Thread: cold air intake curiosity

so basically when people say they are losing 2-3 mpg its just because theyre a little more heavy on the pedal? damn people dont know how to get accurate results.

If i do a DIY CAI with a good filter though (or even an average filter for that matter) the setup itself wont lose me a significant amount of mpgs? Im sure theres some flaws with DIY CAI's.
