Advanced Flow Engineering, Inc. (aFe) produces high flow, high performance air filters for the automotive industry. Founded in April 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter. aFe is a team of engineers, machinists, production and sales people who believe in the product they design. They each have years of experience in their respective positions and together work to ensure that they have the best product on the market. Their purpose was not just to be another vendor that offers air filters, they chose to pay attention to those finer details that set and aFe filter apart from the competition. They currently offer aftermarket air filters for passenger cars, light trucks and SUV's. aFe also has many applications for round racing and universal clamp-on filters.

COLD AIR INTAKE KITS

Cold Air Intake Systems

Are you looking to increase your engine's power? Then start at the top...

aFe has designed three different air intake systems to meet the needs of your power hungry engine. For the largest possible performance gain replace the entire air box and intake tract with our STAGE 2 open element air intake system. If you want to maintain a factory appearance the STAGE 2 Si sealed air box provides quiet power. For a great value and easy installation our STAGE 1 air intake systems adds instant horsepower and torque.
AIR INTAKE SYSTEMS
Airflow / Volumetric Efficiency
Huge, high-flow conical air filters are the first step to increased airflow to the engine. Steel heat shields or molded plastic air boxes keep hot air out and fresh, cold air flowing to the filter. Velocity stacks and precision-designed intake tubes provide smooth, uninterrupted airflow to the turbo or throttle body.

FEATURES and BENEFITS

MORE HORSEPOWER / TORQUE

• Medical grade cotton gauze filter media reduces air restriction and increases engine output.
• Surface area optimized to reduce pressure differential across the element resulting in reduced backpressure and increased torque.

INCREASED AIRFLOW

• Precision pleat geometry optimizes airflow through intake system.
• Engineered to control maximum filter face air velocity with deep precision pleats.

IMPROVED ENGINE PROTECTION

• Multi-layer oiled cotton gauze attracts and traps contaminants without sacrificing airflow.
• Sturdy epoxy coated wire mesh construction protects filter media (and engine) from large debris.

LONGER FILTER LIFE

• Cleanable and reusable.
• Urethane seal outlasts conventional materials (especially under extreme engine temperatures).>
• The last filter your vehicle will ever need.

LIMITED LIFETIME WARRANTY

• aFe OEM Replacement Filters carry a limited lifetime warranty against material and workmanship defects for as long as the original purchaser owns it.
• aFe Universal Racing Filters carry a one-year warranty on material and workmanship defects.
• Damage from abuse, improper cleaning and open flames are not covered under warranty.

TECHNICAL INFORMATION

Pleated Material

The aFe air filter uses deeper pleats than the competition. Using deeper pleats means more pleated media, resulting in more surface area for air to flow through while reducing its restriction. The aFe air filter is able to achieve this without choking airflow using a precision crafted pleat pitch, allowing smoother airflow into the engine. Competitive products, while attempting to increase surface area, over pack the filter with excess pleats, thus resulting in the unfortunate side effect of choking airflow. The aFe filter media, with its uniquely designed pleat depth, pitch and media material, prevents air velocities at the filter face from reaching critical speeds. Exceeding critical speed result in increased backpressure and reduced engine performance. It also improves filter longevity by allowing for better dust retention.

The pleated media sandwiches multiple layers of high quality surgical cotton gauze between two layers of aluminum wire mesh. The special oil-treated surgical gauze filters out contaminating particles with less physical obstruction than typical paper elements. The oil is absorbed and wicked through micro fibers of the surgical gauze. Suspended particles are filtered out of the air stream through static charge attraction with the gauze/oil media. The aluminum wire mesh serves two purposes: first, it removes and prevents large solid particles from entering or damaging filtration media: and second, it provides a lifetime structural skeleton for the filter.

The aFe air filter is simply more efficient than competitive products. Multiple discrete layers facilitate depth filtration, which contributes to efficiency and promotes longevity over paper filters, which depend on quick clogging surface filtration. In addition, oil in the media enables the cotton gauze to filter out particles at a higher degree of efficiency without restricting airflow.

Seal Design

The aFe air filter features a superior seal design with a 100% polyurethane material construction. Poorly designed seals either permit air leakage or distort the filter housing. Many other filters use plastisol or air/foam seals. Over timer, heat and chemical attack cause this material to lose its elastic characteristics, which result in seal failure. Complex curing processes also prevent consistent quality manufacturing of plastisol. Since visual inspection cannot distinguish between a good quality (fully cured) and out of specification seal (not cured), the problem is not detected until the seal fails in service. On the other hand, foam type seals simply cannot pass the test of time. Use of a foaming agent reduces the amount of polyurethane used in the part. Minimal heat exposure tends to turn this material into powder.
