First of all, you didn't give it enough time for responses. Not everyone hangs around their computer waiting for new questions. Only us retired folks with plenty of time on our hands are here a few times a day ...if there's nothing else going on. I try checking the site as often as possible since I'm one of the moderators but others have better things to do.

To your question. Some of the Go-Fast guys have come up numbers on the different filters but they talk about it on another forum. They have pasted on that using the drop-in K&N filter in the OEM box and doing slight modifications to the box like taking out the white donuts and using a bigger 1/4 round pipe to extract air from the inner fender will give just as much inward airflow as one of the expensive ($200-300) filter kits and it completely seals off hot air from the motor. So, save your money.
