I'm just starting to learn more about cars and what not..so if you don't want to be reading about nooby things and question, it's best you go back now :\

My friend was suggesting that I get intake? what does this mean? and what does it do? Please provide prices and brands too! I'd like to do some research! PLease and thank you!! :D

I would strongly suggest you google "car intake" or similar and find out what it do. ;)

As for what is popular for the Coupe, AEM makes a kit that my friend has.

Now do I think it's worth it? For $200+ what you really get is a difference in sound, with an unnoticeable gain in power, and bragging rights. I happen believe that depending on the vehicle and type of intake (cold air vs. short ram air, or "warm air" intake), you may even lose power, but that's a whole different story. It's your money. :)

I did google it :X lol but all i read is that it connects to the part where the fuel goes in and that the intake and fuel injection go to the part where is compresses it?? lol confused :( anyway. I just read that getting an intake creates cooler air for your engine and that it's better for your engine?? haha not sure if that's true or not :\ so as you can see...i'm still pretty lost and confused ahaha. But $200+ ?? wow :\ I think my engines okay the way it is now -.- haha

An air intake is already there on a car. The engine's factory air filter cleans the air as in enters into the engine , and you are usually reminded by the stealership to replace it every 15,000 miles.

A factory engine air intake is often somewhat restrictive for high performance, high rpm work, due to the diameter of the piping, the air filter setup itself, and the various baffles etc., designed to silence some of the engine sound that is heard from that part (not exhaust sound, but some mechanical and other air related sounds as it enters the engine).

An aftermarket intake as I see in this K&N ad banner below my post as I type, will have a larger cone shaped reusable/washable filter. It allows more air to pass through, at the slight chance of also allowing a little more dust into the engine (nothing a regular oil change won't take care of). The piping is also enlarged by a small amount, to allow the air to travel more easily. There are also no real sharp turns or other restrictive design issues with an after market air intake, so airflow is theoretically increased, and as you may know, more air = more power....usually.

The "colder" air (relatively speaking....it's still over 90*F as it enters an engine or hotter) is more dense, so more molecules are present, which means more "stuff" to burn (oxygen primarily). The name "cold air intake" usually means, the kit is designed to suck in air from a lower point in the car (where cooler air is better available away from engine heat). Usually the cone will sit facing the wheel fender well, or toward the front bumper. A "warm air" or "short ram" intake is, as it sounds, a shorter, simpler setup. The piping may only go on to extend around the top of the engine bay still, but because it still uses a cone/aftermarket filter, and the piping is enlarged, you potentially still gain some power.

Now, why do I think that the stock intake in our Coupes is probably still better? Because the stock intake is designed to suck cooler air in from the grill/hood seam. The piping is plastic (which is more resistant to the engine heat) so the air is possibly better insulated from the heat around the engine bay, as it enters the engine. MOST, not all, aftermarket intakes use metal tubing which quickly heats up to the ambient temperature of the steaming hot engine. Also the "short ram" intake, which BTW, is the only type of intake made for our car (due to car's engine bay design issues) sucks in air from around the engine bay due to it's placement....which as you guessed it, is a nice and hot 100*F or maybe a few dozen degrees hotter, defeating the purpose of the "cooler" air theory. However, one can argue that the more free flowing plumbing of the intake kit would still be better overall compared to the stock, somewhat restrictive, air intake.

Ok so all that aside, most intake kits will give your car that growl (from the engine bay, not the exhaust, technically), so it's worth it for that if you really want that.

And yes $200 seems like a lot, which to me is, when looking at the "bang for your buck-meter" but there are far worse offenders, such as cat-back or just mufflers, which can range into the $200-$1000 range for a handful of horsepower (and mostly sound). ;)

OH WOW! Thanks for that! How do you know how much about cars? I don't really go for the sound. I've really started getting into learning about maintaing my car. My first accomplished goal is learning to wash and detail the exterior ;) lol i know it's lame..but I'm still learning to use the claybody and the wax. I'm scared ima wax it wrong and mess it up :\ I've learned how to change the oil but as for other things that pertain to the engine and all that is still a mystery to me. But I suppose baby steps is what I need to be taking cuz i don't wanna rush through everything, you know? :)

Yah I understand what you mean.

And I don't know that much about cars, though at age 11 I did learn how engines work, basic theory that is. But when it comes to real practical knowledge I am no better off, still learning.

The waxing, you can't really do wrong, all you'll do is make is really shiny and, waxy? It's not lame to wash and detail your car, since most people don't seem to do that themselves, and from those that do, often seem do it somewhat wrong (like using a rough bristled brush to was dirt off a car's painted area....yah say hello to swirl marks and surface scratches!). Doing your own oil changes is a good step forward. I don't/can't even do that. Kinda' afraid to really mess with that stuff.

Haha yeah exactly why i'm scared! (with the waxing and stuff) But yeah, still starting out to wash, wax, and now i'm reading something about polish? Not too sure if that comes before or after the wax now. So now I'm jsut reading up on products. Another person directed me to a pretty cool site with all these products! And i'm getting so amped to start using them all! hahahaha
