Just curious what people are running as a majority. I heard when I owned a 7.3l that the 6637 was the preferred filter to use for two reasons. One, it was cheap and two,it had a metal mesh on OD AND ID. Many of the guys claimed it was les chance of filter getting wet, tearing and getting sucked into the turbo. Bad news. I just picked up the recommended 2790 which is a bigger diameter 10.5" versus 6637 which is 8.5", but it does not have a metal mesh I'd. Just paper on I'd and mesh only on od. Just curious if anyone has seen any problems with the 2790 collapsing. I'd also like to know what cfm each of them flow if anybody knows! Thanks.

I never had a problem with any of the bhafs until approx. 600whp.

Thank you for posting that spec.

 

I've been running the standard BHAF for years now and never a problem with getting wet or falling apart. Several times mine been wet from heavy rain showers or puddle jumping in the back roads.

I have been running the 6637 with no issues for several years. Bagwan??? not familiar with that term.

I just put on the 2790 the other nite and wow did it make a difference! I really think it helped turbo lag a bit but I guess it could be in my head but sure seems like it helped the low end a tad. haha. As if I need more low end! I ain't complaining! lol.

Haha. I just realized I had a typo on the header for this post. I was wondering what the heck you were talking about!
