i was just makin sure its ok to take out the air box in your car to make an intake by using the stock piping and just put a filter on it to get more direct air flow. if anyone knows that would be a big help. thanks
It won't be as good as the intake you already have, I'm sure, unless your car is very old. Since the 1980s car manufacturers have spent considerable effort on air intakes and virtually all cars made since 1990 have better intakes than you could buy for under about $1000. They spent millions researching how to get best power and economy out of the engine. you can't compete with that. If you are drawing air from the engine compartment you are going back to the hot air intakes of the bad old days (1960s and 1970s), when cold air intakes like the ones on modern cars were useful aftermarket upgrades. I no longer try to answer questions by the people who ask what to do about the loss of power, loss of fuel economy, check engine lights on, failure to pass emissions. after replacing their properly engineered intake with something that was designed to sell, not to work.
Don't worry about the air intake on my car. You should be more fully aware how you're factory installed cold air intake works. You're going to a lot of trouble for nothing but big trouble! The stock cold air box, and air entry piping under the left front fender has a built in water-drain trap should moisture enter the intake source. You'll get less horsepower with hot under-hood air because there's less oxygen in it. All you have to do is to drop in a KN air cleaner in the present cold air box if you think you want more efficient air-flow.
It is not just like that. I was about to install something alike and these are my thoughts. I wanted to direct frontally oncoming air into the intake so that the faster I drive the more air pressure would be created - there would be more mass of air entering the intake (something like air scoop, but with funnel and other stuff). However, there are few problems.one of them is water, for example, rain that may be forced through filter and further toward cylinder. Air box is designed so that the air filter is protected of some greater amounts of water reaching it.on the other hand it naturally increases resistance to air flow so the engine loses some additional power to suck air through the box. When it's dry outside air box may be excluded in order to gain some benefits, but when it's wet/raining it should be activated to protect the engine. Also, air inside the engine compartment is warm/hot so it is of less density and less mass of air is entering the intake system and finally the cylinder - decreased power. You need cold air for your engine because it is denser than hot air which is in the upper side of the engine compartment, so you need to install air filter at the bottom of the engine compartment - again, the problem is water because if the filter is positioned low water can reach it much easier. Also you need to convey the air from dislocated filter by some additional pipes which again increase air flow resistance. As you can see you need some engineering before redesigning original intake system.it is not just let's do it job.
