  • Direct-fit emission control hardware for service and repair work
  • Supports proper crankcase ventilation sealing
  • Fits many Chevrolet C10, Camaro, Impala, and Corvette applications
  • Also used on GMC C1500, C2500, C3500, and K-series trucks
  • Standard Ignition GV20 for OE-style replacement needs

Compatible With classic Chevrolet and GMC truck platforms as well as Pontiac and Chevrolet passenger cars, including Chevrolet C10, Camaro, Impala, and GMC C3500 applications.

Installation Notes and Tips
