yeah i seen that thingy to but i ripped out my stock intake like a week after i got my del sol and put a AEM cold air intake it's one of the best things i've done to that car but to put it in you got to take out a lot of stuff that doesn't really do anything but hey ....what ever......my advise would be to go with a aem cold intake you'll feel the differance you can pick them up off ebay i got mine for like 70 buck total so i'd say that a come up from 200 something LOL

 

the intake is just a tube so as long ans it stays on and you got a good filter your good. there some cheap ones on ebay for less than 50. as long as you get a K&N or something on there thats just a good. wut eva filter it comes with is probably better performance then stock anyway.
