aFe Power #31-10208 Magnum FLOW OE Replacement Air Filter

fitment in my TRD CAI was perfect! install was easy and quality is nicer than the other options ive seen.

Installed on my new 2019 4Runner TRDOR, easy install thanks to Toyota making the factory airbox painless to get into with no tools. Filter is of high quality and seals well. Only about 150 miles with the AFE filter but compared to the original factory paper filter throttle response was immediately and noticeably improved, too soon to say for any mpg improvements but would estimate I’ll see a modest 1-1.5 mpg improvement over the long term. Induction noise is slightly increased, around 2000 rpm and up can hear air whistling past the throttle plate, doesn’t bother me at all but is worth noting. I’m located in Arizona where it’s super dusty, as good as the AFE filter is I’m keeping the stock paper filter under the front passenger seat to swap back in before heading offroad for added dust protection. Overall have had AFE dry flow panel filters on three different vehicles and each of them benefited in throttle response and improved mpg, I recommend them.

Very good filter. Gained 2 mpg also

Perfect!! Fits my 2016 4Runner with no issues. Throttle seems more responsive than the stock element. My exhaust (aftermarket) seems louder as well. No gas mileage increase or decrease noticed. I've had these filters in the past, so I already knew what to expect. Very easy maintenance and install.

Same great product, as usual. Installed on our 2017 Toyota 4Runner. I've been running these on my vehicles for about the last 5 years. Don't expect much noise difference, at least on the Toyota v6 it pretty much sounds the same. Acceleration may have a slight gain but honestly it might just be wishful thinking. Clean the filter out before you install, they always have loose flakes of rubber in them.

I really like the quality of afe, however it works fine till 200k km, but for the price it is good

I use aFe Pro Dry air filters in ALL my vehicles. They work really good and are easy to clean. I can't say if it increases HP but in all my vehicles (4) it "smooths" out the way the engine runs; it quiets them a little and they seem to run a little better. This is a direct fit in my 2015 Toyota 4Runner.

Seems to help my 2015 4Runner breath a little easier. No noticeable mpg increase (if any). But the truck does seem to accelerate a little faster, lower in the rev range. Power seems to come on around 2000 RPM, as opposed to 2500 with the OEM filter. It's also nice that I never have to buy a new filter again for the life of the truck.

More than I expected. Not a lot of hp, but a lot more pick up.

Installed this in my '14 FJ, which I regularly drive in the desert. Airflow is noticeably improved on and off road, and super easy to clean.

Worth the money any engine

Works as described.. HP am not sure but car breaths better .. I prefer this over oiled ones. Much easier to manage ..
