Deep cotton pleats and a rigid outer mesh make the AFE air filter better able to deliver air to your engine while withstanding tough conditions
A full AFE intake on your ride can boost power and torque by delivering cooler, denser air to your intake manifold
The AFE Proguard 7 filter uses seven layers of filter media to deep clean your diesel engine's intake air
Even when wet, the AFE Proguard 7 filter won't collapse and damage your diesel, unlike lesser paper or cotton air filters
The concept behind the AFE air filter is pretty simple, really. An AFE air filter uses the same design philosophy used on air-cooled engines. The more fins you have, and the deeper those fins are, the more cooling air you get. In the AFE air filter, the more pleats in the material you have, and the deeper those pleats go, the more intake air you get. It's all about surface area, and the AFE air filter has more surface area for filtration and air intake than the competition. An AFE air filter then incorporates several layers of premium surgical cotton gauze to act as the filter media itself. When oiled, cotton gauze like that used in the AFE air filter is extremely effective at trapping even minute dirt particles and keeping them trapped until the filter is washed. And if a larger object happens to make it to your intake, the AFE air filter has epoxy-coated mesh on both sides of the AFE air filter surface to prevent entry into the intake tract. Finally, the AFE air filter is capped with a pure urethane foam seal that resists underhood heat more effectively. After all, what good is a lifetime filter element if the foam seal breaks down after a few years? Instead, the high-flow AFE air filter is designed to last the life of your car and your engine, and that goal has been kept in mind in the design of every AFE air filter part.AFE, or Advanced Flow Engineering, knows that not everyone wants, or can afford, a full-bore AFE cold air intake system. That's why they offer their AFE cold air intake in two different versions for many applications. The Stage 1 AFE cold air intake incorporates the company's advanced high-flow air filter along with a replacement airbox or heat shield, depending upon application. The air filter in every AFE cold air intake features deep pleats of surgical cotton gauze for exceptional filtration and high flow, and is reusable for the life of the car. The Stage 1 AFE cold air intake is a replacement for just the intake section of your vehicle's induction system and will utilize stock plumbing from the airbox to the intake. For the next step in performance, move to the Stage 2 AFE cold air intake. This AFE cold air intake contains all the components of the Stage 1 AFE cold air intake, but also adds a precision-molded intake runner extending all the way to the intake manifold or turbo. The Stage 2 AFE cold air intake gives the most possible power by using non-conductive materials in all the plumbing. That means cooler air, more air flow, and more horsepower to your drive wheels. There are tons of applications available, from sport compact cars to diesel trucks, so see if there's an AFE cold air intake for your vehicle today!Are you running a diesel engine in your truck or SUV? You need to take a look at the AFE Proguard 7 air filter. As the name implies, the AFE Proguard 7 filter has seven layers of progressively finer medical cotton gauze making up its filter media. That makes for exceptional filtration even at the high intake pressures experienced by diesel engines. The AFE Proguard 7 filter then sandwiches that filter media between high-strength steel mesh to keep it in place regardless of how much boost your engine seeseven if it gets wet! The AFE Proguard 7 has a durable but flexible polyurethane seal surrounding the filter that ensures you get an airtight seal without having to resort to sealants or other gaskets, and the polyurethane construction of the entire AFE Proguard 7 filter keeps engine heat and environmental pollutants from breaking down your AFE Proguard 7. The end result is that with an AFE Proguard 7 filter installed, you can see improved fuel economy, more power, more torque, and longer engine life, all from an air filter. And since you sign the monthly checks for that truck, you should know that everything you can do to prolong the life of your diesel is money well spent. Invest in an AFE Proguard 7 air filter for your diesel and reap the benefits in both the short term and the long term.
