Upgrade your stock 19lb/hr injectors with these higher flowing injectors. Avaliable in 36lb, 42.5lb, and 60lb, these injectors flow much more fuel per pulse, allowing the injectors to run at a lower duty cycle, allowing them to have a much longer life. We've found that the stock injectors begin showing signs of fatigue around 190whp which would be roughly 238hp at the crank. Fuel starvation can easily cause major engine damage, so don't let it happen to you. In order to run these better-flowing "Bosch style" injectors, custom fuel rail brackets are needed. The kit includes these items as well as the injectors of the size of your choice. 36lb injectors are refurbished used injectors, 42.5's and 60's are brand new. All injector kits come with new o-rings to ensure a good seal.
