do you really think that this will improve Volumetric Efficiency or reduce suction throttling loss

shake your head no

do your really suppose that there is there any way that your tampering can improve anything ?

shake your head no

why do you persist with what you have been shown can not function As you desire it to ....
you can not "hope" for an improvement , you must operate in
reality , unlike our current government

Made of a heavy plastic funnel...just forced it into the corrugated part of the intake tube after the MAF.


Opening in cone is around 1 1/4"...which is approx the same as a half throttle opening (45*) at the throttle body...so in most situations it just acts like a dirty filter ABOVE a certain throttle opening? Used around .61 square " per L from above posts as a guide.

Scangauge shows high mpg for first mile on highway after leaving town...but it settles down after that.

Will reinstall and test next summer.
