The Hondata CTR MAF 500 sensor replaces your factory Civic Type R MAF (Mass Air Flow) sensor to increase the MAF air metering range from 300 g/s to 500 g/s. With a stock MAF sensor you will reach the maximum range with a stock turbo, airbox, and bolt-ons (after tuning). When this happens, the fueling becomes inaccurate / unstable, which is bad for consistent power and can harm your engine.

When using the stock airbox, the Hondata CTR MAF 500 accurately measures 60% more airflow and allows for tuning all the way up to about 640 horsepower! Installation is very simple: just unplug the stock MAF sensor and re-use the same two Phillips screws to install the new sensor. A FlashPro is required and FlashPro modification info is provided with this CTR MAF 500 sensor.

Use of an aftermarket intake is possible, but we highly recommend using a high-quality intake with laminar airflow. The provided FlashPro modification file will need to be customized and you must ensure the MAF sensor is scaled properly for your aftermarket intake.

A must-have bolt on for any Civic Type R owner serious about making power!
