I've got a K&N cone filter on order I was going to play around with on a mod like this, and I've got a Chrome Big Air on backorder. Today I got tired of waiting after some inspiration for some couplings I saw Sled playing with. So I bought these cheap import filters to do a mock up. When my K&N cone filters come in, I'll swap those on - they should fit right on the ends. And when Big Air comes in I'll change to that. Then I'll have three air comparisons. Here are some pix of the mod done today and a kudos to Sled. I was already on the verge of doing this, but had hesitated cause I wasn't sure the couplings would fit together. Today Sled demonstrated that they would, so I jumped on doing this mod just for some fun.
