How Soon Should I Change The Air Intake System In A New Porsche?

OEM air intake systems have quickly become popular Porsche engine modifications for late Porsche models. A simple question to ask is why are they so popular today? After all, didn’t automotive engineers who worked on your vehicle spend months and may be even years developing high quality engine compartments? Since fuel economics as well as power are critical selling points today, it is impossible to imagine car manufacturers ignoring how much car owners want to maximize miles per gallon, horsepower or even both. Read on to learn more.

Power And Mileage Economics

Truth is, the typical air filtration systems that come with new cars are designed as compromise. Because of this, car owners miss out a mileage and power that could easily be gained. Your best bet is to therefore go for an OEM air intake. Place in in place of your car’s air box, filter and air hose.

The Basics

In layman’s language, the internal combustion engine is more or less like a large air pump. Air that contains mostly nitrogen and oxygen is pumped into the engine’s cylinders. Fuel is also pumped during the intake stroke before it is compressed and burned then forced out as spent or used gas. As this happens, even the least form of resistance during the exhaust or intake strokes robs some power from the engine. That explains why OEM air intake systems, less restrictive exhaust systems and exhaust headers are popular. They simply step in to ensure no power is robbed from intake or exhaust strokes.

Restriction Reduction

Because OEM air intake systems are effective at significantly reducing restriction, they easily reduce power robbing pumping losses. They also make it easy for the engine to take in more air. By strategically positioning the air filter in a prime location that is further away from the engine, OEM air intakes draw cooler and denser air with ease. This means the combustion chamber produces more power without adding complex moving parts.

The Compromise Factor

Notice how the word ‘compromise’ was used above to describe factor air intake systems. This does not mean in any way that the automotive engineers who designed your Porsche did not understand the aforementioned air intake basic principles. They simply had to take other factors apart from performance into account when they designed and fitted your Porsche with a factory air intake system.  To reduce engine noise, the vacuuming whine or airflow is easily quieted by restrictive air baffles.

The Surface Area Factor OEM air intakes feature conical air filters with large surface areas for a reason. The large surface area allows more air volume to be scooped into the car engine. The design also ensures that the scooping happens smoothly and without turbulence.  It gets better with the fact that fitting a new OEM air intake system is as easy as changing a light bulb. Be sure to contact your mechanic though if you’re not sure how to go about it. Then by all means, have the air intake system inspected at least once every two months.
