6637 DIY Intake filter install/change

[STROKED_NY_023]

So I decided to do a quick write up on the 6637 DIY Intake. I have been seeing a lot of posts regarding this mod and I needed to change my filter anyway.

First you want to remove your stock airbox from the intake tube.



Next you will need a 4" 45° elbow. A muffler shop should have one, if not you should be able to pick one up online for $20 or so. Another option is using a 4" pvc street 45° elbow and a small piece of 4" pvc. I used an exhaust elbow. You will need to cut it almost in half to make it short enough and get the angle right.



You will also want tp pick up a nice "t" style clamp. I like this style of clamp because you can get it really tight. I used the stock hose style clamp on the intake pipe.

Clamped up...



Installed in the truck...





I really needed to replace mine....

Yeah it is, it had been a long time sense it had been changed... I still have it, i'll try to get a pic of the inside of the filter, it looks as clean as the new filter.
