BT223 is just right for D-4D due clearance issues with taller filters. Although I have yet to test fit something like B2 or LF3487 on our Innova D-4D.
As for vvt-i, you can easily use tall filters bec. there is lots of room down there.

OT: as for the blinking optitron, some say it could be the alternator.
How about for my ride mga sir?
