Hey everyone I just joined and this my first post
. I have been doing some reading on everyone's DIY intakes and would like to clear up some things for a lot of people with 6637 filters ive had the same troubles with.
Napa in Oklahoma wants $61 for the 6637. I began to search for the $30 mysterious filters locally. I Did not really want to wait for an order from online. O'Reilly's/Autozone also had nothing in stock but wanted $60ish aswell.
I have a good buddy that works at a Kenworth dealer. Stopped in there this morning and he cross-referrenced the part number for me to a Cummins and a Pete filter. Which initially is what the filter is for.
It cost me $30, had both in stock and it was 5 miles from the house.
Just trying to let everyone know that if you dont know, Try your Local BIG TRUCK PARTS STORE.
hope this helps some people.
