hey peter, i did actually notic a slight difference mainly after i have been driving for a whil and the engine compartmnet is really hot, if i step on it the power is still there. its pretty cool

different sound too.
2nd question, yes they are for sale, the only problem is i know that there is not a huge demand for them, so larger companies will not produce these because its just not a wise investment to them but, i have a friend of mine that does fabricating, and he has designed this, to have minimal bends and awesome placement for maximum hp. It costed me 235.00 to have the first on made, that included 30$ to have ii polished by machine and flex hose and clamps and design air flow testing. Basically to make this short is that they are roughly going to cost 179.00 which includes polished aluminum pipe, flex hose, and hose clamps and a welded on bracket for stability. The nicest thing about this sytem i think is that first of you are no longer sucking in hot motor air, and possibly loosing hp, but you are getting ram cold air and definate power gains in every temperature and a deeper throatier sound. And if it starts to rain outside just put your fog light back in and in practically seals the filter away from any water. Oh by the way you dont have to take your fog light out in the first place.
