Hi Denis, You could mention that airmaze filters might be available thru
B&B Aircraft Supplies in Kansas 913-884-5930. I bought a few from
Dan a couple years ago . He had both the small and the larger ones for
the 145 heat box as I recall. -- Mark
AMAZIN AIR FILTER... (100400)

A-Mazing... Here is my take on air filters. The original Air-Maze filters
are at least 60 year old technology. They work fine and there is no reason
not to use them, but there has been some advancement in filter media in
the past 60 years. While the Bracket filters are modern technology, they
are restrictive. If you want REALLY clean air (which you would never get
with a NEW Air-Maze anyway), then maybe the Bracket is for you. If you
talk to Mike Williams he will tell you that you lose 1" manifold
pressure at full throttle with the Bracket, so you decide. I prefer the
Cessna paper filters. I look at it this way... Iffn you are gonna use
a C-170 carb air box, you might as well use the proper filter for it since
neither are approved on the Swift anyhow (without a field approval). They
do require adherence to AD 84-26-02, which requires a 100 hour inspection
and a 500 hour replacement. 500 hours is about the limit for any paper
filter anyhow, so that ain't bad! They are not restrictive and they are
a good compromise when it comes to clean air. They come new with the required
gaskets. The part number for the C-170 filter is P10-7172 (formerly C294510-301).
The last one I bought was in 1997, and the price of $52 sticks in my mind.
Good luck... Steve W

I believe if you check the filter element you get from Cessna for the
170 it will not be paper. It is a flocked element based on a wire screen
support. It is also washable (paper is not washable). AD 84-26-02 ONLY
applies to PAPER filters. -- Wes Knettle
AIR FILTERS...(020401)
From: Bud England <Dalswift1@aol.com>
Jim: Seems that I remember you writing the definitive article on air filters
etc. for the 145. About the different filters, heat boxes, ram air and
so forth. Do you or Denis still have a copy? I'll print it and save it
this time.
Bud
The heat box to use is a p/n 530852 which was used on the Cessna 170's
and early 172's. The original air filter was a 627357 I believe, but later
on Cessna came out with a paper filter that was much superior. The paper
filter does have an AD note requiring it to be replaced every 500 hours,
which is reasonable. The most popular filter these days is a Brackett.
The Brackett does the best job of filtering air, but I don't like it!
The foam element will present a slight loss of manifold pressure and I
don't like anything that costs power!Also see Steve Roth's note on Yahoo

AIR FILTER FUN... (APRIL 04)
Texas Swifter Ed Lloyd <swift3856k@austin.rr.com> tells us that
Axis Aero http://www.axisaero.com/
offers air filter products applicable to the Swift. Their latest item
is an induction air filter for the Continental IO-360 engine. Ed says...
"I am running a K&N induction filter on my engine and I really
like it." For more info visit the Axis Aero site or contact Ed for
a first hand testimonial.
STEVE SAYS WE CAN DO BETTER
WITH K&N FILTERS... (AUG 04)
From: Steve Roth <Swift97B@aol.com>
Subject: Challenger Air Filters
I had a hard time getting Airmaze air filters. The new K&N Challenger
filters are better than the Airmaze and look less restrictive, especially
less restrictive than the Brackett filters. They are reusable, FAA/PMA
and a direct replacement for the common filters. K&N filters used
on just about everything now. I got one for my 145HP Swift. Cost about
$80.00 then there is one time cost for cleaner and grease ($10.00 each).
Customer Don Shields talks about his Cessna 172 Challenger air filter:
"I just had to test my Brackett filter against the Challenger filter
and found that I climb about 100 feet per minute faster and burn less
gas. My total fuel burn with the Brackett was 6.8 gallons per hour. The
Challenger filter dropped that to 6.5 gallons per hour. I fly about 150
hours a year and K&N will save me 45 gallons of gas." Thought
you might want to know. Streve Roth (http://www.challengeraviation.com/)
Steve,
I guess I really don't like Brackett Air Filters for several reasons.
One, they are restrictive Two, it says in the Instructions for Continuous
Airworthiness for the STC that the Element MUST be changed annually. When
I do an Annual, the typical owner says "but I only flew ___ number
hours last year". Even if you flew ONE hour the Element MUST still
be changed! Three, many Brackett Air Filters are installed without a 337.
They are a Major Alteration and require a 337. I have made out dozens
of 337 forms for Bracketts (and charged the owners) I won't relicense
the airplane otherwise. -- Jim

AIRFILTERS QUESTIONS...(AUG 04)
From: Denny Moore <roanval@mounet.com>
Subject: Can you help
I am researching to beat the band to find where I read about a Swift air
filter. It must have been in your news letter. I have saved in a file
every news letter and cannot find this info anywhere?? Someone wrote a
in about using a K & N air with an adapter on their 210 Swift. Do
you remember such an article? Denny Moore
Yo Denny........here's the web address for K&N www.knfilters.com When
the site comes up click on UNIVERSAL and then on 'round tapered'. I chose
the round tapered, 20 degree angled filter for my application due to cowl
clearance. With the 20 degree offset angle it gives you a lot of lattitude
in positioning the filter for cowl clearance. The part # of the filter
I use is RX-3800. I got one of their "cleaning and oiling kits"
and intend to do that on annual each year. Cheers.......Ed Lloyd swift3856k@austin.rr.com
