Is the factory airfilter can be cleaned or I have to change it? And if I buy a K&N style filter, do I need a fuel management system or I can leave everything stock. I have monster ovals slip-ons.

 

You can wash the stock filter.

 

You can probably knock most of the loose dust out of the filter or blow it with air but I just replaced the filter before I got my SE AC from FuelMoto. I don't think it's washable. Can't tell you about the fuel manager.

 

I'm pretty sure the stock air filter is not a washable element. Not 100% sure though, I've never had one on long enough to get dirty enough to change. As far as upgrading just the filter with a K&N element, you shouldn't have to do a FMS, you're just swapping filters. If you went to a full Stage 1 intake, or another style intake, then you would need a tune.

 

If your filter is a paper element it's absolutely not washable. Don't cheap out at the cost of an engine. Get a new filter.

 

The filter is washable once, you just can't use it as an airfilter after that though. In a bind you could carefully knock the dust out of it and carefully blow through it with a compressor.

 

Yep its washable. See owners manual for instructions.

 

Hey no chit, Diablo is right on this one. This statement is taken from my '06 owners manual:

"The paper/wire mesh air filter element should be washed in luke warm water with a mild detergent. Allow the filter to either air dry or blow dry it, from the inside, with low pressure air"

 

When it comes to paper filters, your engine not mine for 25 bucks.

 

Buy a new filter. Motor needs all the air it can get. A K&N filter is a better idea. Double the cost but a few more pony's.
