As the temperature during the day around here has hit the upper 90's and low 100's with the heat index I have noticed a slight drop off in the performance of my car. It doesn't like the heat!! lol After sunset when things cool off a bit the car runs like it's normal spirited self. I know that colder air makes better power and it's not unusual for a little loss in performance during very hot temperatures. I just notice it more in my Mustang than I did in my Jeep because the Jeep was a dog and the Stang is obviously more performance oriented. I feel sorry for you guys that live in places like Arizona and New Mexico where the temperature can get really hot. Now I'm considering adding that Ford Racing CAI kit to see if it helps any on these hot days.

I've noticed the same thing. Upper 90's this week.
Kinda hard to suck in cold air when it's so darn hot outside.

Just good ole heat soak...

The temperatures probably effect more than just the 4.0 engines, no one else has said anything about it, the cai will help a little with these temperatures. I also believe we here on the east coast have it worse they don't have to worry about the humidity like we do, they have more of a dry heat out west.

A stand alone CAI, won't do much performance wise. However, a CAI with a custom tune will definitely help with the sluggishness during the hot summer months. ;-)

Agreed Obxdude, the humidity only makes matters worse. Today it was 107 hear with the heat index and about 80% humidity. Blaaeeh.

Has anyone here put on the Ford Racing CAI and if so what did you think?

yeah heat is the enemy for sure. My car has not felt right since like april, good ol new mexico

in addition to a cai , you need to relocate air temp sensor to intake manifold , so you get a true temp reading , no doubt your car is pulling timing due to weather heat and engine heat / note sensor in front driver side intake runner

Yeah, the S197's heat soak something fierce; V6 and V8. Not something we weren't aware of, though. Turn the A/C on and it feels like my SUV hauling the boat.

Use of a lower t-stat in the v6 will help. It definitely helped my setup when I had a Vortech blower as well. But you'll want the cooling fan temps lowered to come on as well

I put a 180 t-stat in instead of the stock 192, and would at most hit 190* coolant temp. The ecu normally will pull timing with excess heat, and this helped.

But not a lot you can really do, except wait for cooler weather!
