They don't carry Silicone tubing, just elbows of varying degrees and couplers. The reason being is tubing would collapse under suction. The elbows and couplings are short and supported by solid pipe at each end where they attach to metal or plastic pipe.

Would be nice to have a totally flexible intake system though. You would need the heavy duty metal reinfoced hose like marine Exhaust hose or pump suction hose. But neither is very flexible. You will not be able to make tight bends.

 

That's how mine was. I used a 3" schedule 40 PVC electrical conduit 90 and replaced the hat. Hooked it from the tb to the rubber flex pipe. Then I later used a 2 1/2" piece and fit it into the airbox to house my k&n cone filter. Then I remembered I had a 3" GHL intake from my Gti, so I cut it to fit and cut the outlet off the side of the airbox so the whole intake could be installed with the lid off but I can seal the lid when I drive. If I could figure out how to load a pic id show it.

 

Cool, thanks. I figured it sould be done, it's just kind of a weird angle. Airaid makes exactly what i want, it's a tube that goes from the TB to the stock airbox but it has the proper fittings for the IAT sensor and looks pretty nice. Simple black plastic. The issue is the price, $109.00 every place i checked. Even Ebay. Could not find it anywhere for even a dollar less.

I think my plan will be to buy that tube and install that to the stock Airbox. Then where the stock snorkel is on the airbox, cut that off and cut a larger hole to take either a 3" or (if it fits) a 4" 45 degree PVC pipe fitting in the same location to draw air from the fender area. That should give me plenty of air flow and the ability to use a stock paper filter or K&N. No worries of sucking in water coming into the engine compartment like can happen with an exposed cone filter or the hot air.

When i do this project, i am also going to remove and clean my TB and replace the gasket, install a new PCV valve and install a ground wire to the throttle body. Ill take lots of pictures too.

 

the sensor in the hat is just for temp right? so i could leave it out till i can fit it into the cai pipe?

 

It's the intake air temp sensor. And i would not suggest driving your vehicle untill you install it in the new intake tube. You will likley throw a code and have horrible gas mileage at a minimum. Why would you have a delay in re-installing it?

 

Yes you can....but your engines computer might throw you a CEL.

Use a dipstick tube grommet for a GM Part#65113 found in the Help section of most auto parts stores.Drill the hole just slightly smaller than 3/4 inch, roughly 18mm or .71" pinch and insert.The rubber O-ring on the IAT sensor fits tightly and seals well and it costs bout $5.

 

have had it installed for about 2 weeks. the MPG average gauge went from 12.8 to 15.1 after install. dont know if the gauge is reliable but thats what it says.
