Extremely duriable, flexable abs frame, cnc cut, with super strong pvc coated mesh, solvent welded to the frame with a second prefilter layer to keep fine snow and water out. We do not recommend using this vent with your stock 2 stroke air intake, dyno testing has shown a loss in peak power adding a center vent in the airsteam. We offer this vent as a replacement vent for those replacing the frog skins vent found on the BDX hood, or for those that have a modded intake, turbo ect. Choose from prefilter layer on the inside or outside of vent, out side does not plug up with snow but is susceptible to tearing from limbs ect. we do not offer our life time warranty on vents with the prefilter on the outside layer. Vent in pictures does not have the prefilter layer installed, but if ordering this vent the prefliter layer is installed. Complete with black rivets and backers for installation.
