Removing the S&B cover

[Mike Hickman]

What would it hurt to remove the cover over the filter housing other than a little more dirt ?

just asking, but wouldn't you pick up a bunch of heat from the engine compartment? Wouldn't hotter air affect things like EGTs or some performance? Isn't the idea to have as much cooler air going in?

I'm just throwing it out......

Cool air is good?

I was under the impression that cooler air is denser so it helps the truck perform better. No? I certainly could be wrong.

Asking because I seen a cold air intake straight from the filter with no filter housing on a 7.3
It seems the hotter it is here in south Texas the better mpg I get , weird I know. Anyways cooler air seems to be best ?

There already is a gaping hole in the side if your talking about the S&B filter for a 6.0

I have tried this with mine and I didnt notice any difference at all.

You do pick up more heat when you are stoped at a light but once you get moving IATs cool right down again

Yes for the 6.0 just used the 7.3 video because that's where the idea came from . Thanks guys.

Geez, I don't believe I just quoted myself. The above post was funnin'. Yes cool air is an improvement.


The reason the diesel runs better when it is hot is because it is a compression ignition engine and they like heat. The air temp allows the overall engine temp to warm up and they run better.

That is why they make a 203* thermostat for the 7.3. We are stuck with our 192*.
