Hordpower Airbox for Yamaha CP2

10/11/26. Hey everybody, it’s J.D. the owner of Hordpower.  Thanks so much for your interest!  I know a lot of people are wanting to get their hands on an airbox.  I have parts in hand now to build some.  Unfortunately this also coincides with harvest season.  Farming is my main gig and right now it’s insanely busy.  I will get some built and into inventory as I can.  I do not maintain a waitlist, and my store does not support restock notifications.  And I don’t take back orders because they would pile up so high that I could never fill them.  (and I don’t want $ to exchange hands until it’s ready to go out the door) It is what it is… I can’t produce enough airboxes to make everybody happy.   Your patience is appreciated!!

Hordpower airbox for Yamaha FZ/MT/R7/XSR 700 motorcycles.  This replacement for the OEM airbox will increase peak horsepower by 4-5hp by itself.  At redline, the gains are actually more like 15hp.  With a good exhaust and proper ECU reflashing, you will see peak gains around 9-10hp over a stock bike. 

-  CNC machined parts made in Reno, NV

-  Baseplate has integrated velocity stacks 

-  Hard black anodized by an aerospace company

-  Reusable K&N filter element, just clean and re-oil

-  Provision to connect the engine breather

ECU reflashing is required, we have flashes available for some CP2 models, please inquire.  This airbox fits FZ/MT models up to 2024, as well as the XSR700's.  If you are installing it on a R7, a slight mod to the fuel tank bracket is required.  For 2025+ MT-07's, you will have to fabricate your own support bracket.
