2011, 2012 and 2013 Nissan Altima Models Gains Horsepower from AEM ETi Air Intake Technology

2011 and 2012 Nissan Altima models with the 2.5 liter engine are sporty four door vehicles that are a blast to drive alone or with the family. The 2013 Nissan Altima Coupe with the same efficient 2.5 liter engine is even more sporty and all three of these vehicles can add more power and performance with an AEM air intake system. AEM started looking at the best ways to increase the performance of these Nissan Altima models. They found by utilizing AEM's ETi technology on their 41-1003P and 41-1003C air intake systems, the Nissan Altima gained an estimated 3 horsepower and 4 ft-lb of torque at 4900 RPM at the wheels over stock. Power was gained throughout the RPM range in this test.

Air Intake 41-1003P
AEM's 41-1003P (polished tube finish) and 41-1009C (gun-metal gray finish) ETi air intake systems come with all the necessary adapters and components for a fast and easy installation. These air intake systems include a mandrel bent aluminum air intake tube, heat shield, reusable Dryflow synthetic air filter, fresh air inlet tube, hose clamps, nuts and bolts needed to install it on one of the Nissan Altima models listed below.
AEM's Nissan Altima air intakes also provide connections for the mass air sensor and PCV connections.

These air intake systems utilize AEM's advanced ETi (electronically tuned intake system) technology which is designed to help improve air flow and reduce restriction. A lot of air intake systems use air flow modifiers like signal conditioners, ventrui inserts or smaller diameter tubes to make sure the mass air sensor reads the air correctly. The problem is these modifiers also cause restriction on the engine. Since the ETi module corrects the signal from the sensor to the computer, AEM is able to eliminate these modifiers. This allowed AEM's engineers to "super tune" these air intake systems for the Nissan Altima's 2.5 liter engine, sensor and computer setup, and gain more horsepower at the wheels.

The heat shield provides benefits by isolating the air filter, and the air that is being sucked into the engine, from the hot air under the hood, which can cause a loss in performance. The included fresh air inlet tube, which attches to the heat shield, is designed to replace the stock inlet tube with a more efficient design. This design allows cooler outside air to get to the air filter. The combination of the heat shield with the fresh air intake tube means that you end up with cooler air going into the engine and better performance. To top everything off, AEM covers these air intake systems with their Limited Lifetime Warranty.
The 41-1003P and 41-1003C air intake systems include a large AEM high flow air filter 21-203DOSK. This washable and reusable air filter uses AEM's Dryflow synthetic filter media, which can go up to 100,000 miles between cleaning. Since the Dryflow media does not use oil this air filter is very easy to clean using AEM's Dry Flow Synthetic air filter cleaner, part 1-1000.
AEM 41-1003P and 41-1003C cold air intake systems fit the following models:
2013 NISSAN ALTIMA COUPE 2.5L
2012 NISSAN ALTIMA 2.5L
2011 NISSAN ALTIMA 2.5L
