HKS 550cc injectors are direct replacement for the factory fuel rail, even the injector harness plugs right in. With any kind of sports turbo upgrade on the SR20 or KA, this is the minimum injector upgrade size that we recommend. Running larger injectors can help to delivery more fuel to the motor when needed under higher HP applications. Even for low HP applications, injectors can be tuned to run lower duty cycle and less chance for injector failure which results from pushing the injector duty cycles too high.
* Injector o-rings are not included.
These injectors will be fine on motors handling up to 300hp on pump gas and 380hp on engines with race fuel. If your car will see semi consistent use of race fuel/track use, its best to go with stronger injectors.
Availability: Usually ships in 5-7 business days.
