Kit includes: JWR60 map, air filter, intercooler, exhaust
Kit provides: +60 bhp
This stage requires an uprated intercooler and turbo-back exhaust system as well as a higher flowing air filter.
The added hardware parts help ensure a solid 50-60 bhp increase over standard, and the exhaust system will at the same time provide a fantastic sound no matter what brand you choose for your car.
A higher flowing air filter is not a strict requirement but still recommended, and as a bonus it adds a little more induction noise depending on which brand you go for. Especially the K&N X-Stream filter will add more induction noise due to its open-ended design.
