Installed CAI now Higher IAT????

im a bit confused, because its a steeda CAI I bought off here, and it fit perfectly, Im in love with it, and the sound, but my IAT went from mid 100s to 120s...Now I live in West Texas, and its HOT out, but I thought I would see temp drops. Its an amazing mod combined with the BBR 91 Octane tune, its a different beast. So any ideas why my IATs are raised???

The only thing its missing is the gasket to go along the top to seal better on the hood, but being it came off a 12, I didnt expect it.

That gasket is supposed to seal off all of the hot air in the motor away from the CAI, and seeing how hot air rises, all of the air you are drawing in over top of the heat shield will be the hottest air under the hood. Is that a good explanation for higher IATs? Maybe not, but I would definitely start there in trying to lower your IAT's.

You can also block 90% of the motors radiant heat with some Heatshield Thermaflect cloth. It looks like crap, but it works.

I just don't get when manufacturers call something a cold air intake but they're getting air from under the hood (where it's hot). I had a CAI on my Speed6 that actually got air from the wheelwell (had to take of the wheelwell liner to replace the filter) - that really lowered my IAT...

This kit uses the factory air intake, so it's supposed to be ambient temp air

That's the epic irony of "cold air intakes" for 10+ mustangs. The stock setup is a sealed box with induction from outside the engine bay, but somehow it's an "upgrade" to defeat that.

cold air or more air

As i am getting ready to install my CAI in Texas also. Is it really doing more than allowing more freedom to suck air?

With that in mind, wouldn't changing to the "tune only" intakes with the larger tube make more air?? Maybe increasing performance a bit??

Basically, no. It will allow cooler air, and a more 'free flowing' design, but all that means is still, more air. Which in turn, means, more fuel, then more POWA!!!

Maybe, but many of us (myself included) feel that the stock air tube and MAF housing are sufficient for most NA power levels. It's a hotly disputed point, I encourage you to do your own research (on more than one forum) and come to your own informed conclusion.

My question is it worth having an after market CAI with the Boss intake? Cause I either have to buy the 200 ish kit to fit the roush which uses the stock inlet tube or upgrade to a different CAI.

Got a recommendation on that?

I have a stock boss inlet from the CAI to the tb if that's what you're looking for, I'll hook you up with it

My IAT with my c&L cai while parked in my driveway for 5 minutes. Oh yeah, it's also 93 degrees out too. And I just got done driving for like 30 minutes.

You can get just the tube from the Ford parts counter if GB doesn't have what you need. It should be $50-75. I just don't think you need more airflow unless you are really pushing a NA motor. Maybe if you had heads, cams, longtubes with offroad mid you would see some small gains from a larger inlet/maf housing. Maybe.

he does thankfully, I didn't know I could get it from Ford, I would still do that over a 200 dollar kit. I just figured if I was gonna spend 200 might as well spend some more and get a complete CAI instead of the half assed roush I have.

The kit that I got the intake tube from had the purge valve relocation bracket as well as the line needed to relocate it, and a new fuel line. The new fuel line is EXACTLY the same as the stock one. So the only thing I used out of the kit was the purge valve relocation bracket as well as the line, it personally bugged the crap outta me to have the purge valve just laying under the boss intake so I rewired it

I made a thread with part numbers and everything like a year ago ... nobody cares.

edit: I can't find the thread so it might be on another forum or buried in another thread. If I can find the pictures I'll post them here or in the Boss IM install thread.

I can't get that image to display right-side-up because iPhones are stupid ****ing pieces of ****. The part number is "CR3Z-9B659-B"

I bolted mine to the block and I'm perfectly fine with where it is. Only people very familiar with the install notice, and usually they comment on how "it's not just hanging there."

That's awfully high! But that's about what mine was reading. I'll have to look more when she's out of the body shop. Damn people leaving shopping carts out.

Picked her up this afternoon, was running 120 on the highway coming home, put the gasket on, dropped on the highway down to 106! Considering it's 110 out side, I'm happy!
