Default DIY: $10 Ganzflow-esk Intake

I had been looking around for this intake and I had seen earlier models that were very crude and I thought I could do something similar with some stuffs at the Home Depot. I am not sure how people would actually be interested in this, but just around if anyones wants to try it!

I picked up a 2" x 2' piece of black ABS plastic tube and 2" 90 degree rubber hose with hose clamps, in the plumbing section at the Depot!


Tools:

Ratchet
10mm socket
12mm Socket
hacksaw
flathead screwdriver

1. Remove the 10mm bolt, the 10mm nut, and the 12mm bolt holding on the
intake. Then Remove factory intake, but not the stock torque box.

2. Cut Approximately 2" off of the tube, it is just a bit too long.

3. Not needed, but I had a small peice of 5/16" hose and I cut a slit in it to line
the edge of the hole.

4. Put the 90 on the freshly cut tube, stick into the hole and put the other
side of the 90 on the stock intake.

5. Enjoy!


I didn't notice any crazy substantial power but the car definitely felt like it breathed better. I like the way it feels. Hell, for 10 bucks you can try it and not worry about breaking the bank.

i have this done as well,

only difference is I used a straight rubber connector and a plastic elbow that i cut at a specific angle since the angle between the fender hole and the torque box is not a direct 90*, this ensures that the diameter of the intake tract does not change.

also, the pipe may rattle in the fender hole even with the padding when you start from a standstill, for the time being i stuffed a piece foam in there to ensure a tight fit, no rattles.

I was thinking of that myself, but I did this late last night and this is the beta version, if you will. This was about as cheap as I could make this and still look a little decent. I figured the stock was pretty restrictive so a little bendable elbow couldn't hurt! Not to mention if there is cheap asses like myself out there that had 10 bucks to burn and about 15 minutes, this was for them

this is a MAP car, the filter is in that box at the top

the pipe is independant (i was also thinking of putting a velocity stack at the end of it..)

Gooshin is correct, the filter is in the box, utilizes stock filter. Just need a little something better than stock to help her out.

Velocity stack sounds like a good idea! Just an idea, you could heat up the end of the tube and try and try and flair it out to save a little $$$. Just sayin, lol.

Thanks, man. I couldn't justify $130 for a brand new Ganzflow when I can do something similar for a heck of a lot cheaper. Version 2.0 is complete, need to get some pics though!
