This sensor replaces your FK2/FK8 MAF sensor to increase the MAF air metering range from 300 g/s to 500 g/s. With a stock MAF you will reach the maximum range with a stock turbo, airbox and bolt-ons. When this happens the fueling becomes inaccurate.
The Hondata CTR MAF 500 accurately measures 60% more air with the stock airbox, which allows you to tune up to around 640 hp.
Installation involves unplugging the stock sensor and re-using the same two phillips screws to install the new sensor. A FlashPro modification file is provided with this sensor.
A must-have bolt on for the Civic Type R.
