Without proper airflow, your truck isn’t going anywhere anytime soon. Many truck owners focus obsessively on improving their engines or their wheels, but you might be losing a lot of power if you have an air intake system that can’t keep up. If you want to actually improve your truck’s performance, check out some of these must-have air intake accessories that can help you out a lot.
While not necessarily an accessory, this is one of the ways you can fully upgrade your air intake system. Cold air is far denser and more oxygenated that warm air, which is why you want your air to be at a lower temperature before it reaches the engine. Cold air intakes are specially designed to prevent colder air from warming up on its way to your combustion chamber, delivering highly oxygenated air that can improve acceleration and power.
No matter what kind of air filter you choose, it’s still a must-have air intake accessory to consider carefully. An oiled air filter is the way to go if performance is your top priority, but it has drawbacks as well. Oiled air filters require more regular maintenance, and they don’t perform as well in extremely dry environments, such as desert-like conditions. A dry filter might be a better bet if you live somewhere very dry or don’t want to service it as often.
Your airflow indicator will be a crucial element of your air intake system, especially if you plan on doing maintenance yourself. The main purpose of these indicators is to help you understand the best time to replace your filter. Just because they perform a fairly simple function does not mean you should go for the cheapest option. These indicators can help you detect filter issues early on and protect the rest of your engine as well.
Even the piping itself is something that you can change and upgrade based on your needs. This upgrade is especially important for cold air intakes, as you want piping that you can trust to not get too hot and warm up your air. Polyethylene is a good material for air intake piping because it doesn’t conduct a lot of heat, keeping the oxygen-dense air from losing that oxygen on its way to your engine.
Depending on what you’re working with, Norcal Diesel Performance can help take your truck to new heights. Check out our 6.7 Powerstroke air intake system to see the difference that these components make.
A. The horsepower gains from a cold air intake can vary depending on your truck's engine and existing modifications. In many cases, drivers notice improved throttle response, better airflow, and modest horsepower increases because cooler, denser air contains more oxygen for combustion.
A. Oiled air filters are typically designed to maximize airflow and performance, but they require regular cleaning and re-oiling. Dry air filters generally require less maintenance and can be a better choice for drivers who frequently operate in dusty or extremely dry environments.
A. Replacement intervals depend on driving conditions, mileage, and the type of filter installed. Trucks driven on dirt roads, construction sites, or off-road trails may require more frequent inspections. An air flow indicator can help determine when service is needed rather than relying solely on mileage.
A. Yes. High-quality intake piping can help maintain smoother airflow and reduce heat transfer before air reaches the engine. This is especially beneficial for cold air intake systems, where preserving cooler intake temperatures is important for efficiency and performance.
A. Air intake upgrades can be beneficial even on a stock truck. Improved airflow may enhance throttle response, support engine efficiency, and prepare the vehicle for future performance modifications. Many truck owners start with an intake upgrade because it is one of the most straightforward ways to improve the engine's breathing capabilities.
