It probably would be fine to use, but I wouldn't of bought it if I knew it was a white filter and not black like it says. This model number was probably a black filter at some point in time, but as of today 21-203BF is a white filter.

En la publicación se muestra que es color negro y llega en color blanco, la calidad se ve buena pero el color desmerece el producto

These are great filters. Last one I ran for 10 years. Never even cleaned it and it still seemed to be performing well. An excellent filter for custom setups. Especially if you don’t want to use the dumb oil soaked filters. There’s a reason OEM manufacturer’s don’t use oil filters. They are poor quality. And don’t work.

AEM is a pretty good air filter in my experience. I had mine on my Mazda 6 AEM CAI for about 11 years before i had to replace it. I am currently using this specific one for my custom air intake for my Honda Pilot and it is working with no problems so far. Great product!!

Utilized these intake cones to fabricate a custom intake for my BMW M5. Top notch quality dry flow filters. Would definitely buy from this seller again! Thanks!

This is an off road filter which is not in the product description. The product box looks like it was beaten up badly.

I bought this to replace my old K&N on my Probe GT, I had heard that oil based filters can damage your MAF and after doing a lot of research on the web I found a guy that tests everything from paper filters, to K&N to dry flow, and after seeing his results, I decided to go with the AEM dryflow. While it doesn't filter as good as a factory or paper filter, it does allow more air in through my CAI and actually has better flow properties than the K&N and it was almost scary to see how little K&N's filters actually stop dirt vs. a regular filter. Basically my choices came down to the AEM Dryflow or the Injen Dry Filter and in the end I went with the AEM simply because they had similar test results in flow & filtration and the AEM (at the time) was about half the price. All-in-all I'm very happy with it almost three years later.Oh, and yes the box says "Off Road" but it isn't referring to it being for off road trucks, it simply means it's meant to be used in more track settings like an aftermarket exhaust or other "go-fast" parts so they cover themselves by saying not to use it for every day driving.
