I decided to design my own air filter setup after not getting any satisfaction from one of our vendors on this site. After 14 days of non communication from this company,I cancelled my order and took it upon myself to make my own. I've tried researching the forums and didn't find anything on this. Has anyone done one for themselves? I didn't think it was that hard, the most expensive part of the project was having the aluminum base cut and bored. Around $95 for that, the rest was from alot of stuff I already had around the garage. I did have to go to Home Depot and get the stainless bolts for mounting it. I also didn't like the chessy foam filter the other company used for the air intake from the airbox, so I used the stock hose and fitted a breather filter for better air filtration. After getting done and taking it out for a test run, I was more than pleased with my hard work. All together, I think something like this would cost between $130-$140 if you had to go buy everything, maybe a little more if you use a breather like I did. After finishing, I do see a few things I could have done differently but all in all I'm quite pleased with the way It came out.
