A worthy upgrade

This is a great upgrade from the 350, the car now feels how it should, 375 is the sweet spot for these cars.

Excellent service again, update is very easy to install and the mr375 is a massive improvement to the mr350 I was running. There’s no turbo lagg now and the torque is much higher right from low rpm highly recommend

Quality product less than 10 minutes to install, the car was already mp350 but this takes the torque to another level.
