ACDelco 748B Original Equipment Spark Review

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..

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..

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.
