January 3, 2018 - Part 8131
Well made, easy to install, good flow.

Installed this on my Honda VTX 1800R by attaching it to an aftermarket intake plenum. It fit like a glove and looks awesome. I can absolutely tell the difference between this filter and my last one. The 8131 allows a massive amount of air flow through and I could immediately tell the difference on the low end torque and the sound of my bike. Very pleased with this product.

I just got this after I already had 9131 3 inch cone filter on my car, and when these came out I wanted to give it a try. It does let more air in than the first filter, and this filter leaves other add ons open if I feel I still want more from my ride...
