Having been on the market for over a decade, the AIRAID 520-152 CAD intake remains a popular choice for Nissan Titan and Armada owners looking for quick and easy ways to improve performance and efficiency of the potent 5.6L V-8 engine.
Nissan’s foray into the full-size truck and SUV world has been solid over the years, with both the Nissan Titan and the Armada having a faithful following. The 5.6L V-8 engine in these trucks makes plenty of power, and the overall styling and interior all adds up to solid trucks and SUVs that remain popular. Nissan wisely chose to leave well enough alone with these popular trucks, meaning they are essentially unchanged across a nearly 10-year span. But like all vehicles, there’s always more power to be found under the hood, and Titan and Armada owners have long-ago figured out that a cold air intake system is a quick and easy way to wake up the 5.6L and improve power. AIRAID was one of the first to market with a cold air dam system for these trucks when they were released in 2004. Dubbed the Quick-Fit, it was an affordable, easy solution to picking up performance. AIRAID has subsequently released a more fully featured MXP cold air intake system for 2004-2014 Titans and Armadas with the 520-284 intake, but the original 520-152, 521-152, 522-152, and 523-152 CAD systems remain popular, cost-effective solutions for improving performance and efficiency for Nissan full-size trucks.
To tailor the intake system to individual tastes and build preferences, AIRAID offers the 522-152 system that includes a Synthamax non-oiled filter in black, as well as a 523-152 system with a blue filter. The intake kit is also available with red oiled or non-oiled filters.
The AIRAID cold air dam system works by targeting the most restrictive portion of the factory intake system: the air box and air filter. New cold air dam panels replace the upper portion of the factory intake box. They snap into the lower half of the factory intake box, enabling the system to retain the use of the factory cold air inlet duct in the fenderwell. Weather stripping is positioned on top of the CAD panels that seals against the hood when it is closed; the system uses the hood as the “lid” for the air box. These panels keep the filter isolated from hot engine compartment air while also adding a very large forward-facing area for additional cool outside air to reach the filter. The panels also create additional room for a larger air filter, which is the key part of improving performance.
The Nissan Titan and Armada intakes utilize a 700-458 premium AIRAID cone-style filter, which is a key ingredient for improving performance. Featuring a flange diameter of 4 inches and a 7-inch length, the filter is sized perfectly to feed the 5.6L V-8 engine for thousands of miles without restricting airflow.
A special filter adapter was developed for the Titan and Armada that connects to the AIRAID CAD panels. This filter adapter incorporates a mount for the factory MAF sensor, which is transferred from the original air box to the AIRAID piece. It enables the factory intake tube to be retained and is also sized to accept the premium AIRAID filter inside the revised air box configuration. As with most AIRAID systems, the modifications are simple and require no drilling or trimming, making it easy for the vehicle to be returned to stock if desired.
The unshrouded design of the AIRAID CAD system allows a more direct path for cool outside air to reach the engine, but it also means dirt and contaminants can reach the filter. Consider adding a 799-456 pre-filter, which extends filter service intervals and keeps larger debris away from the air filter itself. The AIRAID pre-filter can simply be rinsed off periodically.
The heart of the system is the AIRAID premium filter, which improves airflow without sacrificing filtration. The AIRAID cone-style performance filter offers more surface area for filter media compared to the factory flat-panel paper filter, which means the filter is capable of flowing more air without introducing restrictions to the intake system. The AIRAID Quick-Fit system for the Titan and Armada (and Infiniti QX-56 variant) is available with four different filters. The 520-152 system includes a red filter with AIRAID’s SynthaFlow oiled filter media, while the 521-152 system includes a red filter with AIRAID’s SynthaMax dry filter media that does not require oil. The 522-152 system includes a SynthaMax dry filter in black, while the 523-152 system includes a dry filter in blue. These filters filter the same and flow within 5% of one another, so the best filter to use really depends on personal preference. All of AIRAID’s filters are washable and reusable while carrying a lifetime warranty.
