Our Customers Comments
All - Update on the dual quad velocity stacks. I changed spark plugs when I installed the stacks so I could watch the color of the plugs. The stacks did in fact slightly lean out the engine, which was a good thing, (was running rich).
Air flow is much improved and fuel economy made a improvement by about 1.5 - 2.0 mpg. Cooler air as well as velocity helped in improving economy. These were all still during the hotter days that we had. We are just starting to see cooler air now as Fall approaches.
The other indication that the engine is running slightly leaner is the back wood tailgate would "soot up" due to the upswept exhaust tips and running rich. I have all but stopped having to clean the soot off and there is just a light film of it even after two weeks of cruising.
The mounting system has worked well and actually helped in installation of the stacks also.
So far, so great!
Thanks again.
