While I was installing this intake, I had gotten to putting in the NPT piece into the intake tube (step 15 in http://www.kandn.com/instructions/69-7061_inst.pdf). The NPT piece feels like a piece of cheap plastic, and before I had turned it twice with a wrench, the piece snapped off. I was stuck with a broken NPT piece in one hand, and the other half stuck inside the intake tube.
This is probably the worst designed piece in the world. There is nothing to tell you it is twisted as far as it would go, and why wouldn't K&N just make a welded metal piece for connecting the crankcase vent hose... 
This picture was taken after I had called K&N and they told me to try to cut out the plastic with an x-acto knife. As you can see, it failed.
I got back on the phone with K&N, explained to them my situation, as well as emailed the rep a few photos. I had never dealt with K&N before and I was kind of worried because I had purchased the intake off of ebay, but to my surprise, they have excellent customer service. They sent out a whole new intake tube, as well as a new NPT piece, no questions asked. I just had to show them a few photos through an e-mail, and they overnighted my parts to me.
I just wanted to share this with everyone so if anybody plans on installing a K&N intake, they know not to tighten that NPT piece too tight and to save them from a lot of swearing and cursing. I am also curious to know if this happened to anybody else?
