I have the Volant with the ram air tube and I'm very happy with it...it was a bit pricey but it's of good quality and a nice looking CAI. I'm currently running my IAT sensor in the stock location in the MAF, but may eventually relocate it to the EGR block off in the intake.

Iat temps make a huge diff. if you have some tuning software such as hptuners you can see that many chevrolet trucks start pulling significant amounts of timing at about 95-100 degrees the timing amount pulled gets higher and higher with intake temps. In FL we see temps in the high 90s all the time

Unfortunately I don't have tuning software, and my scan tool doesn't display IAT's IIRC (haven't used it in a while so I can't remember lol). Sorry I don't have any help for you there

I got a cheap ebay cai, today i was watchin it in a fast food line since it was kinda cool today, 65* out and it got up to 95* while sitting and comes back down when u get moving obviously. Mine even touches the coolant hose a little so the tube gets a little warm, but thats after the maf. From what ive read the air moves thru so fast the actual air has no time to heat up, but your maf sure will. I would relocate the iat and call it a day unless u want to build or buy an absolute enclosed filter setup with iat inside i dont see it changin..

Maybe not the best for extracting all out HP but ill bet you dont lose 1-2 hp.
Not really!!
Hotter intake temps increases the burn rate,when the burn rate increases spark must be pulled.Unless you just zero out the IAT correction table like some do.Not good!!!!!

no way i would zero out that table,then i would be buyin a motor
I have noticed when it gets real hot take off more than half throttle you can hear some spark knock then pulls timing and no knock
