Review on Boost Performance with Airaid 300-637 PowerAid Throttle Body Spacer by Larry Gaines

2018 JLUR - I went from 17.5-18 mpg before install to 20.2 after install. I average 19.3 just driving how I want without paying attention, but that's still a 1.5mpg difference. I drive on the highway / city, on a normal lift and tires. I said 5 stars for the value because I get my money back within the lifespan of my ownership. This time the part I put in my jeep gives me my money back. It doesn't seem to be a problem. I also installed a K&N 63-1576 performance intake system with a rotomolded housing.
