keep in mind these are mitsubishi motors colors hyundais may vary but i have not seen that yet
also just becuse you swap these injectors into your car it doesnt mean you will gain anything
some of the cars you can get the mass airflow sensor and swap it in with the injectors
if anyone has any variations please post them for all of us to see
