The Subaru WRX and STI have one of the most passionate enthusiast communities in the US. From autocross and rallycross to track days and dyno competitions, WRX and STI owners push their cars constantly. A mileage blocker keeps event miles separate from road miles — protecting resale value on one of the most depreciation-sensitive performance cars in America.
Compatible Subaru Models

The WRX Tuning Community
The EJ and FA engine families are among the most heavily tuned in America. Dyno pulls, Stage 2 tunes, open deck builds — every one adds odometer miles. A Subaru WRX mileage blocker stops that during testing sessions.
