and I came up with 11 1/4 X 8 7/8 X 1 1/2.

I went to K&N and they said it was K&N Universal Filter 33-2015.


Summitracing has it as Ford/Lincoln/Mercury: 1986-93, OEM replacement (KNN-33-2015)

$44.95

If you can backtrace it to the original Ford (Motocraft? Autolite?) part, then I might be able to find a Donaldson equivalent and avoid K&N. The GM# for the filter doesn't cross to anything

Thanks, Super! Much helpful. And you're buying a GTO after being tainted with all that Ford knowledge? :p :p :p

Hi guys,

I'm not up on air filters. Why do you want to avoid K & N products? I always thought they were good.

What is better about a Donaldson? I've never heard of them, but if there is a distinct advantage, I'd like to buy their products too.

The majority impression of got from people who can honestly quote real numbers on a couple of forums is that the K&N is a fine filter that gives you about the same HP on an LS1 as a stock paper filter, while letting more dust and dirt into you engine - how much depending on the environment you are in. Given that - I am going to stick with a stock type paper filter for a while on my car.

Supposedly, the Donaldson disposables flow better and filter better than stock. They use a synthetic medium. Problem is Donaldson is a large company geared to the lucrative industrial market. Their offerings in the automotive aftermarket are spotty. SLP have incorporated their filters into some of their stuff, and their Black Wing filter / intake is one of the best for Corvettes. It seems like a lot of companies are jumping on the performance filter bandwagon, but most of the stuff varies only in color. Donaldson seems to have a lot of research and manufacturing capability. I hope they expand their marketing efforts to make their products more accessable to enthusiasts.

I work for an industrial OEM who uses blowers, pumps, and fans in our designs. We use Donaldson on all of these applications. They have great filtration and extend the life of our equipment. They are the only paper filter style manufacturer we buy from. One of the best applications is on our Roots blower.
I've only used them once on a car. I happened to have a free sample and noticed it was the right size so I put it on the tri-power setup I used to have. Seemed to work well.
I need to start looking into this for the new goat. Though, I've never used a panel filter in our designs. Always the old round type.

Hmmm. If you have a rapport with the Donaldson reps, perhaps submitting the dimensions might come up with something. I tried crossing the Ford / Motocraft unit on their website and came up empty. Nice place to look for filters for your Allis-Chalmers though :D

What's the matter with foam air filters? Do they restrict air flow too much? It seems to me that they would filter the air a lot better.

My dad - bless his heart - still wishes that cars had oil bath air cleaners. No doubt they got rid of all the junk in the air, but you didn't get any air flow. Of course, we're talking about straight-8 engines with probably a 3,000 rpm redline...

Somebody should make an electrostatic air filter for a car.
