Thread: Cold Air

true....but like i said your not really getting cold air.

When I swapped the LS6 intake on I had to change the angle of the elbow slightly. That in turn changed how the air was flowing past the MAF, and it started to read incorrectly (it was about 5% off). The LTFTs (Long Term Fuel Trims) were correcting by 8-10%, so it was really rich. It cost me about 2mpg and the pedal felt like there was a bigger spring under it (I have drive by wire) until I had the MAF curve retuned. A CAI can do the same thing. But when tuned, you should get better mileage unless you have a bad setup and end up with a Hot Air Intake, as was pointed out above. The out of the box K&Ns usually don't mess with the MAF reading too much, but I've heard a few tuners report having to lean things out after a CAI was installed.
