Clean cap for FM oil funnel

Our thread-in oil funnel ensures you make as little mess as possible when filling your engine. But of course, you want your fresh new oil to be as clean as possible. An oily funnel that sits around on your workbench between changes is a magnet for dirt, dirt that you don't want going into your engine with your fresh new oil. 

Our clean cap snaps over the top of your FM funnel and seals it when not in use. The bottom is already closed off with the screw cap that comes with the funnel. This keeps your funnel clear of dust and your oil pristine.

Fits our NA/NB and NC/ND thread-in funnels. Won't work with our much smaller funnel adapters. Designed and manufactured by Flyin' Miata out of solvent-proof carbon-reinforced PETG on our in-house printers.
