Custom Homemade Intake For My GTA

Well, looking at my current stock intake for my GTA, I thought to myself, this plastic, boxy intake HAS to be restrictive compared to a straight intake, So, I got to thinking about making my own, and I did.



This Intake Is Made Of The Following:

Heavy duty rubber coupling, 4x3 Inch
Heavy duty rubber 90" elbow
PVC Pipe
Rubber Downspout Connector (To connect to MAF)
45" Plastic Elbow
K&N Filter
Plenty Of Hose Clamps So Nothing Gets Loose

The last step to this intake will be a new K&N filter, mine on there now looks like its time for a replacement.

So? What Do You Think? Is It Better Then The Stock One?

Im open to all opinions.

right concept but it looks like a plumbing fixture with an air filter.

Who cares what it looks like? As long as it's an improvement in flow, it's an improvement. Is that the MAF just before the long sweep ell?

It doesn't look bad, I don't think it looks awesome either, but by no means does it look bad.

Good Job.

other than the writing on the white piece of pipe, I think it looks good. Sturdy and solid.

Very nice, should flow well too.

PS my buddy had one made for his t-bird s-coupe, it was an aluminum tube, bent to shape. If it was 1/8" off (and it was), it was HARD to line up and fit right. That plastic should work great.

Thanks for the comments, and about that white piece of pipe with the writing on it, that piece was just there to prop the intake up, not as part of the intake.

Not really going for looks as much as better flow, but hey, it dont look THAT bad

The MAF is Right behind the Filter and the 45" plastic elbow, right on top of that "Plastic piece of white pipe with writing on it"

It would look good if it was hidden inside a fender or something…

The real problem with those plumbing fixture setups is that real world, every bend and every not totally smooth joint is a restriction… with all those joints I’d bet that it doesn’t flow significantly better then stock, crappy intake.

You're right...Smooth tubing is just as bad as flex, stock tubing...

Only thing I'd change is, some kind of box for the filter itself, to prevent it getting hit directly by water and bugs.

Nice job!

If mine wasn't MAF, I'd custom build a t-shaped air intake.

I'm trying to figure out, if there's any way to utilize the stock GTA hood vents on a MAF system.

Axle/Gears: huh?? guessing stock.
gotta love teh home depot speed shop!

now if you get brave, take that to an Exhaust shop and see how much they would charge to bend it out of pipe. probably not much, and the inside would be smooth and not as restrictive as all those joints.

I just realized....

You made it to go straight down, behind the rad, huh?

I've been thinking the same thing. Maybe a deflector, so the hot air flow from the rad, goes around the intake tube. Then again, after 10 min of driving, the heat wouldn't matter.

You'd have to find a good shop that has large piping (3" - 3.5" or even 4") and can do mandrel bends since not all can do pipe that large. Also, get it ceramic coated to stop the heat soaking.
