quality you pay for.

Works great fit good

Highly recommend! I've seen two major enhancements to driving my 2020 4Runner.1. There's just enough Horsepower boost to avoid flipping into and out of S42. After a few thousand miles my average MPG went from 16.6 to 17.9

I've put K&N filters on all my vehicles I've owed, never had a problem with any of them, it's great way to save lil $ and get lil more power.

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

I might have traded 1 MPG in for a bit more throttle response and frankly, I'm OK with that.The 4Runner is a dog (especially if you just transitioned from a sports car), and I was moderately frustrated driving this SUV in dense traffic because of that. This air filter didn't stop it from being a dog, but it's tolerable now to get up to speed without feeling the inherent asthmatic nature of this heavy, naturally aspirated 6 cylinder SUV. I hope this helps you understand one of the real benefits of this filter for 5th gen Toyota 4Runner. Thank you.
