E-Series VansTechnical discussion of topics related to vans powered by any of the Navistar engines. This covers a broad number of years, but there isn't enough demand to split it any further.
Hi guys, I have an 03 E350 7.3 PSD. I was wondering if any of you know what is the box that is in between the air box and turbo? The intake tube tee's off and goes to this box which is mounted right behind the fuel bowl. I cannot see anything that goes to this box. Have any of you replaced the factory intake tube with a tube that runs from the air box straight to the turbo? Thanks, Nick
it is a resonater box , you can remove but most guys report an anoyying drone noise when they remove,Wade

Some resonate......some don't.
Mine doesn't do it at any speed.
I pulled mine after the first couple of times trying to work around it (like it's not tight enough without it [img]/ubbthreads/images/graemlins/smile.gif[/img] ).
The second time I pulled it out.......just decided to cap it off and see if it resonated. Never did.....so it just stayed off. It does make it a bit easier to move around in there.

Seems if you have the newer style turbo wheel its not to bad.
Change over was 98 or 99 don't remember.
Mine is old style (97)(WW). Makes alot of intake noise.
I would love to toss it.(resonator)
I also will cap mine with 2" abs pipe when I upgrade my Turbo intake tube with the hard Black rubber deal I found on Ebay , instead of the orange soft rubber crap. I don't understand why they put such retarded stuff in the vans in the first place. I also installed the WW . When the gatto takes a permanent vacation and I get my PCM flashed it will be a big improvement . I don't care about noise since My Ladders make lots of it. Whoever designed that stupid box should be crucified worse than Jesus.

That orange tube must be on the older vans, I have the black tube in there. Couldn't you just get a piece of hose to run right from the airbox to the turbo bypassing that stupid resonator box?

The reason I upgraded was my compressor wheel was really nicked and Jeremy @ LIPD made me a deal I could not refuse for the upgrade so I did it . . . the price was right. [img]/ubbthreads/images/graemlins/grin.gif[/img]
