My truck drives like a dog in the summer and I think it is because of the K&N cone sucking in too much heat from the engine. So I am wondering if anyone has combined the K&N tube with the stock airbox? They look like the would line up pretty good..

If I did this I would use Motorcraft FA1658.. I don't like the oil mess..

 

Ive seen maybe 2 or 3 people on here do this. Ive actually been thinking about doing the same thing.

 

You could also make a custom tube out of some aluminum piping and a couple fittings. There are online stores where you can buy all the pieces you need.

 

He already has a KN metal intake tough!

FX2.3, just ditch the KN thing altogether. My truck runs great with just the stock intake, and the intake air temps are about 15* cooler than they were with my KN 77.

 

I really don't want to put this massive thing back in:

 

lol, that looks worse than the 4.0 intake!

 

x2

That thing is almost as bad as a 5.4L intake on an F-150.

Can't you make a heatshield for your cone filter?

 

I've done it with chrome mac intakes on a 3.0. It fits right in as long as it is 2003 or older.

 

It oughta work, and with the air box mod, prolly flow almost as well.


OR.....you could give me that intake tube, and I'll give you my stock tube that doesn't have the muffler box on the side.

 

uh no..

 

Darn. Worth a try anyway.

 

i'd say build a custom box around your filter

 

Get some Lexan/plexiglass and build an enclosure for the intake.
