Has anyone tried the NOLOGY Hotwires? http://www.nology.com/hot.html
I just found out about them last week from a guy I met that owns a 4X4 MOD shop. He has them on his 8 CYL Jeep Grand Cherokee along with a K&N FIPK. Said they increased his horsepower and gas mileage considerably. (not sure how much he just installed them) For the X they run $249.95. Before I spend the money I am curious how much difference it will make on my 3.3L. Is a new product? I don't beleive it has been covered on any forums yet? (not that search showed)
Their link makes them sound like they are worth the money, and is full of great techincal data to support how great they are(of course). I would rather just hear it from an Xterra owner.
