What It Helps Address

• Rough idle caused by uneven fuel delivery
• Hard starting related to injector performance loss
• Misfire concerns tied to poor spray pattern or flow variation
• Fuel trim issues from inconsistent injector output
• Driveability problems in Chrysler and Dodge multi port fuel injection systems

Installation Notes and Tips

Verify connector style, fuel rail fitment, and engine application before installation. Replace the injector seals and o-rings during service, and inspect the fuel rail and surrounding components for contamination or damage.
