The Industrial Injection 20% over R1 Injectors have been extrude honed and balanced to a perfect matching set injectors that flow 23LPM. The R1 20% over injectors can be run with a stock turbo, but an upgraded turbo or compound turbo setup is highly recommended to help reduce EGTs. We typically see a 1-3MPG increase in fuel economy. The injectors are balanced to a tighter tolerance than the original manufacturer and a lot of time is put into making these the best injectors money can buy. All the injectors are built in house with built with BRAND NEW Factory OEM parts including the nozzles.
