yep, which is partially how the IAT adjuster makes power... colder air
temps can vary timing +/- 3 to 4 degrees. (measured by SnapOn 2500
scantool, as well as OTC 4000E)

In the summer my R/T runs pretty well on 87 but in the winter it will knock
unless I use 89. Could it be that cooler air in the engine causes more
spark advance?
