What Our Customers Say

“Just to let you all know I have the Crawford Fuel Saver Q2, in two days my mpg has gone up by 3.7mpg and my car is driving more smoothly with a much better acceleration. This is by far one of my favorite mods, and it takes less than 5 minutes to install.”

— Isaiah Terry, 2011 Scion tC

“I was getting 340 miles per tank, now 370 driving even harder. Seems to have more up top. At this point I’m totally sold on these.”

— Facebook User, 2006 Toyota Tundra

“I used to get roughly 13 to 14 mpg and now roughly 16.5 mpg lovin it, any kind of increase is good for me! Thank you! This will definitely pay for itself many times over!”

— Facebook User, 2012 Toyota Tacoma

“I received my two Q2 fuel savers from you. I installed the first one in my 2014 Rav4 AWD. It added a feelable power to the car and gave me an average of 3 mpg better fuel mileage, the best now is I put the other on my FR-S. WOW!!! I never thought it would make such a great performance difference! It now wants to squeak the tires on every takeoff, and for the first time it actually pulls me back in the seats on shifts! WOW! Best $50 I could ever spend on a part. I am very happy!”
