I recently went to the store and was about to buy a new AEM Dryflow filter. I saw there was one that was white, and one that was gray. I'm guessing the white one is newer since the box for the gray one was kind of messed up. Both has the same product number, same box design and everything. Are there any difference to the white or gray filter?

 

probably just color change, the filters themselves are probably the same.

 

White shows dirt.

 

They actually are two different filter medias, but I'm not sure how much longer you'll be able to get AEM filters as K&N just purchased the filter side of AEM this past week.

 

What are the differences? Which would you recommend?

Wouldn't the two filter at least have a slightly different product number? I mean, the packaging and everything was the same for the two filters.

 

I'm sure you as a consumer will notice incredibly little difference. And in all honesty I wouldn't have even posted about it. More than likely it was just cost of materials or what not.
