Review on ACDelco D521C Ignition System: Original Equipment for Optimal Performance by Joshua Ford

Revainrating 5 out of 5

Exact replacement of spare parts

If you have 1.4L, just buy it. I paired it with ACDelco 41-121 Iridium spark plugs and it solved all sorts of problems. My engine used to have a terrible idle and now it runs smooth. It also has more initial power. Great part, great result!

Pros
  • Stylish and modern design
Cons
  • Frequency
