Review on QYL Replacement Avalanche Silverado H6T55171ZC by Carta Gutierrez

Revainrating 5 out of 5

Working, cheap for ignition parts

Some early 2000's GM cars have round coils (more powerful) and some still use square coils. I needed a square and they installed with no problems. After 120,000 miles on my '03 new coils, connectors and cables gave me 20% of my power back.

Pros
  • Replacement parts
Cons
  • Not sure
