I was wondering who makes the filter for Steeda's SRI. I heard rumors that it is made by S&B but I can't be sure. I know it is dyed with blue oil and S&B is the only company I can find that sell that stuff. The reason is I want to know how well the filter actually does its job in comparison to other filters such as K&N or AEM. I emailed both Steeda and S&B. No help from S&B and Steeda has yet to get back to me. Any help would be great.
