This is a complete fuel system upgrade for 2008+ Subaru WRX STI. For the 2015+ cars, this unlocks all the performance the factory turbo can deliver. The kit also mitigates the notorious 2800-3000 rpm hesitation/stumble issue. Note: This kit REQUIRES either the Cobb Stage 3 ECU map, or custom ECU mapping. You MUST have ECU mapping to support this kit.
Fits all 2008-2018 Subaru WRX STI.
