Intake Question
 

A couple days ago, I saw someone posted 2 photos here about 2 different types of intake for P5.
The first one have the cone shape filter extend down under the hood.
The second one have the cone shape filer high up on top placing inside the hood where the original filter box used to be.
Does anyone know what is the 2nd one call?
Where can I buy it?

I am driving a Auto Tranny P5.
I want to get the 2nd one cause I worry the first one might get my P5 into trouble when driving in heavy snow or lightly flooding condition.

Go for the first one, more than likely the Injen Cold Air Intake - seriously. Honestly, you would have to submerge your car a few feet deep in water for there to be any chance of damage. And by that point you've already waterlogged your vehicle so it would not matter what kind of intake you bought :).

If you are really that worried, buy the splash guard or bypass valve that can be attached to the intake. Water is not going to get up there even in the condtions you described, and either of these two additions to the intake would give you that piece of mind.

Thanks.
Can you explain more alittle bit about the splash guard and the bypass valve?
Or can you give me a link that shows how they look or how they work?


How much does the whole system usually cost?

Injen Cold Air Intake: $250
Bypass Valve: $41
Splash Guard: $49

I personally (before the turbo :) ) used the splash guard as I thought the bypass valve was not necessary. The splash guard is a metal shield that covers the side of the air filter most likely to take in any water. This link above though will show you in greater picture detail how this all works. Let me know what you think!

In one of those photos (the one at far right), there is another smaller red tube connecting to the engine. What is that tube doing there?


How long did it take you to install the intake for you car?

I believe the hose you are referring to is part of the PCV system. Nothing major. The installation took me a little over an hour. DO NOT follow the instructions given with the intake - they tell you pull the front bumper off which is a collossal waste of time. Follow the instructions on Protege5Online.com

Thanks for the tips!
Now I need to find a place that have a good deal on it.

Someone in this forum also mention the AEM intake.
What do you think about that one?

The AEM is a "short ram" intake that doesn't go down into the bumper well like the Injen. I know someone with an AEM on his car (not a Mazda) and I prefer the sound and response from the Injen, although in all honesty the performance difference is negligible at best. The Injen combined with an exhaust gives the engine a nice throaty growl on the acceleration and sounds like it is sucking in air when you shift or accelerate.

So you buy the exhaust seperately? Or it's a package included when you buy the Injen?

Another question,
Can the cone shape air filter be washed by water? Do I need to buy a new one?
Or do I have to wash it with special detergent instead of water?

no, the exhaust does not come with the cold air intake. A catback exhaust will run you about $400 to $500 depending on the vendor you choose - Racing Beat, Bosal, HKS. I chose Racing Beat because of thier history with Mazda tuning and the sound. You can also have a muffler shop like Midas make you a custom system with mandrel pipe and a sportier muffler - probably cheaper than buying one of the aforementioned systems. Lots of options to go with, all a matter of choice.

K&N makes a special cleaner that you can pick up at virtually any reputable auto parts store.

By the way, be sure to join the "other" Protege forum at www.msprotege.com :). Lots of good people over there too.

Thanks for the tip!

About the exhaust, do you have to have the exhaust to work with the intake system to get the extra horsepower? Or it's just an extra touch?
Can the stock exhaust suppout the output after the installation of the intake?

the stock exhaust can handle the extra five or so horses that the intake would give you, its not that powerful! the problem with the stock exhaust is that it is restrictive compared to an aftermarket exhaust. you will have less back pressure and better "breathing" for the engine with an aftermarket system. for example, the pipe on most aftermarket exhausts is 2.25 or more inches with a straight through or straighter muffler compared to a thinner pipe and snaky muffler on the stock system - exhaust gases will escape quicker from an after market system. thus, your gains combined from both will give you more horsepower. Racing Beat claims an added five wheel horsepower from just thier exhaust which I think is a little high. I think that an exhaust and intake together will give you between 8 and 12 horsepower tops.

When you mean aftermarket exhaust system, do you mean replacing the whole exhaust pipe or just the ending section of the muffer?
