Saw an add on Craigslist for a used C14 K&N air filter for $55, so I checked the web to see what they go for.  Regular price is $69.95, but found them on sale at amazon.com right now for $44.81 with free shipping (if you select the "Free Super Saver Shipping" option).

It says they only have 10 left in stock (but more on the way), for what it's worth.

The best price I found for a genuine Kawasaki filter was $34.28 (w/ free shipping) at Riders Choice Racing, so for $10 more you get a reusable air filter?  Seems like a no brainer to me.

Tanks!   

So the part for the ZX-14 is what we need?

Yes, thanks! I put one in my shopping cart.

Purchased. Thanks!

Sweet!  I can let more dirt into my engine. 

This thread is NOT going to degenerate into paper vs cotton.  Start another one to debate the merits of either.

Or just buy the factory original from the second link.  Also at a good price.     No debate required. 

Well, that was fast, mine arrived today!  It was supposed to be 5 to 8 day delivery, but I ordered it on Friday, and got it on Monday!  Nice.

Thanks for the heads up. Ordered 1 & the recharge kit.  Site said there was only 1 left when I ordered mine. not that it probably matters....

I also got a good deal on the BMC air filter from Amazon.  It was $63.  I'm just sayin....

Just what I've been looking for
Thanks got mine on order
