Magnum Force™ Stage 2 Cold Air Intake System by aFe®. The aFe Stage 2 Cold Air Intake System replaces your entire factory air intake system with a large high-flow aFe air filter, open element airbox/heat shield and a smoothly contoured, less restrictive intake tube. This system enables your engine to take in huge quantities of dense, cool, oxygen laden air. The result is better combustion, increased horsepower and torque, and a noticeable gain in performance.

The Stage 2 Cold Air Intake System will give you the greatest possible performance gain and the most bang for the buck. It replaces your factory, restrictive air intake system with the massive aFe performance air filter of your choice, a one-piece open element airbox/heat shield that seals against the hood, isolating the filter from engine heat, and a rotomolded plastic intake tube with smooth bends for increased airflow volume. The increased flow of cooler air to your engine will result in noticeable gains in power and performance. Cooler, denser air contains more oxygen, and more oxygen in your engine's air intake charge means better combustion, resulting in greater engine output.

The aFe Pro 5R air filter was designed to provide the maximum airflow possible, to enable your engine to make the most horsepower and torque. But aFe didn't achieve this by ignoring engine protection. The Pro 5R outperforms most other cotton gauze air filters with a 98.6% efficiency rating. The increased airflow and high filtration capability are the result of the Pro 5R's construction. It’s made of 5 layers of progressively finer medical-grade cotton gauze.

The Pro GUARD 7 air filter delivers increased airflow while providing the highest level of filtration efficiency available – 99.7%. The patented 7-layer progressive cotton/synthetic media in the Pro GUARD 7 consists of 5 layers of progressively finer medical grade cotton gauze, combined with 2 layers of non-woven synthetic polyester fabric with random porosity.

Competitors use constant size mesh gauze in their filters, which creates voids/openings that can allow dirt to pass through. As the progressively finer layers of gauze are stacked in the Pro 5R and Pro GUARD 7, the randomness of the openings increase, minimizing spaces with no filter media. Dust accumulates on multiple layers, increasing overall dust holding capacity and filtration efficiency.

The Pro DRY S filter combines high airflow and filtration efficiency with the convenience of oil-free maintenance. It contains 2 layers of randomly porous synthetic fabric, which allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.

The pleats in all 3 filters are evenly spaced for greater dust holding capacity and the tips are rounded for better airflow. They're also 30% deeper than comparable aftermarket air filters for longer service intervals and greater dust holding capacity. The sealing surface and supporting structures are made from 100% polyurethane, to withstand extreme engine temperatures.

The one-piece airbox/heat shield is made of rugged 16-gauge powder coated steel. It installs easily in place of the factory airbox; no cutting or drilling is required. The box/shield is attached with quality stainless steel hardware that is supplied with the kit. Top quality, flexible rubber trim at the top of the box/shield seals against the hood when it is closed, shielding the air filter from engine heat and allowing it to take in cooler air. Some systems include a powder coated steel or brushed aluminum cover to further shield the filter.

A specially developed 3-angle velocity stack smoothes the airflow transition from the air filter to the rotomolded intake tube. The precision design and smooth contours of the intake tube maximize airflow volume and speed for optimum power gains.

The aFe Stage 2 Air Intake System comes complete with everything necessary for installation, including comprehensive instructions. It's backed by aFe's limited 2-year warranty and made in the USA.

Keep The Bugs Out
I always ordered these filter covers so I didn't not have to dig all the bugs out of the filter itself.

Great Product!
Really dresses up under the hood and install is easy. Installed this and exhaust at the same time so haven't seen if there was a mileage boost due to loving the new sound of the truck and staying on the pedal lol!

aFe Products Are Solid!
Unlike some air intake kits, this one was very easy to install. It took about an hour to take my old one out and install this one. It looks awesome and once you start your truck, you can hear it breath better!! I've used k&n and air raid on other vehicles and I would totally choose aFe!

Cold Air Intake
I absolutely love my purchase of this Cold Air Intake. I can feel so much of a difference in my 06 350Z. More torque and quite a few horsepower gains as well. Also, the appearance of the blue air filter matches the color of my car which is always a plus. Ease of installation, this was my first cold air intake install but I still could've done it in my sleep.

Perfect Fit
It's a product designed to perfection. Because it takes less than 10 minutes to install it. It took me longer to unwrap it from the box than installing it. Everything fits exactly as it was designed to fit. About performance you will notice the difference once you install it and every time you accelerate it emits a sound, like Woooow! An amazing sound! I had the opportunity to install another brand and the results were negative. The price was expensive but it's worth it to other brands in the market. You will not regret in purchasing this brand. I am very pleased with my purchase and also with the AFE tech support, they were very professional! Jose Sahagun from California.
