I got my K&N filter for just over half price as old stock. That was a real bargain and I'm so glad I had that good luck or I'd never have bought one. I had fitted a pod air filter which was better than stock and increased the top end power but caused stalling at low revs, also they kept falling off so I re-fitted the air box (Living Hell!) and popped one of these in. The engine runs almost as well with this as it did with the pod and is much more efficient at idle, no more dying at junctions which is a big problem with the NX650. This often happened with the original lower price filter elements and was worse with the pod (I didn't re-jet, life's too short). The K&N filter IS expensive but it's far better, in my experience, than the cheapos and, being cotton, is re-useable (wash, dry, re-oil and off you go). I would certainly recommend it.Read full review

Perfect K&N quality. Smoother sound of bike and surely more torque. Strongly recommended product.

Without a doubt the best oil and air filters you can buy. Perfect fit and although initially expensive saves money in the long run as you DONT throw away these filters. Wash and use again.
