Too rigid to work properly. Had a PVC elbow that it slipped over so I tried some exhaust piping and still the same result. The clamp for it is purely for decoration.

This B is huge!! What a difference of airflow! Don’t forget to get your RiffRaff replacement cover to extend life

Would recommend

Don’t get your hopes up when I say this air filter sucks. Bc it’s a damn good thing. I had the 6637 filter on my 7.3 that cost about $40 and this filter sucks way more air and I can hear the turbo much better aswell. I love this air filter plus I can re oil it or re use it unlike the paper 6637. Much better filter for the money would recommend and buy again. Very happy with this product!

In my opinion this is the best filter I’ve tried

Definitely a BHAF! Well made with filtration even on the end cap. Fitted to my AFE stage 2 kit. Extremely tight fit, but it works.

Added this after I got a new KC stage 1 turbo. Had the 6637 on with it for a while. This filter definitely flows more. Haven't had it on long enough to tell for mpgs but I'm not too worried about those anyway. I can definitely say it lowers egts and helps the boost come on a smudge faster. With stock injectors an 80hp PHP with the turbo I couldn't get over 1100 EGT's on a WOT run. If you're thinking about it do it.

I had the regular 6637 filter on my 03 7.3 and after putting this filter on I hear the turbo waaaaaay more. Definitely more throttle response too

Clay shipped my order 18 minutes after I placed my order!!! Awesome customer service and great product!
