Disappointing Performance from Spark Plugs

I purchased these ignition parts for my automotive, and I'm pretty disappointed with their performance. While the product was easy to install, they provided a very poor spark, which ultimately hindered my car's acceleration and fuel efficiency..

Pros
  • Easy to install.
Cons
  • Poor performance detracted from overall functionality.

Efficient Spark Plugs for Smooth Ride

According to my experience these ignition parts have worked flawlessly in my vehicle, increasing fuel efficiency and delivering a smooth ride... The installation process was easy, and the result was noticeable right away. The only downside is the initial cost, but it's worth every penny in the long run..

Pros
  • Reliable performance and longevity
Cons
  • Pricier than some aftermarket spark plugs

The price is not bad. This customer is paying

They are the correct length because the exhaust manifold on this Chevy is so narrow that correct length is important to me. The price is not bad. This client pays and loves to get things done right. I wouldn't go for the chipped ones because they take longer to install than the average V8.

Pros
  • Same specs as your GM car's original factory component
Cons
  • Almost never
