Whats this I saw on Ebay?
 

Ok, I am a newb to the sports car world and the forum, so go easy on me if this is incredibly stupid. But whats the deal with this?:

EBAY HP Kit

Whats the catch with this thing?

THERE IS NO CATCH. IT WILL AWESOMELY IMPROVE UR HPEES.

Honestly, I can't even tell what it is. But, think of it this way, if there were a 20 dollar method to improve the power on your car by 15-20HP, why doesn't Mazda include it standard?

I saw this exact kit being sold on eBay for a 1977 Jeep..., which don't have chips in them...

LOL, like I said it was a newb question. Thanks for goin easy on me.
