1/18/23: I splurged on the stiffest strongest filament I can reasonably print, 3DXtech Carbon Fiber polycarbonate.
This is several times stiffer than pure polycarbonate, and stiffness made a fairly significant impact on sound.
Got tired of my K&N running funky and decided to 3D print a MAF housing to perfectly transition from a velocity stack to MAF to OEM elbow.
Result: It no longer wavers at idle!
Bonus, WAYYYY larger surface area (Part: aFe 21-91035), and a smoother transition into the MAF.
Was super happy that the MAF opening design I did made for a perfect friction fit with the O ring and the offset amount on the screws was perfect.
Sound is slightly so different from the K&N, similarly loud but a tad more sonorous?
Next steps:
- I accidentally offset the MAF screws backwards in Fusion towards the elbow instead of toward the intake, so will be reprinting with that fixed.
- Am also waiting on a CF bellmouth (Part AF64-4971) to come from Australia to shave down a bit of weight and have an elliptical bellmouth profile vs the circular on this cheap Spectre (Part: Spectre Performance 9605).
- Will try for a silicone elbow, too. The flex in the ribs are actually pretty nice actually!
- Redo the air blockoff because between the CSL SMG fluid tank and this new filter, the K&N shield isn't even close to fitting.

Quick pic, feel free to laugh at my awful sense of direction on both the photo and the maf screw offset.
