AEM 21-814C Cold Air Intake Adds Horsepower and Torque to 2017 Toyota Corolla 1.8L
- Sep 7, 2017
While officially code named the 2ZR-FAE, the engine is typically referred to simply as the 2ZR. It’s manufactured at Toyota’s engine plant in Virginia and has been in production since 2007. Both the engine block and the cylinder heads are cast from aluminum alloy with DOHC and 16 valves with dual variable valve timing with intelligence (VVT-i). In stock form, the 2ZR produces 132 horsepower at 6000 RPM, and 128 lb-ft of torque at 4400 rpm. These figures come from tests of the engine not installed in a vehicle, so it’s representative of engine power at the flywheel. When measured at the drive wheels, with the transmission and drive train consuming power, the horsepower could be as much as 20 percent lower. In order to raise horsepower and torque, the engineers at AEM analyzed the layout of the air intake system on the 2017 Toyota Corolla and recognized there was a route to more power. Not to take anything away from Toyota engineers, but their responsibilities in creating an intake include variables like cost down to the penny and how many seconds it takes a worker to install the intake.
The solution arrived at by AEM is a unique system designed, tuned, and dyno-tested to fit specific Toyota Corolla models. The 21-814C cold air intake system relocates the air filter low and towards the front of the car where it’s exposed to cooler air, and away from high underhood temperatures. The cooler air is then channeled through a gunmetal-gray mandrel-bent aluminum intake tube directly into the throttle body. The factory PCV and MAF sensor mount directly on the intake tube, connected by a provided extension harness. AEM Dryflow filters use an innovative high-performance synthetic filter material. The large oval 21-2127DK AEM DryFlow filter is formed from a washable, non-woven synthetic filter medium optimized for airflow and performance with sacrificing filtration. Dryflow filters are so efficient that they capture up to 99% of all contaminants before they can harm your engine. The AEM 21-814C cold air intake is a relatively straightforward DIY modification that takes just a few hours to install, even for someone with little mechanical experience. Tools required are those that just about everyone has in their garage. The AEM 21-814C utilizes only the factory mounting locations, so there are no holes to drill or permanent modifications to make.
