K&N Airfilter

tjlawson86 · Mar 26, 2009

I was surfing the web bored... and I ran across this K&N airfilter thats made like the stock filter instead of the twin filter Ive seen before go check it out the part# is KA-2508 Im really thinking about getting this one cause I think it would be alot easier then the other one.

It is alot quicker.Just pull the OEM out and insert the 2508 in.Be causious about the direction.The 2508 is tappered and will fit only with the right side in.

Did you notice any change in the performance?

how often does the air filter needs to be replaced?

Racer X · Mar 26, 2009

It wont help or hurt your performance . You can clean it yourself and save . Check it with every oil change.

cool. nice pic btw

It should help the bike breath better and the sound on the air intake should be cool.... Just wondering if it would lean out the engine further if the bike's carbs are not shimmed or jetted.. Eric, how much does it cost? I am thinking of buying one and installing it after I have jetted my carbs... Cheers

Replacing?No no.This will be the last air filter you ever need on your current bike.
But to use it you also need.

how long will the stock air filter last, i just cleaned mine, re oiled it, and it looks as good as new yet. I put 5000 miles on this filter but looks new now that its clean.

I just got 3k on mine.. I will look into the air filter see how bad it is. I did the synthetic oil on the engine and the gears are like butter... smooth.. BIG difference.

xthrice89 · Mar 28, 2009

Im not used to synthetics. I got a 90 dodge ram that i put conventional oil in but what would you recomend for the bike. What type of sythetic oild do you use?

spooph · Mar 28, 2009

I have 13,000 miles on my air filter, and I still wash and lube it every 1,500 miles, when I do my oil changes. All the long time mechanics and racers I speak with say to just use dino juice and change it often. If you don't want to change it as often, use synthetic, but for some reason, in my mind, knowing how I ride this thing, I'd rather change the dino juice every 1,500 and get the opportunity to peak at it, and check the magnetic oil plug for shavings, etc.

I used Mobil synthetic 4 stroke motorcycle oil 10w40

xthrice89 · Mar 28, 2009

Thanks, I'll be using that for my next change. Does the synthetic eliminate that minor clunking of the shifter in the lower gears?

hi-tech · Mar 28, 2009

I notice a great deal of difference on the gears and on the engine

So I cant use the airfilter without the cleaning kit?

Travisty · Mar 29, 2009

Of course you can. He's just saying that you'll never have to replace the K&N. Just clean it with the K&N kit and it'll be like new.

Travisty is right.Clean and reoil it and it'll be like new.But to clean and reoil it you need the K&N cleaning kit.A kit will last many cleanings.K&N will get dirty and cloggedup like all airfilters do.

i changed to the k&n drop-in filter. at idle it sounds the same, but going through the rev range, the note is different. not louder... but it does sound better. also, it runs smoother. i am happy with it.

previous to that, i had put in two washers per side and pulled the snorkel.

xthrice89 · Mar 30, 2009

What exactly is the snorkel? I have been wondering for a long time but always forgot to ask.
