CAI and Egr. What’s the point?

K&N makes a cold air intake for the vulcan v6, but it seems to be worse off then the stock intake as it (K&N) draws right out of the engine bay. How is this considered a cold air intake? Furthermore, if the egr is open it’s drawing extremely hot gases right off the exhaust headers, heating even the warm air already flowing in. I’m beginning to wonder if an egr delete would help the stock air intake draw cool air better. I’ve placed my hand on my aluminum intake and it is often too hot to touch.

Is an egr delete going to help keep the intake cooler?
Do the K&N cold air intakes really help or is it just a scam?

They start with this for the newer trucks that actually make some sense and get progressively worse with the older trucks until you’ve got an air filter that draws right from the engine bay.

They’re also stupid expensive.
 
You're right, 99% of aftermarket CAI kits are in all actuality HOT air intakes. Most people shouldn't waste their money on one.. especially if it's for a truck.

The intake manifold is always gonna be hot though.. regardless of whether it has an EGR or not. Its bolted to the heads. Heatsoak is the enemy.. not a lot of good ways to kill it however.
 
Fact is, most Fords come factory with what is essentially a CAI, since the air is ducted from behind the headlight into the air box.

EGR isn’t quite the enemy either, the whole purpose is to inject hot exhaust gases that may contain some unburned or partially burned exhaust gases into the intake under certain conditions, like full throttle. Well, I mean, if you have an early 2.9 that has an EGR, those didn’t work great from the factory and they were unnecessary on the 2.9 which is why they went away in like 87 or 88. Those EGR equipped 2.9s though got the bigger throttle body.

Catalytic converters aren’t a problem either. As long as that stuff is working properly, it’s not hurting anything. What is harming performance is that automatic transmission if it’s un-modded and the bands haven’t been adjusted in the last 50k miles.
 
My factory intake 2002 F-150 intake was generally within 10 degrees of ambient... 10 degrees wont make a bit of difference.
 
The K& N model is used primarily for applications that the owners will use a high performance chip imbedded in a card that will allow the transfer of funds directly to K & N's site to boost their profit margins by giving the owner a shiny plastic and metal device that looks cool in their vehicle. Also does not filter as well as the paper filter and system placed by the company that designed the vehicle...

But it does look cooler...
