I got them both from my local 4x4 store at the same time. A lot of online stores have it as a bundle package for a couple bucks cheaper than if you buy them separately.

Just a quick update after several weeks I'm still at a 2-2 1/2 mpg gain. I was running at 13.5 mpg and now it goes back and forth from 15.5-16 mpg. I did take a long highway trip and got to see how it ran on the highway. I was from the Allentown/Bethlehem/Easton PA area "Lehigh valley" down to lower Delaware and back and it jump up to 20 mpg so I was happy about that.
