What does BHAF stand for? Does anyone have a part number and source. Also a photo how you have it installed would b great.

 

big honking air filter.... I cant remember the napa number any longer seems it 2790 or something like that.

 

I have the Wix on my truck, p/n 42790. Napa is 2790

They're 10" diameter and 10" in length.

I used a short elbow piece of 4" intercooler tubing from a semi to go from the turbo to the filter.

 

This was immediately after i put the filter on.
The orange coupler at the filter is not necessary, the filter is hard rubber and simply slides over (with some effort) the elbow.

The pantyhose simply acts as a pre filter.

 

Thanks for the pics. I get the idea. You must have relocated your battery?
