6637 filter....
 

have the filter tommorrow morning...now I have been seeing people posting about a piece of 4 in PVC what is this for and also is there a sensor in there that needs to be relocated and if so where to.
Thanks

just zip tie the sensor to something,doesnt really matter. i think it controls the idle in cold weather. someone will correct me if its wrong. as far as the 4 in pvc,you dont need to do that either. just makes for a smoother surface for the air to travel in. you will need to put two long screw clamps together to fit around your intake hose. i took the whole hose out of the truck to squeeze on that big ole filter. it is a good tight fit! i certainly like this setup for keeping the intake clean. good luck

I actually NEEDED a 4" piece of PVC pipe (used a "coupling" piece from Home Depot for 89 cents) to make mine fit and work properly.

I have a 2001 F350 and the intake hose didn't fit over the 6637 filter very well. It would pop off of the filter when I closed the hood. I would DEFINITELY get the 4" piece of PVC pipe (coupling pipe). Just bring the 6637 filter to Home depot and tell them you need a piece of PVC coupling that will fit INSIDE the filter hole. It is a tight fit and you don't need a clamp to hold it onto the filter. You will need the clamp on the intake hose.

When you hear a sound like "Darth Vader" breathing from your engine when the tranny shifts from 3rd to 4th...you'll KNOW you did it right.

You didn't clamp the filter to the intake? I would think that it may vibrate loose. Most are using a 4" rubber "no-hub" style coupling on the filter. Do you have any pics?

Let me clarify - I did clamp the intake hose to the 4" PVC coupling piece. That needed a clamp, but not on the filter side at the PVC coupling.

I can get a pic tonight. It is NOT vibrating loose...that I can tell you. It took some pounding to get it in the filter, and I sealed the edge (just to be safe) with plastic weld. It's a very strong and tight fit.

I'll snap off a pic tonight and post it tomorrow.

cool, I'd like to see that.
