It's time to swap out the BHAF and was thinking of getting the Amsoil nanofiber air induction replacement filter. Anybody try these and like the results? Also need to figure out which filter. Their chart has many choices in the 4" OD. I just want to hook it up to the stock air pipe as I have the BHAF.

You won't be able to hook to the stock tube like a BHAF. What most people do is get the 4510 (EAUU, I believe) and use a piece of 4" PVC. You could also do a 40xx with a piece of 4" exhaust pipe...

I have some extra 4" exh pipe laying around, so do I just get the biggest 40xx? As in the 4095?

Send Duluth Diesel a PM.

If I can help guys feel free to let me know. EAAU4510 is the best bet since SCH 40 4" PVC is 4.5" OD and 4" ID. This 4.5" flange will allow you to maintain a 4" opening with PVC.

If the OD of your exhaust tubing is 4.0" and you need a 4" flange opening, the EAAU4091 is the biggest 4" flanged filter.
