Re: Hawks 4" Air Intake Kit
I’d rather go here and buy the aluminum piping. But that’s just me.

That hawks kit kit seems expensive for what it is.

Re: Hawks 4" Air Intake Kit
I had a 3" pipe system w/ an open filter beneath the sheetmetal (behind fog light) and it was awesome. The company I got it from is still in business, but will not make anymore. Was $299.

Re: Hawks 4" Air Intake Kit
Those pictured all draw hot under hood air. Cut the battery tray and put filter under, behind fog light (on TA) and it draws Cold Air. The one I’ve pictured, I installed in 1991, Worked very well

Re: Hawks 4" Air Intake Kit
The Hawks Cold air kit, 92mm version.
The Hawk's kit a a nice excellent fitting kit. One stop shopping. I think it's fairly priced compared to other aftermarket kits for various cars.
I would buy it again.
When I had a Fast 102 LSXRT intake on the car, had a customer coated aluminum tune set up on the RS and it got hotter.

Re: Hawks 4" Air Intake Kit
I like the silicon because it doesn't pick up as much heat off the upper radiator hose as the thin aluminum would, however it also heat soaks more and takes longer to cool if it does absorb heat off the radiator. Here is mine its a combination of parts, I started off with a ebay intake for an Escalade, but didn't like the cheap rubber boots. So the 90 degree reduces from the intake size to the MAF size in the 90 degree turn (amazon), the coupler from the MAF to the first straight pipe changes from the MAF size to the 4" (amazon) the next coupler came with the original kit, the 45 degree elbow was part of the original kit I cut down to fit. I had a much larger filter on the end from the original kit but ended up with a spectre filter (autozone) that has the outer cone as well as a inverted inner cone on the end so you have alot of filter area.
I need to get a different upper radiator hose or a small extension so I can pull my radiator hose closer to the radiator so its not touching the intake pipe. Ignore the heater hose... I'm not quite done there I'm installing AC right now and then will finalize the routing, but my engine is too close to run the hose down the back side of the engine so it looks like I will have to keep the eye sore. Also the wires in the back pass side I still need to finalize routing and loom them. I think I may paint the aluminum tubing and get someone to Tig on a flange I can bolt it to the wind shield washer tank (where the TBI intake screws on to it). I also want to make a filler panel to box it in so its not sucking hot air in (aluminum with some head shield). I have fuse boxes and the A.I.R. injection pump below the filter as I built it 100% 50 states smog legal... for now... I may remove the A.I.R. and EGR all together since I don't have to do emissions where I live. The IAT sensor I drilled a hole in the aluminum tubing and used the original bung from the donor car. Its on the back side (intentionally) so you don't see it.
LOL the flimsy rubber boot is in the bottom right of the picture.

Re: Hawks 4" Air Intake Kit
I know everyone always says "hot underhood air temps" but has anyone ever logged actual under hood air temps (in different locations under hood) from 0-100 mph? I'm not talking IATs but ambient temps and if/how they change through say 1/4 mile? There has to be some decent air moving through there.

Re: Hawks 4" Air Intake Kit
If you can't weld the tube you could use this.

On other vehicles, I've seen the data. Corvettes, specifically. One airbag test from years ago illustrated this fact when the "gains" on an open element filter assy. on the dyno lost nearly all gained once the hood was closed. The airbag which grabbed air from outside the engine compartment, kept its gains. Hood up or down, didn't affect that one.

Re: Hawks 4" Air Intake Kit
so it looks like my 4" intake that I ordered isn't going to work out, mostly because I am using the truck alternator/ps pump and an adapter bracket which limits the space where all of you have ran your intake. using the intake as pictured will hit the hood. routing the opposite direction will hit the battery. My remaining options are:
1. put the MAF and filter right off of the 90 going towards passenger side
2. run a TPI air intake
any input/ ideas?

Re: Hawks 4" Air Intake Kit
I’m using the truck brackets too and haven’t bought an air intake yet. I was worried about this issue and was thinking maybe 3.5 would provide a little clearance.
Whatever you do post it it up because I’m basically done with my swap except for air intake.

Re: Hawks 4" Air Intake Kit
While not an LS, I relo'd my battery just like you.
....I'd really want to keep it 4" if possible. I think anything less (on any moderate performance engine) and the tube becomes a restriction, and negates the benefit of lower temps. I'm no engineer, but I've read a few different tests that show this to be the case. Below 4"....might as well run an open element.

Re: Hawks 4" Air Intake Kit
I bought the Hawks 4" CAI because I was in a hurry and wanted something "plug and play". It works like its suppose to. I don't like it. You can see its not a perfect fit either. I never figured out how they expect you to use the mounting hardware so it just lays on the upper radiator hose absorbing heat. I don't plan on keeping this long term. I plan to get a one piece intake tube that fits/looks/functions better, utilizes an LS7 MAF, and insulate it but it's my understanding I'll have to retune for the different MAF.
