Review on Ignition Coils Cadillac Buick Lucerne by Derrick Bellando

My dad has had the same coil packs on his STS-V since the car was new (they have 164,000 miles on them now). It took us an evening to remove the old packages and install these. Once the car was closed, it started with no problems. Now the car is quieter and smoother than before. My father now claims his car runs better than new. I waited a few weeks to check as I wanted to make sure the coil packs weren't having any issues. Seriously, not only is this a good original or better quality product, we saved almost $1,000 on the parts alone. Many Thanks.
