Customer Feedback

After installing the G42-1200 on my 2019 Mustang GT, the difference was night and day. The turbo spooled quickly, and I was able to hit full boost much sooner than with my old setup. My buddy who has a 2021 Civic Type R also made the switch, and he couldn't believe how much power he gained while still maintaining daily drivability.

Note

Alternate coolant and oil fittings and flanges are available, so make sure to check compatibility with your specific setup.
