Toyota GR Yaris – Back to Full Health and Beyond!
This GR Yaris came in for some love and performance upgrades — and we delivered!
Upgrades fitted:
✅ MST V2 intake kit
✅ Whifbitz resonated stainless exhaust system
✅ AIRTEC intercooler
Once everything was installed, we strapped it onto our dyno and were surprised to see just 247bhp, well below the 260bhp we usually see from a standard car.
After a bit of digging, we found the issue — tired ignition components. A fresh set of HKS spark plugs and Toyota ignition coils soon sorted that, bringing power back up to a healthy 268bhp. Much better!
To finish things off, we carried out a custom ECUTek remap, unlocking an impressive 316bhp — transforming this GR Yaris into a proper pocket rocket once again. 🔥
Mods list:
- MST V2 Intake Kit
- Whifbitz Resonated Stainless Exhaust System
- AIRTEC Intercooler
- HKS Spark Plugs
- Toyota Ignition Coils
- ECUTek Custom Remap
Another GR Yaris performing exactly how it should — and then some!
