Yeah, I think that's why it was so popular on the forums five-six years ago. I mean, every other thread was how to install the 14x3. I still have my stocker with the KN which was an improvement over stock paper but I didn't like the lower filtration when I lived in a desert. So much sand and dust. Back to TBs, the Fastman comes with S bolt for the 14x3 which was always a plus. I made my own.
