I installed hte system last week and had no problems at all. All you need to do is cut a small 45 degree chamfer on the insidede of the end of the hose that goes on the valve cover with an X-acto knife and hit it with a little WD40. Mine went right on. The only thing I noticed was that the passenger side hose was way too long an after cutting it to a length that kept it from kinking, I did the same mod to the valve cover end and it went right on.

When I first got my Z last month I immediately replaced the factory filters with K&Ns, as I have been doing on my vehicles for the last 20 years or so and kept the stock airboxes. I noticed a mild gain, and then bought the Invidia exhaust, but still nothing exciting. I then decided to take the plunge and get the Typhoon system, which I got for a little over 300 bucks on eBay, and the difference in perofrmance is astounding. I live at close to 6000 feet, so perhaps the extra airflow accounted for the noticeable increase in performance, but having read all of the threads about how only the Stillen tubes will give a real performance gain and that the Typhoon is little, if any better than the stock airbox with K&Ns or other performance filters, that definitely has not been my experience. Definitely worth the investment.
