Description

PDF

This was a quick way to remove the obstruction of the MAF sensor for when you have switched to Speed Density and the MAF sensor is no longer needed. Designed in to parts with for ASA and attached with slurry.

 

Modeled to take Cobb or similar filter. 

 

I struggled a bit with seams, so needed to be sanded out and smoothed with acetone. Having those dialed in would have saved a bit of work for sure. High heat area, so make sure material is choses as such.

 

Tube printed with outer brim, no need for supports. Plenum needs supports for inner recess only.
