2010 Mazda 3 2.5L AEM Cold Air Intake Kit

The new 2010 Mazda 3 2.5L with manual transmission is proving to be quite a popular compact model. It provides great power, handling and fuel mileage. AEM sought a way to make this compact speedster even more powerful by developing a specially designed AEM Cold Air Intake System with either gunmetal gray or polished aluminum intake tube finishes. Product number 21-695C (Gunmetal Gray), and 21-695P (Polished).

“The development of a true cold air induction system for the 2010 Mazda 3 was approached by keeping the overall design and installation of the system simple while still enabling it to perform significantly better than the stock intake,” says product design manager John Concialdi. He also explained that the intake itself is simple for the end user to install in part due to the development of a special throttle body coupler which allows use of the OEM PCV hard line. The intake itself was developed with 2.75″ diameter tubing that goes to a cone shaped air filter with an offset flange. This allows placement of the filter in a low isolated location behind the front fascia so it feeds cooler outside air to the engine. AEM’s R&D group tested several different Venturi sizes until the right one was found to satisfy their demands for proper fuel trims and power output.

The 21-695C and 21-695P intakes performed strongly during testing showing a gain of 6.7 hp at 6100 rpm and 5.75 ft-lbs of torque at 6100 rpm. This kind of performance gain along with an easily cleaned non-oiled filter create a simple yet powerful upgrade for your new 2010 Mazda 3 2.5L with manual transmission. AEM has been pioneering well engineered Cold Air Induction systems since 1994 and the 21-695C and 21-695P are no exception to AEM’s strive for great performance and precision engineering.
