Swiss Cheese Airbox
- Thread starter dichiee
- Start date
But some people would rather not waste money on a CAI when they can just do a free mod with slightly better performance and sound with a cheaper k&n filter
buying a new intake box when you decide to trade/sell is going to cost more than a CAI and the intake looks much better, sounds much better and gives you more performance. definately worth it.
You can make your own custom intake like me. (breakn)

More sound, that's it.
+1...swiss cheesing was the corny ass mod that all me and my dork friends did when we were like 16 and didnt realize how retarded it is to be asshole cheap....save up a paycheck....CAI is the way to go.

if you are going to go with K&N filter just do that...drilling holes in your airbox just gets you a stupid raspy noise and a ruined airbox....the filter change is where the performance comes from...

The gains to be had from a cold-air intake are negligable. There are much more prudent ways to spend $200+ on performance modifications. The stock airbox is efficient to beyond what your internals and unmodified transmission will tolerate.

I'm sorry my friend, but obviously you don,t know how much hp the ms3 gain from a cai. There are lots of threads in this forum about speed 3s going from 220 whp stock to 245 whp.

Im not even considering drilling holes in my airbox
Ive taped up to holes to help keep the pressure at a similar level all the way through the tubing and up to the engine.
Plus the tape helps resist some of the heat coming off the radiator.
i have a 99es so im just trying to help ms3 owners with alternatives to a true CAI

Perhaps I should have clarified-- I was referring to the protege platform specifically. I'm skeptical of a 25 whp gain from an intake alone, without supporting mods for the ms3. That sounds quite optimistic, although I'm not familiar with the mazdaspeed 3. I would, however, want to see a third-party dyno sheet for that before you'd convince me to drop two-hundred plus on a cold-air intake.

For a regular 3, I don't think it makes a difference that you can feel.
For a Speed, I think it makes a difference. I did it I was one of the first to give it a try, and most people are happy with the results. I couldn't care less about the noise from it. What I'm after is reduced pumping losses, and more efficiency in pulling air in. Simply put, the stock airbox's tiny opening is a choke on the intake. Pull that off, and open the box, and the turbo can pull more air in with less effort. It is the EXACT same principle as leaving your filter dirty vs. clean. Most of us would agree that a dirty air filter reduces efficiency and performance.. I don't care what the next person thinks about my car as long as I don't detract from its value. I challenge any of you to find fault with opening up the breathing passage of this turbo engine.
A regular 3, the difference is pretty minor because although pumping losses are again reduced, there is a limit to how much air an engine can pull in those cylinders. On a N/A engine, that limit is close to atmospheric pressure, since vacuum pulls the air in.
On a turbo car, any impedence against the turbine blades is a drop in efficiency. A turbo car can compress air into the cylinder, well above atmospheric levels. Doing this changes the rules considerably! This means a simple thing like pulling the airbox out and cutting it up will yield favorable results. Keep in mind, total peak power may not be much more, but there will be more power under the curve, because efficiency is increased. Sure an intake that has a smooth bore, and a proper mandrel bend, with a proper oversized air filter will all make a difference towards the positive. It is simply elaborating on the concept.
BTW an exhaust does the exact same thing: Better efficiency is the key for turbo cars. Normally aspirated cars need a bit of backpressure to improve low end torque. Turbo cars already have all the backpressure they'll ever need. Its called a turbo.
Now then, not to be rude or anything, but who wants to challenge this assertion?
I think that was very well written good job(yippy)

swiss cheese may be bulls*** to all you big money dudes out ther but when you got 3 kids, sometimes you have to get creative. I did it so i could hear the turbo. It works and I like it. I did this knowing that a year from now ill be getting the MS CAI. So to all you naysayers, shut up and let us enjoy this thread.
