• Stainless-steel calibration slide and spring assembly prevents corrosion within the fuel control body, which leads to an extended service life
• Precision-wound and precision-trimmed solenoid windings allow the computer to command efficient delivery of fuel
• High-temp Viton® O-rings enable prolonged sealing of injector under extreme heat conditions
• Fiber-optic yttrium aluminum garnet "YAG" laser welding and 100 million cycle testing ensure quality in every box

• Check Engine Light/Misfiring engine caused by a change in the injector's flow
• Noticeable fuel odor caused by leaky injector
• Reduced gas mileage caused by an incorrect injector spray pattern
• Inconsistent engine idling, hesitation or stalling caused by dirty injectors
• Use Fuel System Cleaner to prevent carbon from building up on your fuel injectors
• Always replace the Fuel Pump Strainer or Fuel Filter, where applicable, to prevent debris from clogging injectors

If an injector is faulty on a vehicle with high mileage, the remaining injectors are likely in a similar condition, or will be in the near future. Replacing your injectors as a set ensures each cylinder is receiving the same amount of fuel, leading to better performance and improved fuel economy. Since the time required to replace a single injector is about the same as replacing all the injectors, manufacturers always recommend replacing them as a set.
