After replacing icv,intake boot,valve cover gasket and return to stock air box from CAI,car will not hold idle 325i 1994

Where does the air go after the intake?

Located directly behind the front grille, the air intake system draws air through a long plastic tube going into the air filter housing, which will be mixed with the car fuel. Only then will the air be sent to the intake manifold that supplies the fuel/air mixture to the engine cylinders.

Will cold air intake damage my engine?
But a lot of times let me put these cold air intakes on they're actually sucking in hotter air. As in this case. It's sucking at hot air that's running under the engine where the old factory.

Does air enter the engine through the intake manifold?
System is the intake manifold. And the fuel injector set over here now it's job is basically to take all that intake air here and mix it with fuel spray that's coming from the injectors.

Will a cold air intake make my car run lean?

Adding a cold air intake .. ANY cold air intake, should not throw codes or cause a lean condition. Lean conditions/codes happen when unmetered air “leaks” into the sysytem after the Mass Air Flow sensor – and before the T/B.

How do you force air into an engine?

Installing an intake manifold with taller and longer runners to help ram more air into the cylinders. Installing a larger throttle body or carburetor (or multiple carburetors) that can flow more CFM (cubic feet per minute). Adding an air scoop or cold air intake system to help route cooler denser air into the engine.

What controls the airflow in a car?

Q: What controls the vents in a car? The vents for modern vehicles are controlled by three or four electrical actuator motors, which can be adjusted by the climate control module; this electronically regulates and control the air ventilation system in your vehicle.

Does a CAI need a tune?

If you’re looking to add a cold air intake and tune on your car, the answer is no. You do not need a tune after installing a cold air intake. A cold air intake will give you more horsepower and torque off the line if installed correctly with an exhaust system that has been tuned for it.

What happens if you install a cold air intake wrong?

One of the most common symptoms associated with a bad or failing cold air intake is a reduction in engine performance. The cold air intake also uses an engine air filter, which when clogged or dirty can cause a reduction in power, acceleration, and fuel efficiency.

Can a cold air intake damage your transmission?

Can A Cold Air Intake Affect Your Transmission? In most cars, it will be installed on a manual or automatic, as the cold air intake does not affect the gearbox or any other mechanical system.

Will adding a cold air intake throw codes?

You should not throw codes or lean your body if you intake cold air. When unmetered air leaks into the sysytem after the Mass Air Flow sensor – and before the T/B – Lean conditions/codes are observed.

Can your engine get too much air?

What Happens If Too Much Air Gets In The Engine? A car can become lean when it runs too fast because it is breathing too much air, and the fuel is burning too quickly since there is too much air. Because of this, the combustion will have less of a motor to move the cylinder.

What does a Spectre cold air intake do?

Spectre’s muscle car air intake systems are designed to increase horsepower and torque. These air intakes are designed to increase performance by routing the intake inlet away from heat sources like the radiator and headers.

Is K&N better than Spectre?

They have a point, considering that Spectre filters deliver similar results on a better price tag. K&N’s strong point is the increased air flow (high-flow design) and the fact that their filters are washable. The airflow increase, however, can turn into a drawback if you drive in areas especially high on fine dust.

How much HP does an air intake add?

5-20 horsepower

Cold Air Intakes are said to improve your vehicle’s performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn’t enough power to put you back in your seat, it will give your car or truck a little pep in its step.

What are the pros and cons of a cold air intake?

The cold air intake does typically get denser air than the stock intake. However, since it is longer and more requires more complex routing, it is often more expensive. This increased complexity also leads to a more difficult and time-consuming installation.

Is a cold air intake better than stock?

The free-flowing inlet pipe allows less turbulent air that is moving faster and contains more oxygen than stock systems. Well-built systems can increase both horsepower and torque and can improve fuel mileage as well. A cold air intake usually makes an engine louder because the larger volume of air is less restricted.

Is a closed cold air intake better than an open one?

The closed cold air intake comes in more potent than its open airbox sibling. It has the ability always to keep intake air temperatures the lowest possible when running very hard, whether you’re at the track or on your favorite twisty backroad.
