More affordable option with great performance

Install it on a 2008 F350 with over 450,000 km and the new ignition system will really wake the truck up. Later the truck was sold after the conversion and the next owner is still running without problems. Also, the 3-valve engines they are designed for have an improved head design over 2-valve engines with aluminum heads that tend to spit out plugs. Easy to install and high quality coils along with OEM connectors.

Pros

Ideal for outdoor activities

Cons

Some difficulties
