Can someone tell me the air inlet diameter of the Gen 3. I am making a rodent screen but don't have the car accessible. I'm thinking maybe 3 inches?
Engine air inlet? Assuming yes, I would wait till you have the car accessible. I took that snorkel out to do it properly, cut out and formed a piece of rodent mesh (galvanized steel mesh with 1/4" spacing), with bent-up edges and corner's clipped, drilled 4 small holes through the walls of the inlet, pushed the mesh in, secured with copper wire "twist ties".
I was thinking something like that but externally attached to the very end of the air tube. Maybe circular with four extended tabs bent over the end and attached with a zip tie around the outside. Not as clean but more easily done from a distance. I just need the inlet diameter which I believe is circular. Also, this would keep rodents out of the whole system.
