WHY TO BUY?

Your vehicle's engine is essentially a giant air pump; it sucks in air at one end and spits it out the other. The better it can do this, the faster your ride can go. So as you can see, improving air flow is crucial to maximizing engine power. One of the best ways to boost power and efficiency is by using International Harvester performance plenums for your engine. Stock OEM-type plenums can be very restrictive to incoming air, but International Harvester performance plenums are designed to supply increased air with better flow characteristics, which translates to improved horsepower and torque. So if you want your vehicle to blow away the competition, check out our extensive line of International Harvester performance plenum options.

DID YOU KNOW?

Performance Plenums are designed to give maximum air flow but there are several additional benefits that are worth mentioning. Many performance plenums are constructed of different materials than the OEM units to provide additional strength and reduced weight. In addition these International Harvester performance plenums boast increased volume which not only helps with flow characteristics but can also drastically reduce the temperature of the intake charge. A colder charge means more power and reduces the chances of your engine suffering from heat soak. Lastly performance plenums give great distribution of air to all cylinders so that you won't risk running one cylinder rich or lean, but will instead have nice even performance.

FAQs

Q: What is a performance plenum? Why buy one?
A: The plenum is the portion of your engine’s intake setup between the throttle body and the engine block. Air flow efficiency through this area of the motor is crucial for making horsepower. Performance plenums are designed to drastically improve air flow characteristics to give the air coming into the motor the most direct path with the least amount of restrictions and disturbance. Remember, a motor is nothing more than a giant air pump, so this increase in flow can mean tremendous gains for your engine. With substantial improvements in power and efficiency performance plenums offer excellent bang for the buck. They work well for both naturally aspirated and forced induction vehicles and also will give your engine a great custom look.
