panther1400 Posted December 1, 2011 Report Posted December 1, 2011 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.
jetdriven Posted December 1, 2011 Report Posted December 1, 2011 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.
jetdriven Posted December 1, 2011 Report Posted December 1, 2011 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.
jetdriven Posted December 1, 2011 Report Posted December 1, 2011 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.

jetdriven Posted December 2, 2011 Report Posted December 2, 2011 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%.
jetdriven Posted December 2, 2011 Report Posted December 2, 2011 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, http://www.piperowner.org/forums/topic.html?id=86686
