I know there is the Black Mamba DIY writeup, but if you don't have/can't acquire an airhat
like I couldn't, this write up is a solution. Now I can't say anything about better throttle response or MPGs, I'll leave that up to you.
The main purpose for making this was to utilize an airhat that steered clear of the throttle linkage.
My old K&N hard plastic intake prevented the throttle from fully opening.

-----------------------------------------------------------------------------

The total cost for this is around $50, not including a cone style filter.

I ordered this intake hat. It's made out of thick rubber and fits very snug on our throttle bodies and held in place with a 5in clamp

Since the outlet on the rubber air hat is 4in outlet,
I picked up some albows and straight pieces.

Mock up the turns and pieces starting at the airhat and going towards the area
where the radiator meets the headlight on the passanger side.
This is where I found the most room for my larger sized filter.

Once you have the turns and angles generally in the right area,
mark the PVC with a sharpie so you know where to glue the pieces together - I used this stuff

I'm sure yall are aware of rerouting the intake air temp sensor from the manifold to the air intake.
Skip this if you keep the sensor in the intake manifold

After the glue has set for a few minutes, I drilled a hole about 6 inches away from the airhat into the pvc,
then used a bolt to start the threads because the sensor is made of soft brass threads. Gently
screw the air intake sensor into the PVC

I wrapped the tubes in electrical tape to hide the ugly PVC. It could be painted at this point as well.

Finished product.

Future plans include making a box to keep it contained near the front of the engine bay.
Also a way to dam air from the grille area towards the airbox
Air Ram has some air streams like these that I'll be copying/using

Total cost:
Rubber air hat - $40 shipped
PVC parts - $10-$15 (depends on how much you use)
Glue - had in the garage, probably not more than $10
Large clamps - $5

Ah yes that little cloth piece - took that off but the picture doesn't show it from that angle. I'll get more pictures soon.
