During the 2012 GMCMI convention in Amana, IA I bought a Jeep air horn (air plenum) and hose parts from one of the vendors in attendance. I'm planning on installing it soon but have no idea what to use for the filter. I've seem most of the photos on how to do the conversion, but none of the pictures or descriptions on how to install the Jeep parts indicate what filter to use. It seems K&N filters are used, but there are hundreds of different K&N filters.
Does anyone that has done this mod have a K&N part number for the filter they used?

Before you mount the air duct to the carb, make sure you have at least a 1"
spacer under it. According to K&N, any round, tapered filter they make
will supply more air than the cfm requirements of the 455.

As an Air Filter Expert, I can warn you as to the short life your engine
will have with that type of air filter.
Yes it flows considerable amount of air at low pressure drop, but it also
lets lot of dirt flow through.
Cummins and other major engine manufactures has voided warranty on their
engine when K&N filters were used.
There are other manufactures that have more efficient filters that flow
almost as much at same pressure drop.
I know A&E has a good one. K&N recently purchased them.
I have information for you if you will contact me at my office.
We have a filter and hose kit that we have been testing for several month
on several coaches that we will be sell as a kit or by individual parts.

Hi Jim - that's really interesting - could you elaborate why this is so? I've used K&N oiled filters in a diesel truck (current owner is almost at 300K miles, same ole' filter), a couple current race cars and numerous off road cars and pre runners in the past without problems. You do have to maintain them by cleaning and oiling with the right stuff. What's the current issue?
short life your engine
will have with that type of air filter.
Yes it flows considerable amount of air at low pressure drop, but it also
lets lot of dirt flow through.

Jim,
I am using an AFE K&N type filter on my SOB. Every oil sample I send in
comes back with zero silicates present in the oil. Blackstone has
commented at least once on my excellent filter maintenance. I think where
most go wrong is in NOT following the instructions for cleaning a K&N type
filter. Any water under pressure is an absolute NO NO and will ruin the
unit. When they say to soak it in whatever soap solution you prefer, Dawn,
Simple Green etc and then gently rinse off the residue with whatever water
pressure you have coming out of the end of a garden hose, they mean just
that. Coating the filter membrane with the correct oil is the next
critical step. I used the cartridge type K&N on my Duramax diesel powered
Silvarado with the same report results from Blackstone.

Test I read showed that the K&N filters better the dirtier it gets, but flow is reduced.

On a Volvo list I'm on, a member did detailed tests to show how much
restriction there was from each part of the intake system, and with several
different filters. The filter was by no means the most restrictive part,
they were basically the same, though k&n was the best by a small margin.
Nothing at all was a clear winner :-) though there may be issues with that
setup.
On a BMW motorcycle list, they put a k bike on the dyno, and tried various
filters. No measurable difference, from k&n to stock with 50,000 miles half
blocked off with plastic wrap.
Not saying the GMC is designed to those standards, but the air filter is
not the problem.

I really didn't want to start a "Air Filters Wars" thread. I just wanted to know what size filter to get for my Jeep air filter upgrade. But this is interesting and I continue to learn as I work on my coach.
Thanks everyone for the input.

Don,
When I put my GMC on a chassis dyno, we noticed severe stumbling/leaning
out at the upper end of the rpm band. This was resolved with the addition
of a one inch tall space between the carb and the Jeep air duct.
Carburetor venturis like air to go straight past/through them. With the
low profile Jeep air duct, the air was introduced into the carb at a severe
angle. The space allowed the air to "straighten out". The space used was
from a 80's vintage Cad with TBI. Holley also makes a plastic one that
fits most carburetors. Anyway, after the spacer was installed, the engine
pulled hard throughout the entire rpm band, no stumbling and leaning out.

Thanks Steve, I didn't think of that, makes much more sense that just volume of air.
