The OEMTOOLS Vortex Funnels are made in the USA and feature a vortex design that vents air to accelerate flow, delivering up to three times faster pours than standard funnels, according to the company. The internal spiral eliminates airlocks and turbulence, ensuring smooth, uninterrupted transfers of oil, coolant, and other fluids. Other innovations include a triangular body that fits securely into round fill ports for greater stability during use. Available in translucent gray and translucent green, the funnels are made from durable, chemical-resistant materials.
