Vented Vortex Funnel set

I liked some of the screw on funnels out there but the screw cap part was attached to the funnel itself. Since I am not brand loyal, I ended up with multiple funnels.

This design gives you a vented funnel that fits 3 different, 5 quart oil jug adapters: Castrol/Mobil 1, Pennzoil/Quaker State, SuperTech.
Using the funnel without an adapter will fit the Motorcraft sized jug. I added threads to the top of the adapters so the cap can be screwed back on without removing the adapter from the jug.

2 funnel sizes are provided, smaller mouth (125mm) and a larger mouth (150mm)

Vortex design for extra power! ;p
