What airfilter do I need?

[J0nathan225]

Looking for some help getting the right airfilter for my '64 E with ARI cowl mod. The airfilter slot is larger than the Donaldson: pn p107172 which is supposed to fit this year Mooney. Maybe I need the J filter?

Jon, before I got the SabreCowl I had a Challenger. Reusable, 100 hour service involves cleaning, re-oiling. Air flow gain vs. original.

I think I still have it if you’re interested. My new cowl uses the same technology but a different size.

That is a stock E air filter.

It looks like you have a Bracket filter. The new element is:

I don’t see a Donaldson filter for the E and F

The only thing a high flow air filter will do for you is give you a tiny power increase on takeoff. In cruise just open the ram air and the air filter doesn’t matter.

What Turbomaster said. You  need a Bracket element

But it's an oily mess. Have there been no improvements over this? 

Thanks for the replies. The good news is the bracket is much cheaper, I guess.

Bob, 

I'm not opposed to, how old/hours on it? I already bought the wrong Donaldson so I may just run up to Falcon field and swap it out for the challenger. Is the challenger a direct replacement for the bracket style? 

 

For ram air, I usually don't cruise with it open for the concern of even at 5-8k there may be STUFF in the air?  I could just me making this up in my head, should I run Ram open unless going through cloud/rain?

If Jon doesn't take you up on the offer, I will. I can have Ron clean and install it at annual.

Jon, it’s 7 years old, I got it from PFS when I swapped to their exhaust. I’ll take pics tomorrow.

 

You might discuss with Lynn for details about Bracket.

 

I no longer have ram air with new cowl but it was worth 1.1” MAP before and I used it whenever I got too high to get the HP I wanted. I would not be concerned about dust unless there’s something like a forest fire going on. I would close it if flying through clouds.

 

KP, I’d be glad to pass it on to you, I’ve got my money’s worth.

The original filter was made by Air Maze, I have never seen one on E or F model.  The Brackett version may be a bit messy, but it’s better than the K&N which is not the most robust design.  They seal poorly against the cowl opening and quickly lose their cotton fibres, allowing dirt into the engine.

If you haven't decided, I would steer away from Challenger filter (AKA K&N).  I had them on M20E and the engine monitor did not register *ANY* increase in manifold pressure comparing to the Mooney stock filter.  It's the worse $250 I have ever spend.

I bought the Challenger filter for my C model back when they first got approved and were still a reasonable price. I was skeptical on the performance claims but for my plane I did see a 1” increase in manifold pressure at altitude. In fact I was seeing the same numbers as an F model with the ram air door open. 
I am happy with mine and have had no issues but at the current prices I would go with the Donaldson filters over the Challenger or the Brackett.
