nice and fast shipping

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

My wife bought an NX300 and I a GX460 in the same month. Hers has a turbo and needs all the air it can get, so I installed a K&N the day after we picked it up. But I did a lease with the GX, and ended up buying it because I only put 9000 miles on it in 3 years due to Covid. So I never put a K&N in it. The whole time not loving the vehicle at all. It was a gas guzzling pig that couldn't get out of its own way.So my wife had some sputtering and stalling problems with her car 2 weeks ago. I quickly figured out that it only happened above 3000 rpm. So I met her in the CVS parking lot where she didn't want to drive it home, gave her my daughter's car to drive home, and I drove hers home. Sure enough, cylinder 1 code, and really burned up plugs. So I swapped the plugs early at 73k instead of 80, and cleaned/re-oiled the K&N that was already in the car. Then I swapped in some new coil packs. 120k mile lifespan my foot. I also threw some injector cleaner in the tank for giggles. Runs like a beast again. But although the filter didn't look dirty, it was. My wife said she could now hear a low "wind noise". So I said "stop jumping on the gas then" lol. She said "how did you know?" I said "That's the noise a car makes when it needs to breathe, and as of today, it CAN again. It's amazing how much better these K&Ns work when they're clean.Anyway, I went on an errand a few mornings ago in the GX, and man oh man what a pig. So I turned off the stereo and opened the windows. "Ah hah, I can't hear any intake noise AT ALL." So I went on Amazon and ordered this one. It came today, and I popped it in. WOW!! I've had these in everything from Hondas to Mustangs. NEVER have I felt such a difference in acceleration. The pig grew wings! We'll see how the gas mileage goes, but now that I can stomp the accelerator to have it take off almost INSTANTLY, and throw me back in the seat, I don't care, lol. So if your goal is gas mileage, I can't vouch for that yet. But if your goal is performance, shut up and give Bezos your money, lol. .....now let's go read up on those throttle body spacers.....

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

Great product, easy to clean especially if you can put in a paper filter for a day or two while you let this one dry. Mine got too dirty and damaged due to heavy driving. I sent pictures over to K&N and they are sending a replacement.

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
