To anyone who has done this, can you use the stock intake tube or do you have to fabricate a new one? I wanted to have someone bend a 3.5" or 4" exhaust pipe for the new intake but no one in central Florida can bend anything over 3".

 

i use the stock tube and went to the parts store and bought a piece of tubing at a 45. it seems to work fine until i get the time to fabricate something else.

 

awesome, so all I need is a 4" 45? thanks!

 

works good for me

 

You can hook the 6637 up to the intake hose by streching and it will work. Or use a exhaust 45* to make it fit into the air box area.

 

Umm quick questioin what is the 6637 MOD???

 

aaron its the intake i was telling you about...its basically a diy project

 

there is nothing to it other than removing the stock air box and adding an elbow with the filter. it will filter so much better than the stock air box and increase air flow.

 

Looks like this ...

 

Go to home depot and get a 3" 45* ell it is 4" od clamp it to the existing rubber tube and get a gear clamp to clamp it to the filter works great. Also if u have a fleetpride filter sales store near u they carry Baldwin part # PA2818 same as NAPA 6637 for only $28.00 NAPA wants about $60 bucks for theirs.

 

Ref the above post it is 3" PVC pipe sorry about that.

 

I was wondering if the PVC would work, I know you can do that on the 98+ trucks. Great Info!

 

I cross matched the NAPA 6637 and the matching Purolator is A45090, Advance Auto stocks em and they are only 19.99!! Thought I'd letya know so you can save some money!

 

Thanks for the info, KevinC. Reps sent.

 

i just cut the top of the orig. air box and used that tube
