I have round air filter 29244-08(Harley), but parts diagram for my bike shows different, kind of oval filter.
I cannot find my filter here:

I would install original but filter holder is different

This is the OEM Replacement and fits the "football"
The police bike may be different stock or it may be an aftermarket.

 

The Screamin' Eagle air cleaners use round filters, most likely what you have on your bike. The K&N air filter for your set up is part number HD-0800 if I am not mistaken...

 

Yeah my screamin eagle filter is round and uses the stock football cover. Good chance that's what you got.

 

Ok I'll bite...
So if you have the round filter which is high flow then you must have either a tuner or a download. What kind of mufflers did you have before the flex pipe specials? And why do you want to change it anyway? Save your money for a set of slip ons....

And for those who are keeping score..I nailed it on who the OP was

 

Bike is from police auction, transmission was cracked, I installed 08 transmission. It has different oil pan, that is why I cannot install original exhaust system until I install 13 oil pan. I don't think police fleet mechanics were upgrading the bike parts. Round filter most likely came from factory.
I bought a filter from ebay for $24 shipped.
Mine was damaged.

 

I have a round air cleaner.

 

Now I understand the whole pillow for a seat and flex pipe for mufflers. I probably would have been anxious to try out a new to me bike asap as well.

So the actual trans housing was cracked? Was it driveable? I wonder what happened? Must have got it for a good price like that.

 

I paid $2900, lots of money! +Transmission $550 shipped. Saddle bags with hardware $200.
I am probably close to $5000 already.
Oil pan was empty, case was cracked. I didn't try to start engine until installed transmission.
