I realize this topic has been beaten to death and I'm no engineer (not automobiles anyway) but my thoughts are this: Martin's reference to air flow velocity vs. the shape of the air path is more commonly known as Bernoulli's principle (Also related to flight) http://www.mste.uiuc.edu/davea/aviation/bernoulliPrinciple.html so yes, changing the path air follows could increase your horsepower. That said, I cannot speak to the merits of John's airbox. I would like to point out though that if you're looking for some kind of magic bolt-on horsepower you're not going to find it with this car. It's my opinion that none of these items individually will provide you with a quantifiable increase in horsepower or performance. However, when combined as a whole the results can be impressive. Meaning if you combined an ignition upgrade with dual exhaust and a free-er flowing input the results would be worth the effort. Did I buy his K&N filter? Yes. Why? Because I noticed that my paper elements get dirty often and I get tired of waiting for a new one to come in the mail. I find it easier to wash and reinstall the K&N filter. That alone made it worth buying.
