Air Intake and Fuel Delivery Parts for Ford F-250

Before replacing or modifying the air intake system on your Ford F-250, there are a few things that are good to know. Installing a new intake system can help to add horsepower and torque, and it may even go so far as to make your F-250 more efficient in its use of fuel. Additionally, many aftermarket and OEM (original equipment manufacturer) air intake kits come equipped with functional filters that can add to the overall ergonomic ability of your trucks engine.

How do air intake systems increase horsepower?

Air intake systems can help to increase your horsepower in a few ways. Adding or modifying your cold-air intake system is one of the quickest ways to increase your trucks horsepower. Heres how it works:

  • Moving the filter - A cold-air intake system moves the engines filter away from the engine. This makes it possible for the air being sucked in to cool down better. Cooler air carries more oxygen and allows your vehicle to consume fuel at a better rate.
  • Increasing airflow - An aftermarket cold-air intake system will usually have a better filter that allows air to pass in a less restricted manner.
How much horsepower can an air intake system add?

An aftermarket air intake system can actually add up to 20 ponies of horsepower. This is pretty significant, considering that these systems are so easy to install. Common manufacturers of aftermarket intake parts include ACDelco, Airaid, Bosch, Delphi, Dorman, Motorcraft, and Spectra Premium.

How do cold-air intake and exhaust systems differ?

There are a couple of key differences in the ways that air intake systems function:

  • Exhaust systems - Your exhaust system removes used gases from around your cylinder and expels them from the vehicle.
  • Cold-air intake systems - These systems increase airflow by allowing air with reduced temperature to be funneled to the engine, resulting in increased power.
Which intake parts may need replacing on your Ford?

The parts that make up your vehicles cold-air intake system tend to wear out at different rates. A Super Duty pickup like a Ford F-250 will have a few intake parts that will probably need to be replaced rather frequently. This is especially true if youre using your Ford for hauling heavy loads or driving it in certain rough terrain conditions. These parts are likely to require replacements:

  • Air filters - Air filters and air filter parts should be replaced regularly. If youre driving on dusty dirt roads, your air filter probably gets full pretty quickly. The plastic and metal parts that hold your air filter down will wear out a bit more slowly.
  • Tubes - Intake system tubes will also need to be changed. They can become clogged, corroded, and damaged over time when hauling material or heavily engaging your trucks throttle.
  • Fuel pumps - A bad fuel pump can decrease your gas mileage and put the engine under a dangerous amount of stress, even compromising your vehicles ability to function. Faulty fuel pumps should be replaced immediately.
  • Fuel injectors - A fuel injector is essential for maintaining optimal gas mileage and minimizing your emissions. A bad fuel injector may cause you to fail an emissions test and severely compromise your engines performance.
