I think Will's air induction system works pretty well. I had it installed along with a few other unrelated items (SmartShifter and stainless brake lines) in my NSX and noticed a few noticeable improvements. Please note, I DID NOT perform a baseline dyno run or an after the fact dyno run. In fact, I have yet to even find one in Oklahoma. My impressions are STRICTLY seat of the pants.
The build quality is great - I received mine certified mail a few days after Will said he would send it. It came fully styrofoamed w/ a few Cantrell Concepts stickers and step-by-step installation instructions. The instructions included suggested use (read: don't go thru standing water). OK already, you want to know if it performs and how well. Well, yes it does. How well, as determined by my SOTP feelerometer, is again subjective, but I think fairly well. I noticed an increase in throttle response especially above 30mph. The intake noise is more pronounced but certainly tolerable and perhaps more entertaining than stock. Almost certainly, you will notice better throttle response. I was pretty surprised with that performance characteristic. In theory, I think most of the HP increase would come at speed when any ram-air (not the strictest sense of the phrase) would take affect.
Overall, I think it's worth the cost, especially compared with others, and I recommend it.
