2 Intake, not just a cone filter clamped to the air flow meter. that's probably 75% problem with the stalling problem, because
1 not consistant flow through meter, due to the turbo's way of changing air flow quickly vac/boost

I have a 90 degree bend of intake tubing and filter from my friends prelude. Blue silicone tubing between it and the air flow meter including the air temp sensor which is mounted in the center of the AFM
