I want to change out the stock air filter for the Napa 6637. I called the local dealer and they want $50 plus bucks for theirs. Where can I order the filter and any plumbing I need on-line?

Thanks

 

Here is the filter fleetfilters.com
Most people use a scrap piece of 4"exhaust to connect it up.

 

You can try NAPA and tell them you want the AAA discount. It may help some.

 

I just used heating duct to go from the stock rubber to the new air filter

 

All I used was a 4" 45 deg PVC street elbow (one end male and the other fem) and a 4" rubber coupling, I think it is for conecting sewar pipe, fits great, and the 6637 filter, and they are more$$ that stock. heres some pics

 

http://http://www.fleetfilter.com/St...cts.asp?Cat=53 Filter for about 30. If you have the old orange hose that goes to the turbo get one of these Silicone 45 Degree Reducing Elbow 3-3/8" to 3" 1820102C2: Intake Hoses, IntakeTubing, and Intake Clamps Pricey but looks like it will last fore ever and ford dont make them any more. O, yea they have the 45 pipe too......

 

Nice set up. Your right about the rubber coupling. It is used for sewer pipe it is called a Fernco coupling.

 

I used <a href="http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=470&LineCode=EXH&PartNumber= 41615&Description=Exhaust+Elbow">this</a> elbow from NAPA. Perfect length and angle for my set up.
