Overview

RennTech packages its most popular upgrades for the 2018-2021 AMG GT R into one matched R1 Performance Package. Each part is calibrated to work with the others on the 4.0L M178 twin-turbo V8. RennTech rates the car at 669 hp and 624 lb-ft with this upgrade. That is a gain of 60 hp and 83 lb-ft.

Key details

The exhaust parts are ceramic coated to control under-hood heat. The GT R package also brings blow-off valve adapters and two high-flow M178 filters, lifting output to 669 hp and 624 lb-ft without hurting daily comfort or reliability.
