Let's settle this (air intake) once and for all.

Now, I have just spent 3 + hours reviewing the DML archives trying to gather data about the differing air intake setups and their merits, and I am still confused!

I will try to summarize things a bit here, and ask for the mechanics here to enlighten my Puerto Rican arse.

FIPK:   Filtercharger Injection Performance Kits  eliminate both the air box and the restriction. FIPKs vary in design because they are application specific meaning each kit is engineered to fit a particular make, model and year of vehicle.
FIPKs utilize a 360 degree filter design which provides increased surface area to promote air flow. Port injected engines are outfitted with a conical shaped filter while centralized fuel injection systems are sized with an open element cleaner which again, makes available all of the air the engine can physically use.  (  huh?? )           As I understand it, the benefits of open filter element are:  less restriction and much, much cheaper. As far as cool air, many run a home-made hose up to it. Others, modify their hoods. A drawback for many is that it can be pretty loud. And, someone stated:
"That reminds me, I found out after driving once off road with the K&N that
you're supposed to use a pre filter when off road. The mechanic told me he
cleaned some gunk out of the throttle body, hopefully I didn't cause too
much damage. If you have a K&N ( open element) and plan on driving off the pavement, make
sure you do something with it first."

Typically  either the 10 or 14 incher is used.  The 14 is a tight fit, but apparently for '99 on, it will fit.

"   you can use the 14" with a 3" filter. I have just put one on my '98 yesterday.
It is a very TIGHT fit, but you can do it without damage to the hood.
It's true though that with the stock hood you'd be better off with a
2-3/4" filter. The 3" filter requires a carriage bolt that rubs against
the hood's insulation liner. It rubs through the 1st layer but never
gets to the metal...."

But does SIZE REALLY MATTER?

 The Mandrel web page, which is now no longer running, stated that for our 5.2 V8, the 10 " was more than enough.
    "  With the calcs, you'll find that a 10 x 3 paper air cleaner provides almost twice the required area for the V8. The
         oiled gauze provides even more. "                              opinions?
 

For installation, I came across this:
  " I don't know if you've looked yet, but this bracket covers up about 1/4 of each throttle bore (not good). This bracket is where the
offset comes from in the stock configuration. "   and on and on about removing this and using the homemade S bolt.   Is this bracket removed for the FABM set up?
 
 

But:
                          "The shape of the filter is less important if the application calls for a remote mounted filter, which
                            includes many late model fuel injected models. Typically these vehicles will use a flat panel filter or a
                            conical or cylindrical shaped filter with a rubber mounting flange designed to be mounted on the end
                            of the inlet hose. "

FABM
      Fresh Air By Meldrum (K&N FIPK Clone)  Tony DeAnda has a home made set up, that is found at http://www.dakattack.com . There are many others similar to this, all pretty much follow the path of the stock set up.
  benefits seem to be:  quieter, better filtration for off road use, and gathers cooler air, which is denser.
 
 
 

questions:
 

Why is the FABM used when it costs 100 more?
Correct me regarding the benefits and drawbacks of each.
Does cool air make THAT much of a difference?  enough to get the Tony set up, or, enough to just bother with removing the radiator rubber 'curtains' and running some hose to the open element filter?
Does one make you lose low end vs. the other?
 

thanks.
