Time to do the 6637 filter

[tfifeco]

OK i think i will do the 6637 filter today. From what i understand all it is is the filter and the correct adapter pipe to connect to the turbo intake. I have read other threads where others have used a PVC shreet elbow, i believe i will take this router as well. SO i need to go buy the filter. Who has the 6637 what brand is that and are there any equivalents that i might be able to pickup from a local shop???

thanks

Napa had mine but they wanted $70 for it. I found it online at discount fleet supply for $32 and $10 shipping. I used a 5" piece of 4" exhaust pipe and a hose clamp for mine.


Wishin I was fishin.

I use a Baldwin PA2818.
I also used a piece of 4" exhaust, better fit.
ALSO, I would NOT use a hose clamp. Weak. And when you see how tough and solid the neck is on the filter, you'll understand why. Hose clamp won't hardly squeeze it at all

Actually i started out wit a 4" 45 degree street elbow but couldnt make that work so ended matching up a 3" Std elbow sch40 and wrapped a little black tape to get a better seal. Along with the hose clamps. Seals perfectly, my only concern is reducing to 3" hope there isnt too much restriction. But it is such an easy install that i can always change it out with the right fitting. if i had the right fitting the whole install would have taken like 30 minutes tops. Here are pics

I disconnected the stock elbow from the air cleaner box, put a piece of 4" exhaust pipe trimmed down in the elbow, and used a t-bolt style hose clamp on the air cleaner itself. Easy as pie.

i got a piece of 4inch (straight no bend) exhaust pipe, will it work or does it need the angle?

If you re-use both of the stock rubber intake elbow pieces, you can cut a short section of the 4" pipe and just insert it in the end of the elbow that went to the stock airbox like I did.

A better detail picture. You can see the piece of black tubing between the air filter and intake elbow. The t-bolt clamp is strong enough to clamp the air filter to the tubing but a regular hose clamp won't be.

What do you guys do with your IAT Sensor? Has anyone tried drilling a hole in the pipe to insert it or do you just let sit in the engine compartment?
