6.0 Premium Stage 6 250CC Injectors (Set of 8) LLY Upgrade for the 6***Must send in cores first or add refundable core charge to your order*** These are a hot street competition injector. They displace 250cc of fuel and we pair these with 75% 100% nozzles. The smaller nozzle will help with fuel atomization and for driving on the street while the larger nozzle would be better for top end power. We do not recommend towing with this injector unless you have very extensive modifications. You will need fuel system upgrades
