1997 DIY Intake

[scottphillips88]

Ok, I've been lurking around here for a while and have decided to make an air intake with the napa 6637 filter. (seems to be by far the choice on this forum.) It's on its way from fleetfilter.com. Anyways, I haven't come accros any pics of a 94-97 with this mod installed. Also, anything different/unique about the install on the OBS? All of you OBS guys that have done this, please chime in. Thanks!

Here's a pic of mine. It's made out of PVC. You can get some tubing from a muffler shop if you want a metal intake. Its easy, just use what's available. The turbo will sound louder and throttle response will be noticeably better.

Sweet! Thanks for the pic. I can't wait for better throttle response! Anyone with the napa filter on a OBS?

p.s. thanks for the DIY mods on the bottom of your signature pipelayer, very helpful and gives me ideas!

I have the diy intake on my truck with a metal tube. I went to a semi-truck parts dealer and got a piece of 4" exhaust tubing with a 45 degree bend and used that painted. I notived a bit smoother operation, improved acceleration, but the turbo dosent make a whole ot more noise inside the cab until at or above 2000 rpm. I still like it better than stock though.
Sorry no pics.

so, do I need a 45 degree angle on my 4 inch pipe? I have heard both ways with different years of the powerstroke. Just wondering about the 97. and just to clarify its a 4 inch diameter and 3 inches long...right?

for a 1997 you need a 45. for a superduty a straight will work. The length of the 45 bent pipe will be about 10-12 inches or in that area. The 3" you speak of is for the straight superduty pipe.

I JUST WENT TO LOWES AND BOUGHT A 4" OD 45% PVC ELBOW IT`S ABOUT 4" OR 5" LONG TOTAL AND ONE CLAMP TO GO OVER IT. TOTAL COST ABOUT 4 BUCKS, WORKS PERFECT. YOUR FILTER WILL SIT HIGHER IN THE FRONT THATS GOOD BECAUSE THERE IS MORE SURFACE FOR AIR TO ENTER IT. I PUT A SMALL BUNGY CORD ACROSS THE BACK SO IT WOULDN`T JUMP UP. lOOKS GOOD. A CLEAN LOOK.

After u get it installed, get a buddy to come sit in the driver seat while you stand outside with the hood up on the truck.

You really cant hear it from inside the cab, but get him to rev it up to about 3k rpm, then when he lets off, you can hear that thing sucking and blowing like a vacuum! lol

All we did was scrounge up a 45* pvc elbow about 4" OD...take that airbox out and it fits perfect with that elbow

too bad my truck is sick right now!!! I'm gonna post a thread and see if u guys know what is wrong
