ait intake/exhaust.

[newlystroked]

Hey guys new to owning a powerstroke. Does a cold air intake and an exhaust really help with gas mileage also. I know it helps with power. If this does help what cold air intakes and exhausts do you all recommend. Looking for the best bang for the buck. Thanks for the help.

fuel mileage im going to say its iffy. esp since it will sound soo much better your going to want to keep your foot into it to hear the exhaust and intake... but it will lower your EGT's and give you a lil more power....

as far as what to go with i would go with a S&B intake like this: S&B 7.3L Intake

and if your not looking for a SS exhaust our budget kit: Stealth 4 & 5" Budget Kit

if you have any questions please feel free to ask

Mileage, performance, and sound will go up w/ a good intake and exhaust.

Dont do any "cold air intake" crap on your truck. Just grab a napa 6637 filter, and do a straight pipe.

Both of those will be sufficient unless you breach 400+hp. Then you'll want a bigger 4-5" exhaust.

I get like 4mpg better w/ the intake and exhaust.

Why not do a cold air intake. Not necessarily the cold air part but a bigger filter and tube should help right????

Well ya a bigger filter like the napa 6637 would help 10fold, but a true "cold air intake" doesn't do **** on a turbo app anyways, since the second that air hits the turbo it's instantly superheated anyways. But yes a bigger filter that straight up allows more are in, and more efficiently, is definitely where its at.

ok yea i understand what your sayin there. Do you know if that napa 6637 will clamp to my k&n pipe? Ive been told to do away with the k&n filter but i really dont want to take the whole intake out.

[85_305]

depends.. have any pics? The 6637 is HUGE and will ONLY fit where the stock intake box used to be. You have to remove the lower box for it to even fit in there. As long as the k&n piece goes to where the stock box belongs it should fit.

But get rid of the k&n filter.. they are garbage. Of course, you can leave it in and have it do the same thing the one in my truck did before I bought it

[newlystroked]

my air box has a sensor in it what am i supposed to do with it?

[85_305]

Just let it hang outside the intake. It doesn't do anything.

ill check and see...i believe someone told me that it would clamp right up in a previous thread
