Afe over bhaf???
 

I searched came up with nothing heres the deal I'm looking to swap out my bhaf its due I want to go with something a bit smaller mainly for room I'm looking to swap in a second batt on my pass side winter and camping resons then build a ice box knock off air box just in front of the batt iv seen lots of guys running smaller afe filters on there trucks but never part #s I drive the truck daily and pull my trailer all summer do see gravel a fair bit but I do keep up the maint religiously I'd like to go reusable has any one run a pro guard 7 I know you oil them like a k&n or any other good options ?????

The purpose of the BHAF is increased airflow with excellent filtration. With smaller filters you compromise one or both of those. A group 31 deep cycle marine battery is what I use in my 1st gen. Some people have mounted 2 smaller batteries on the single battery try.

I understand the reasoning for a bhaf that's why I'm running one right now I'd just like to get into something I can run a pre filter with and get more life out of i know im going to loose some going with a different filter. Iv seen bhaf pre filters on the net over priced.

So are you running the flees guard marine??
How are you like the deep cycle with cold starting?

I was going to go with two batts turned sideways on the factory trey but since I did my power stroke intercooler swap the 3 inch pipings just to close to allow

I am running this one DieHard Marine Battery : Buy High-Performance Battery at Sears .They work really good and have had no problems with them.
A pre-filter will help, but I just don't have any faith in the "gauze" type filters. Seen to many collapse and too much dirt get by.
