I've been looking into air intakes and how they perform, stock vs. cold air vs. short ram. I was originally thinking that if I were to get an air intake, I would likely go with the short ram, although upon further research I keep reading that it actually loses power in the low rpm range, which is where I am most of the time considering it is my daily driver. I've also read that larger diameter intake pipes means less intake velocity, which in this regard is not as ideal as the stock setup, even if improvement can be noticed in the higher rpms. Apparently it is ideal at a certain pressure threshold or something, though my lack of knowledge in this area is why I am here.

I was hoping someone could shed some light on this - I won't be putting a turbo in it, I won't be using it to race, it's my daily driver. I just love driving it, as it is my first stick shift, and it is quite fun, and so I do intend to eventually find a reputable tuner for the engine. With these things considered, If anybody knows whether or not an aftermarket air intake is actually worth it or not for a daily driver, please feel free to let me know and hit me with the technical talk.

Thank you!

I, personally, do not think aftermarket intakes are worth much. They generally seem to get their air from inside the engine compartment where the air is hotter than ambient (and therefore at lower density), which defeats the idea of getting more air into the engine. Air velocity into the engine is NOT what is important, air pressure, or density is what is. Increased density = more oxygen molecules to combine with fuel during the burning process and if the sensors in the engine can "see" more oxygen, the computers can input more fuel to mix with it, giving you more power. A turbo increases the air pressure in the intake circuit which, since the volume is constant, increases the density.

Getting back to "velocity" in the intake, increased velocity actually DECREASES the static pressure in the air column. As the engine hits very high RPMs, it is "sucking" more and more air, increasing the velocity and decreasing the density. A turbo overcomes this by supplying more air pressure than the engine is demanding (sort of) which maintains the density at optimum levels.

Warm air is less dense than cold air. Your car engine can produce more power when it's cold out than when it's warm, but it will use more fuel then too, to maintain the same air/fuel mixture ratio.

For the kind of driving you are describing, a tune might improve your fuel economy or, give you more power at the expense of fuel economy. I don't know of any intakes that will do much for you (except maybe to add noise).

To the purists here, I know I've not said all this quite right, but I did not want to get into internal aerodynamics in detail or into stochastic processes either. It didn't seem warranted.

On the 7th gen you can actually turn the stock intake into a budget cold air intake. Just remove the bumper and cut the plastic rivets that hold the snorkel to the intake resonator. That way the engine will draw air directly from the bumper cavity through the resonator, rather than from the engine bay. It'll drop intake temps a few degrees, which should make power across the board. It will make it slightly easier to flood the engine, but unless you make a habit of driving through foot deep puddles it's probably fine.

It's worth it to the manufactures and sellers.

From what I've read here, the only advantage is that cool intake sound. I doubt if you get one HP out of any of them.

hey is there any chance u have a photo available of what the cuts you made look like? thx

No, but you just snip the two plastic rivets that connect the snorkel to the resonator.
