What does cold air intake do

Because the cold air intake affects the engine, a dirty, clogged or failing cold air intake will decrease the performance of the vehicle as well as its fuel economy. Through years of usage, the filter in the cold air intake will eventually get clogged since it continuously sucks air in.

Generally, aftermarket cold air intakes their filters have to be cleaned every 30, to 40, mile and not necessarily replaced thanks to its reusable air filters which is unlike factory air intake systems that come with paper air filters that need replacement every 15, miles. To make sure you get all the benefits of a cold air intake system you need to make sure they are in good condition. Here are things you should do to keep your cold intake system perform in its optimum level:.

In theory, cold air and getting more air sound really good but it does not really make a difference unless it is put into application. While the actual increase in horsepower and fuel economy may differ from one vehicle to another, one thing is certain—it can definitely improve the performance of your car. With the cold intake system alone you will notice a boost in power when the throttle is completely open.

According to some manufacturers a cold air intake can add as much as 5 to 20 horsepower. But if you want to have more increase in power you can add a new exhaust. Ask an Expert.

F1 cars have used ram air,its only worth 1 to 2 psi at to kph do you drive around at these speeds alot? Keith again, sorry for the stupid typos!!!! Iy depends on naturally aspirated tur o charges ect. Combiningbwith cat back exuast can or encloswd air box ect. Its all variables…and dont forget calonration tunning.

Might want to actually show some cold air intakes then. The filter needs to be somewhere the engine bay is not…. My question always comes back to…. It would give an edge over competition. My mustang keeps running like crap and dies. But it will start right back up and run for a bit again. Could it be the air flow system not working right. I had in my Silverado 5. I liked it a lot my fuel went from 18 to mpg but I have gone threw 3 mass air sensors and one in each bank of my motor.

So with another appointment on Monday for another mass air sensor being installed. I put my factory air box back on and the engine light came off. I will miss the mpg improvement but not changing sensors. I wonder if any one else had any issues?

I think a CAI on a turbo or supercharge engine is a waste of money…because the turbo will heat up the cold air way past the income air temperature,, thus negating CAI efficiency…Past the turbo, you go to the intercooler, which is the real place the air gets cooler…Bolt on a BIG ASS intercooler, and tune the intake to it and you will see far better results Grandpa Bill, Austin , Tx.

Hi Graciosos Grandpa Bill! I created and installed a cold, RAM air intake in my turbocharged Abarth which not only brings in the coldest outside air available, it ALSO brings it in under PRESSURE because the TWO inlets are positioned down low in the grill facing directly forward where they receive direct air flow from the air being rammed into them by the forward movement of the vehicle!

The inlet holes are the two fog light openings in the grill. Then the air is ducted up and back into the engine compartment through smooth plastic tubing. The faster you drive? The higher the pressure! What does that mean? Instead it is being force fed the air.

So, due to the pressure of the air being forced into the turbo AND the fact the air is the coldest ambient air available, the turbo had less lag since the pressurized air helps accelerate the impeller AND the density of the incoming air is higher because it is ACTUALLY cooler for to the fact it is REAL outside air that is NOT coming in from the plenum area behind the grill out from a fenderwell. At 65 degrees outside ambient air temperature, gas mileage at 80mph cruise increases from 30, to 32mpg.

And horsepower when you want to accelerate? When the outside air temp is 55 degrees? It seems to plateau after that but winter performance is phenomenal. And warm weather performance is improved also. Since the engine puts out hp, that is a warm day increase of 8hp. Think of a factory air intake system as like having a cold that clogs up your head and restricts your breathing. Now go running. It's not going to work very well is it? A cold air intake is like amazing medicine that allows your engine to finally breath.

Cold air intakes move the air filter outside of the engine compartment so that cooler air can be sucked into the engine for combustion. Cooler air brings more oxygen denser air into the combustion chamber and that means more power. The filters are usually moved to the upper wheel well area or near a fender where there is more access to free flowing, cooler air and less hot air from the engine.

Not only does a cold air intake reduce the air temperature, but it also increases airflow. Aftermarket intakes remove the need for a box surrounding the air filter and instead use large diameter intake tubes that are smoother, have less bends and are often wider than the original factory ones.

Removing the air box and using smoother tubes gives the engine uninterrupted airflow. Cold air and more air sound good in theory, but no one gives a hill of beans about theory when you're trying to pass someone on the highway.

The good news is that although claims of actual horsepower and even increased fuel efficiency may vary, cold air intakes will in fact help increase your car's performance. By itself, you'll probably notice an increase in power when the throttle is fully open.

Some manufacturers claim as much as a 5- to horsepower increase for their system. But if you team up the cold air intake with other engine modifications, like a new exhaust, you'll create a much more efficient system.
