Questions on HallTech CAI Induction system please
I tried to download the instructions, but couldnt. The description said that 'some cutting' is required for the CAI option but NOT the shroud ; can someone tell me exactly how this CAI is installed on the Halltech filter which appears to sit in the engine compartment ? Also, how much is the air filter replacement ? I was just about to buy the Vortex Rammer system when i came across Halltech. Thanks, Dave. 2006 LS2.

I have purchased the Halltech with the CAI. I am in the process of installing it right now. The short is...the CAI replaces the lower shoud. This lower shoud is the plactic surface on the bottom just inside the grill. If you look closely at the grill area of the stock C6, you will find that on each side(left & right) behind the grill there is a vertical plastic surface. On the CAI this vertical plastic surface has a 5" x 6" hole cut out of it, and a wire mess is placed over the back side to form a grill in the hole. It would be very easy to modify the stock lower shoud by cutting these two holes out on both sides.

P.S. I still think it would be a good idea to cut open those end housings though so ram air can hit the lower part of the engine as it goes past the sides of the radiator -- GM should have come up with that idea.

I dont think this is a very good way of getting cold air to the Halltech Filter because the engine bay isnt sealed on top of the radiator to prevent engine heat from getting at the filter. Agree ? What exactly comes the Halltech CA Induction kit for $129 ?

I've had the Halltech CAI on for about 9 months. If you relocate the inlet air temperature sensor to the area by the filter intake, you will see that the temperature there is almost identical to the outside air temperature, even in hot weather. The Halltech filter is well positioned and water ingestion is almost impossible. I have driven in strong rains with no problems. As stated before, it would be very easy to modify the existing unit to accomplish the same effect. Be sure and put some type of screen on it to keep out the leaves and trash. Besides, it looks cool!!

Im going to take mine out and cut my own holes then reinstall them because i can see that it would blow good around the lower half of the motor. As for the Halltech air filter sitting above the plenum , there wont be much improvement ; the air filter needs to be in a sealed box who's bottom side is cut into the plenum -- in fact since i work with sheetmetal all the time in my trade, im going to make a sheetmetal box for the Halltech to go in then tap into the plenum for 100 percent cold outside air. Ill paint the sheetmetal box flat black so it looks nice and make it easy to remove for when i need to get to the filter. Question : Can you please tell me the approx. dimensions of the Halltech filter so i can get started before it arrives ? Is it larger than the Blackwing filter ?? Thanks much. Dave

dave, did some temp testing today and here are the data on the cai if you want them.
outside temp 65 degrees
temp under the hood when car is cold 65 degrees also
drove it for 5 miles, outside temp 65 degree still
under hood temp 65 degree also....
after parking the car for 1hr 5 minute while at the gym, under hood temp climb up to 107 degrees.
started the car & headed home, 5 miles later, outside temp 62 degrees.
underhood temp 62 degrees also.
so it does appear these 2 holes are helping keeping the under hood temp close to the outside air temp....as good as the bottom feeder, just missing the ram air benefit.

too late now, i have a custom grill behind the factory grill, it would be too hard to tape it up....yeah, i will take you on your bet, any amount you can handle.....just to help you out, before the holes were cut when you get done driving and pop the hood open you will feel the hot air coming out...not no more after the holes were cut....you still want to bet?

Ive also considered drilling two 1" dia holes directly under the Halltech filter in the top of the plenum which would have a bit of ram air hit the filter directly --- but perhaps this isnt necessary now since the air filter is the same temp as outside.
Thanks for your temp feedback. Very encouraging indeed.
