Description

Needed a better way to fill the Porsche with oil. So I created this burp-free vented funnel that twists in to the engine just like the oil cap. It keeps it secure so it wont tip over and leak free. Also included is a reservoir base to screw the funnel in to after you are done filling the car. This will keep it upright on the bench and catch anything that drips down from the funnel. I use this on my 3.6l Macan Turbo but should work on other models too. Made it in PLA but if you plan on using it on hot engines use ASA.
