no not at all... Cold air intakes are really not much of a power mod on NA cars. Get a blower and its a different story. Anyhow, They do add a little bit if you get a good one, i suggest a densecharger.
i think they recently changed their name to demolet-----> demolet.com.
but Stay away from any of the metal kits if you want any actual gain, not just bling. also, what are your other mods? Because you can probably get alot more bang for your buck modwise. gears or a short throw are always a good start. 410s are the way to go if you plan on staying NA, 373s maybe for a FI car.
