What is "Difflow"?

Who We Are

Established in January of 2010, Difflow started designing and manufacturing rear diffusers for Lotus. The demand for our unmatched quality, durability, functionality, and style has grown and we are now the leading manufacturer and retailer of non-carbon Diffusers. We are an online-based company, with Authorized Dealers selling our products all across the United States. We ship Diffusers to customers all around the world!

We Love Our Customers!

We have traveled all over the country testing out our diffusers. During that time, we have hosted customer appreciation events, car shows and luncheons. We have met a lot of great people and we truly appreciate all of the customers that have supported Difflow.

What is the purpose of our products?

Difflow Diffusers remove the restrictions of your car's aerodynamic performance by reducing your coefficient of drag and reducing lift, effectively increasing your vehicle's overall traction and stability.

Difflow Diffusers aren't just about looks. We have seen our diffusers improve drivers' lap times and even make them more comfortable driving their own vehicles! Don't just take it from us, see what some of our customers have to say about their diffusers here!
