I ordered a BHAF from DAP and it came on Thursday. Been busy running back and forth all week. I've always been basing the filter change on the filter minder that I typically always just drilled a hole and stuffed the grommet in and the filter minder. I'm going to walk away from that method and start moving over to yearly changes of the air filter. I can't say right now if there any impact in MPG numbers or not but you sure can hear the turbo whine now compared to with the old filter. I'll keep you all posted. 

How many miles/years did you get out of the last one

I thought about drilling a hole in the elbow and putting filter minder in there, so you don't have to drill a hole in a filter every time.

Basing filter change on filter minder...

 

For many years my filter minder said every is OK.  Pulled cover one day and filter had mold on it.  Lesson learned for me
