I am thinking about install a intake
 

But i have no idea what is the efffict?does it waste the gas or damage the car engine?

actually the intake usually helps your car get better mileage...however, you tend to step harder on the pedal after the install and waste more gas

I mean for the usually driven what helps?can you tall the advantage and disadvantage about the intake? other question my front brake has strange noise when i hit the brake.
I have just change the brake a few month ago. By the way my car is the protege 2001 ES.

Intake: louder than stcok
Hp Gain: Minimal, but still there, 2-4 whp gain
Filter is permanent only should need cleaning.

Other than that not much else to say about an intake.
If you want to read a lot more about them, and the choices, I suggest the seach button.

As for your brakes I have no idea what you mean by 'strange noise'
You will have to provide more detail.

the brake sound like the bicycle brake which without lube. It only happened at the sunny days.

is english NOT your first language ?

Even if it's not, he types better than Mr. Tooslow ... give him a break Mac -- at least we can understand what he's saying without having to read it a million times.

wasn't trying to knock him..I was legitimately asking

english is not my first language sorry for the hard undstanding. by the way what is MAC?
I am so mad to the break. Because it happend before when i get it to the mazda company they said i have to change a break so i changed but it happend again.

New Brake pads can make squeals before they are broke in, also you could be missing a spring or you might need to bleed the brakes to get air out of the lines if your brakes dont work quickly. Usually a month or a maybe 100 or more miles it will stop. Also I assume your talking about the front disc brake in particular, since I know less about my rear drum other then squeezes could be more caused by old pads on drum.

I find a OEM intake only about $100. Is this compay good? Is it a good deal?Because I only know the AEM intake. I have never know about the OEM.

OEM means that it's the factory intake that came with the car when you bought it. Don't bother spending the money ...

AEM is a good company but expensive. ($200+)
Injen is another one that makes quality stuff but also ... expensive. (also $200+)

If you want a quality intake for cheap, Simota is going to be your best and only best. You won't have much luck finding their products anywhere except on this forum. PM Kargoboy or visit this thread .

Good luck.

I am in Canada. The AEM intake will be how much? Does anyone has a good website sall this kinds of products?

Here are some prices:

AEM SHORT RAM Intakes

P-Garage $231
AEM $179
eBay $90
P5-Online $200
Corksport $192
Hopup Racing $195

Injen COLD AIR Intakes

P-Garage $239
eBay $100 (Used!)
P5-Online $239
Corksport $262
Hopup $235

K&N Typhoon COLD AIR Intakes

P-Garage $259
eBay $212
Corksport $380
Hopup $245


Now let's review these findings eh?

The lowest priced AEM sells at $90+shipping through eBay and it's a SHORT RAM!
The lowest priced Injen sells for $235 unless you'd like a used one off eBay for $100. Granted they do seem like great quality products, an aluminum pipe and some clamps aren't worth over $200 to me ...
Then we have the K&N Typhoon intakes that go for $212+shipping on eBay and yet again ... are probably not worth the money.


So at this point I hope you see that intakes for our cars are quite expensive and unless you have lots of extra money laying around and don't mind paying A LOT more just for the brand name of the product, then you'll probably search for something that's a better deal.

Now all this time I just spent looking up all these websites and prices was to show you there is a brand just as good, perhaps better on the market and is being sold by one of our local board members.

Kargoboy's SIMOTA Intakes!!!

Cold Air Intakes $85 (compared to $200+ for Injen and K&N)
Twin Charger Intakes $90

I hope you can handle it from here ...

And mac says I'm the pimp, lol.

Looks like I may have to start paying a finders' fee!
