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. We balance the injectors to a tighter tolerance than the original manufacturer and have put a lot of time into making these the best injectors money can buy. All the injectors we build in house are built with BRAND NEW Factory OEM parts including the nozzles.
