i know people might hate on me for asking this question but im used to speed density.. i saw on buschur's product page that their intake isnt recommended unless you are speed density. why is that? i know if you dont recirc the charge back into the intake you will have some problems, but it looks like the factory intake with a different filter and a metal tube. i might be overlooking something obvious. im guessing it throws off the maf? any input would be appreciated.
