An AEM ETI module is like an electronic mediator, keeping both the MAF sensor and ECU happy allowing AEM to take full advantage of larger air intake tubes and improved performance

An air intake system is designed to increase power by reducing air intake restriction and turbulence. It’s pretty common to find that an aftermarket air intake system uses larger diameter air intake tubes than what comes from the factory. This is very effective at reducing restriction in the air path, but when a larger diameter intake is used on modern cars equipped with a mass airflow (MAF) sensor, it can create confusion for the engine control unit (ECU). This confusion will often lead to a check engine light and/or drivability issues.

When it comes to installation the AEM electronically tuned intake module is a simple plug and play solution using factory connections and does not require any cutting or splicing

Larger diameter tubing is capable of delivering a greater volume of air, but at the same time this can confuse a vehicle’s ECU due to improper MAF sensor readings. Without getting too technical, based on Bernoulli's principle, airspeed will decrease as the size of air intake tubes increase. Slower air speed will cause the mass airflow sensor to send inaccurate readings to the engine control unit. The ECU will then attempt to compensate by adjusting the amount of fuel injected into the cylinders.

Installing and using an AEM ETI is simple, yet AEM uses advanced technology on the inside of the electronically controlled intake module for increased performance

Before the AEM electronically tuned intake, a properly designed short ram intake, or cold air intake, would use mechanical methods of increasing air speed, such as reducing the tube diameter, as it passes through the MAF sensor. While this is effective at preventing check engine lights, it has two negative side effects. First, this usually causes a point of restriction in the air intake tube, and second it creates turbulence in the airflow. Reducing restriction and turbulence are supposed to be the two goals of an aftermarket air intake system.

With an AEM Electronically Controlled Intake (ETI), there is no need to detune an air intake system. The ETI module included with every AEM ETI air intake is designed to communicate with the mass airflow sensor and the ECU. Think of an AEM ETI module as a mediator, keeping both the MAF sensor and ECU happy. This allows AEM to take full advantage of larger air intake tubes and improving performance without the hassle of aftermarket tuning or the risk of drivability issues.

Not every car or truck needs the aid of an AEM Electronically Tuned Intake module for enhanced performance. Use the Search by Car or Truck tool to find an AEM air intake system for your vehicle and see if an AEM ETI air intake is available.

The AEM performance cold air intake system for the 2003-2009 Toyota 4Runner 4.0L V6 increases performance and leaves all the stock emissions control equipment in place

While early Toyota 4Runner models weren’t much more than a Toyota Pickup truck with a camper shell on the back, subsequent generations have transformed the 4Runner into a mid-size semi-luxury SUV which still retains some of its original off-road capabilities. While most the 4Runner’s competitors have switched to uni-body construction crossover SUV’s, the 4Runner still retains a body-on-frame design.

Toyota equipped the 2003-2009 4Runner with the 4.0 L 1GR-FE V6 engine rated at 245 horsepower as standard equipment. A 245 horsepower V6 isn’t anything to laugh at, but who wouldn’t want to bolt on a few more ponies? This is why AEM Intakes designed cold air intake system 22-682C for the 2003, 2004, 2005, 2006, 2007, 2008, and 2009 N210 fourth generation Toyota 4Runner 4.0L V6. This Cold Air Intake System is precision-engineered to provide a noticeable increase in horsepower, better acceleration, and improved engine sound for the Toyota 4Runner.

AEM CAI, number 22-682C, uses an AEM Dryflow air filter, and gray powder coated air intake tubes to draw from the factory cold air inlet in the 03-09 Toyota 4Runner wheel well

The AEM cold air intake system for 2003-2009 Toyota 4Runner V6 models is a little different from the average cold air intake system. AEM Intakes designers chose to retain the use of the stock air filter box when designing the 22-682C cold air intake system. Retaining the stock air filter box allowed AEM Intakes designers to increase performance while keeping inlet air temperatures, and air / fuel ratios within factory specifications. Utilizing the stock air box maintains the use of the factory cold air inlet near the front wheel, allowed the CAI system to retain all factory air intake connections, as well as leaving all the stock emissions control equipment undisturbed.

Testing revealed that the factory air intake ducting was partially to blame for intake tract restriction in the stock system. Included in the 2003-2009 Toyota 4Runner 4.0L V6 cold air intake system is a free-flowing mandrel-bent aluminum intake tube which helps to reduce the restriction found in the stock air ducting, and allows the engine to breathe easier. Restriction isn’t the only trouble with the stock air intake as it also creates turbulence in the incoming air. The mandrel-bent aluminum intake tube used in this cold air intake has a smooth and consistent internal circumference for reduced airflow turbulence. To ensure that the cold air intake tubes will look great for years to come, it is finished in a charcoal gray powder coat. A custom designed air accelerator is affixed to the end of the air intake tubes and is then inserted into the factory cold air intake source in the wheel well. This ensures that the 2003-2009 Toyota 4Runner 4.0L V6 draws cool, fresh, and more dense air from outside the engine compartment.

AEM Dryflow air filters are designed to flow more air than typical paper automotive air filters, and because of this AEM synthetic air filter, number 28-20281, is able to reduce restriction inherent to using stock disposable automotive air filters. Advanced AEM Dryflow, non-woven, oil free, synthetic air filter media is at the heart of the replacement AEM air filter for 2003-2009 Toyota 4Runner V6 models which allows for easy cleaning, durable service, and excellent filtration without the need for air filter oil.

All of the design features of the 2003-2009 Toyota 4Runner 4.0L V6 cold air intake system work together to deliver increased horsepower, torque, and improved acceleration. On the dyno, 22-682C produced an estimated 6 more horsepower at 5,200 rpm and 5 pound-feet of torque at 5,200 rpm over the stock system. Additional horsepower and torque can come in handy when merging onto a highway, towing, or trying to tackle an obstacle off-road.

Due to its retention of a body on frame design, the Toyota 4Runner is considered a mid-size semi-luxury SUV that still retains some of its original off-road capabilities

An AEM performance cold air intake system is an excellent upgrade for 2003, 2004, 2005, 2006, 2007, 2008, and 2009 N210 fourth generation Toyota 4Runner models with a 4.0L 1GR-FE V6. This is a complete cold air intake system including all the necessary hardware and step by step installation instructions.
