Hey gang I need help finding the parts for a 6637 kit. I'm on the phone so searching here is p.I.t.a. Obviously I'll buy the filter at Napa, but how do I fabricate the rest of the intake? My current original intake is in poor conditin. Duct tape all over the place on the boot from the box to the turbo. Does anybody here offer a kit that I could swap right in with abs or other plastic pipe etc? Thanks.

 

riffraff diesel, clay can hook u up with something awesome.

 

You could just buy the real Tymar intake... they aren't that expensive and work very well.

 

I ordered a piece of pipe from napa. pipe w/45* bend obviously the same size as the 6637 hole.

 

One easy stop for everything you need.

Riffraff Diesel: 6637

 

Definately go with the Riffraff kit. It has everything you need and just as cheap as you could make it yourself...

 

Well, where is your intake hose all hammered at? if it is the intermediate flex hose that you have to reuse, then you may have to transition to a different setup. Can you provide a picture of your intake? And you don't have to just use the napa 6637 filter, there are a bunch of interchangeable filters, I run a baldwin 2818 because I couldn't find the Donaldson anywhere close... Filter numbers by make are as follows:

Duralite from Fleetfilter 546637, or DC252WA
AC Delco = A1474C
AirRefiner = ARM08-5011
Big A = 94637
Baldwin Filters = PA2818 (~1 inch longer than 6637)
Caterpillar = 3I0003
Carquest = 88637 Cummins = 2912986, or 3912020
Donaldson = B085011H, ECBO85011H, or ECB085011H
Fleetguard= AH1141
Fleetrite = AHR81141
Fram= CA6818
GFF = AF359214 General Motors Corp. = 25177209
Hastings Premium Filters = AF2329 Hercules=B085008
Kralinator = LA1458 Luber-Finer = LAF2533


If your intermediate flex hose is beat up, then you can actually fashion an intake with a longer section of straight 4" exhaust tubing with the 45* bend at one end of it, stuff the straight end down into an aftermarket turbo inlet boot and do the CCV mod and redirect your crank case vent at the same time you do your intake upgrade... kill two birds with one stone. Just my $.02 bud, but let's see a picture to see what your options are

 

How to best go about it depends a bit on the condition of the rest of the intake. The flex joint at the turbo is notorious for going bad underneath and dusting your turbo and engine. You cannot tell it without removing it so remove it and look. Red ones are old style, black is upgraded. The upgrade from Ford is still available last I knew and includes everything from the turbo to the box and includes an upgraded bracket for the valve cover and crankcase vent. I have read that the Ford kit is rather expensive though and you might want to go aftermarket or D.I.Y. My truck had the Ford upgrade so all I needed was a 6637, a $1 3" ID (4" OD) 45 degree PVC plumbing elbow and a couple $2 clamps, done. Some say the 3" ID restricts so I had a exhaust shop bend a 45 from tubing. My engine didnt know the differance. When it started to rust I pitched it and put the PVC back on.

 

Thanks for the suggestions guys. So, the riffraff kit is everything I need? Where does the filter end up? By the fender? Do I have to remove the factory box? What is the Tymar Intake? Thanks.

 

The filter will sit right where the factory box was, and you will need to remove the box. You can just zip-tie the intake air temp sensor to something nearby, it doesn't need to be attached to the filter at all.

The Tymar intake is the same as the 6637, the only difference is it comes with a little mounting ring that goes around the filter but it only lifts it up about a 1/4 inch off the fender. I had one for a while and it was useless.

Follow the link that Clay (Riffraff) put up for his kit and it shows you everything that it comes with.

That is one of Clays kits right? Looks Nice.

 

Ok, ordered your kit! I hope this, and the Diamond eye ss 3" downpipe I about to install give me a few extra ponies.

 

The Riffraff kit is the way to go, you wont be dissapointed

 

I elected to go this route as it was Dales design. Was it worth the extra few bucks?????Maybe or maybe not but I elected this route because I felt it was the right thing to do. Not saying buying the Riffraff kit is wrong its just the way I felt.



I'm under the impression the Donaldson filter is larger than the 6637 filter.....no?



Just about anything is better than the restrictive OE airbox.


But then again WTH do I know I'm just the .


Happy New Years Everyone!
