I have been fighting with getting Transfer Function tables for different Cold Air Intake kits. I posted on another forum and someone gave me the formula to figure it out for any size CAI. So I made a spread sheet using the formula for every size from 80mm stock to 100mm. I also put several manufacturers of CAI kits on the first page with known sizes. If the size was not positively known, it was left out. I grouped them by size.
Simple to use. First page tells you what to multiply each value with to get the new value. But at the bottom of the page, it is already done for you. Just click on what size you have and the Transfer Table is there.
Hope this helps someone else and saves them the troubles I had trying to get this information.
