That?s exactly what I did. My baseline test (stock cold inlet) was over a week and 256 miles. The second test (warm air intake) was also over a week and 263 miles. Results were slightly lower mileage (too small to be statistically significant) and loss of power. Right now I'm in my third test (stock cold inlet back in place) lasting a week and hopefully the same amount of miles. That will make for a true A-B-A test.
