I have the Bosch unit. Only 8hrs run time on it - took the screens off. $100 shipped.
Entire intake you see here is $160 shipped. The K&N filter has the same 8 hr run time on it. Air can is opened up for more air.
All is done. After changing both my relays, the wiring pigtail, and the MAF sensor itself, my check engine light is off for the first time since late June. Thanks for your interest but the search is over, for now.
