Challenger Reusable Oil Filter

[panther1400]

What are the ups and downs of theses filters?  Dont know if it makes a difference what engine it is going on I am looking at one for a tsio-360.

I think he meant challenger oil filter.   I switched to the Donaldson air filter and our wot ff increased 1 gph.  Presumably the higher airflow.

Yes we switched out the brackett.  The brackett was 15$ and lasts a year, the Donaldson lasts 3 years or 500 hours whichever comes first. It's 100$.  So 50$-60$ extra over 3 years.

The Donaldson filter flows more air than a Brackett but filters better that both the Brackett and the Challenger.  They are made of synthetic paper now, so they go a little longer.  P/N is 13-0234.  You also need two AN3-25A bolt and AN960-10 washers.  The Brackett ones I had were too short  I'd go a little longer and use an AN3- 27A bolt.    It has no housing, it is a metal box with the filter inside it. Its also in the parts catalog, so PMA replacement.

I don't know.  The airplane picked up around 5 knots but that was also done at the same time as the 25 degrees timing.  I would guess, it helps some, 2-5%.

Sorry to hijack your thread.  Here is some discussion on the Challenger oil flter.  I am interested in it, we did 4 oil changes this year,
