Best Spark Plugs For Alfa Romeo 4C

The 4C is the most significant Alfa Romeo of its time. It’s mid-engined and has a carbon fiber chassis that’s almost identical to the one found in the McLaren 675LT. It catapulted this beautiful but perennially underperforming Italian brand into the big leagues with its superb driving dynamics and purity. It also raises some intriguing ethical questions. Alfa claims that the 4C is a junior supercar, yet can it really justify all of the hype when there’s a four-cylinder turbocharged 1.7-liter engine under the hood?
