[QUOTE]A BIGGG waste of time on a N/A.



why would this be a waste of time?? all cars like cool air and perform better with it.

 

If you do it, go all the way and duct in some fresh air

dont just go sticking some open element air cleaner in the

engine bay and think it works better then the way

Mazda did it which was to draw the air above the radiator support.

Plenty of cool air there, it keeps your radiator cool doesnt it?



Until someone comes up with some dyno testing of a brand new

air cleaner versus a "cold air" set up, I say they are a waste of time.

 

good point, good illustration. still, an insulated cool air box for $26 that isolates engine air from intake air shouldn't hurt, and it will look pretty cool when you pop the hood. personally, i'd wrap mine in heat sheild insulation.



and if you want a head light intake, go RX7.com, they have them for $144, and they look better than mariah

 

although those headlight intakes seem like they might actually suck air away from the intake due to the negative pressure differential...

 

thanks for your input rob x7,

I will give it some more thought before I do it.

 

let me know if I have this right:



so, it's best to leave the filter under the hood, and not in front of the radiator, but it's good to duct air from somewhere else. The best place to duct air from would be the in-front-of-the-radiator area. What about down by the brake duct like the guy on the other forum? It looks like either way a hole will have to be cut to route piping, right? So is it better to cut a hole below the filter area, or in the radiator support? Or is it better to just build a box, ducting air from the stock cold air intake?



For using the stock intake setup, should I remove the black plastic that's above the horns?

 

talking about this topic. I have a CorkSport Headlight duct that i purchased a long time ago. Ive never put it on. I have the sandpaper and the paint but havnt got a chance to do it. I am also trying to make a cold airbox. Il post pictures later when i get home(in school). I have one peice made. I just have to make the peice by the upper radiator hose and the bottom peice (which will be harder due to the s4 big mass air sensor and the oval shape of the K&N intake.............and im not mechanic or am good with my hands...but i gues ill show you what i got so far so ya can point and laugh at my car lol





jason r..

 

I saw your pic in another thread. Looks like you're doing good so far, as far as I can tell.

 

lol yeah i hope so. ANd yeah i got stickers on my car there MAZDASPEED they give me 100 hp man lol. Here is the latest pic of my engine bay

 

if you don't care how it looks get a cowl induction hood... its airflow is incredible.



thats your best bet for speed, but its expensive, and ugly
