AEM Brute Force Intake System B.F.S. JEEP CHEROKEE 91-01 4.0L

The AEM 21-8315DP Brute Force Air Intake System produces horsepower and torque gains by replacing the vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Jeep Cherokee models. Air enters the system through an extra-large AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable chrome-like finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the crankcase breather hose. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards while others are 50 state legal.

AEM's Brute Force Air Intake Systems are tuned and dyno-tested to give your engine more power and acceleration by replacing the restrictive factory air filter, air intake tubing and air box assembly.

Air intake systems are a common first mod to many project cars. They are quick and simple to install while also enhancing the looks of your engine bay, the sounds of your engine, and the performance of your vehicle.

We often recommend upgrading your OEM intake to a cold air intake as one of the first modification your should do to your car. Often times, the factory airbox is restricting. Replacing your intake system with an aftermarket unit will increase intake noise, performance, and improve your overall driving experience.

AEM was founded in 1987 by John Concialdi (J.C.) and Bob Sullivan as a tuning performance shop. The shop focused on vintage automobiles and the latest trends in street racing modified imports. With it's location in Compton California, AEM was embedded in the tuner market from the very beginning. It was a matter of being in the right place, at the right time, with the right technical knowhow. Between J.C. and Sullivan, AEM had two important advantages. Technical engine knowledge and massive creativity fueled by an unbridled passion to make things go faster. When it came to understanding air flow through an engine, few had more experience than Concialdi. He managed the R&D department for Weber Carburetors for North American aftermarket applications the previous 10 years. By 1993 when the shop relocated to Gardena California, AEM had the reputation as a modifier of choice. The business had grown so much that at times it ran 24 hours a day. Racers depended on AEM to have cars ready for the next street race or sanctioned event. Cars and drivers sporting AEM’s bright yellow logo became famous in the street racing scene for one consistent reason, they won races. AEM’s first glimpse of mainstream notoriety came when cars tuned by their shop won at the “Battle of the Imports”. This highly contested shoot-out landed AEM on the cover of Turbo Magazine and Sport Compact Magazine. Many of the most visible drivers in import street racing ran cars modified by AEM. This included names like Adam Saruwatari, Tony Fuchs, Brian Kim and Darin Ishitani, Archie Medrano, Russ Matuseavich, Abel Iberra, Miles Bautista, E.T. Saffon. AEM developed one of the first Packaged Air Induction Systems. It's design came from their experience in dyno testing, understanding intake energy dynamics and racing at the Battle of the Imports. AEM’s presence in the tuner movement and its proximity to Nissan, TRD and Honda allowed them a unique opportunity. There was an advantage to living side by side with racers and working with OES engineers. AEM was able to understand both the practical and theoretical side of engine performance. AEM's first air intake kit was offered for sale in 1994 as a "Do-It-Yourself" upgrade for the Honda CRX. This intake proved to be the beginning of a whole new tradition. People could suddenly purchase affordable cars and modify them for increased torque and horsepower. AEM has been a leader in the development of precision tuned induction systems since the Battle of the Imports. Today, the Company’s induction systems number in the hundreds. AEM is still the one to beat.
