Phoenix-based Airaid started manufacturing air intake systems for light trucks and SUVs about a dozen years ago. By 2002, the company introduced a premium system incorporating new materials and technologies that improved on the traditional cotton-gauze performance filter. The heart of the intake system is the air filter with multiple layers of surgical-quality cotton gauze supplemented with an additional layer of nano-fiber synthetic, SynthaFlow, sandwiched between either stainless steel or aluminum mesh, depending on the vehicle application. SynthaFlow is moisture resistant and traps particles measured in percentages of a micron.
More specifically, Airaid says its filters trap twice as many two-micron particles and six times the 0.5 micron particles than other performance filters on the market. These tiny pieces of dirt play a large role in off-road rig engine damage, etching nasty hieroglyphics on cylinder walls and generally gunking up air, lubricant and fuel systems. The casings for Airaid's filters are industrial-grade, hand-poured urethane capable of withstanding the extreme temperatures that can build up under the hood.
Another obvious plus to a performance-intake system is increased airflow for more efficient combustion, a boost in horsepower and torque and better fuel mileage. The trick is maximizing both airflow and filtering capability - a trick Airaid has down pat with a combination of technologies including less restrictive, cross-linked, high-density polyethylene intake tubing to maintain a high volume of air into the combustion chamber.
Yet another feature incorporated into the company's systems is a cold-air dam (CAD) designed to keep engine heat away from the air intake. Some CAD intake systems use the stock filter location, but include a huge air inlet to increase cool air intake through the conical filter.
If the stock air box location isn't conducive to maximum airflow, the company's Classic Intake tubing and filter move the air inlet to an optimal spot. The Classic also offers a system splash shield for some off-road applications.
While all Airaid systems promise easy installation, the fastest way to improved performance is the QuickFit cold-air intake system. QuickFit kits include a premium filter and CAD, retaining the stock filter housing and air inlet. The dyno tests on this simple system show an increase between 20- and 200-percent in airflow, with gains in output from 6 to 16 hp, depending on the application.
Finally, Airaid hasn't forgotten your diesel tow vehicle. Over the last 10 years, improvements in diesel design led the company to add its own improvements to performance. Incorporating its CAD technology, Airaid's diesel intake systems provide an extra blast of cold, dense air to the engine, increasing both horsepower and torque and helping to feed the turbochargers.
If your off-roading requires an exceptional amount of torque and throttle finesse - we're thinking rock crawling or an affinity for highly technical climbs or even the addition of over-sized tires - Airaid's PowerAid throttle body spacer can supply a torque boost, especially in part-throttle situations. The key is the patented Helix Bore design, a spiral-cut groove on the inner surface of the spacer that spins the incoming air as it passes the throttle plates. The spinning air charge carries all the way into the combustion chamber, improving atomization.
The bottom line: significant gains in mid-range torque and fuel efficiency. PowerAid throttle body spacers are also available for carbureted applications. If your other car is high-performance speed mobile, check out Airaid's spacers with Powerports. These spacers (look for a "-1" at the end of the part number) are specifically located to allow for aftermarket performance upgrades like nitrous oxide or instrumentation sensors.
One of Airaid's claims to fame is its ability to be the first to bring new applications to market. The latest crop of applications include an MXP Series system for the 2009 full-size GM trucks and SUVs equipped with 4.8 and 6.2-liter engines, as well as '09 Chevy/GMC 2500-3500 trucks with the 6-liter engine, and a high-flow filter for the 2009 Ford F150, F250, F350 and Expedition with the 4.6, 5.4 or 6.8-liter engines.
What all this boils down to is simple: if you'd rather wear your off-road dirt on the outside of your rig, where it belongs, check out Airaid's series of intake systems. Your engine will thank you with not only longer life, but also a boost in performance and fuel efficiency.
