The system has changed drastically over the years, where newer ignition systems require only spark plugs and wires/coil boots to be changed at a certain mileage. The ignition system consists of spark plugs, plug wires, coils, and other electrical components that ignite the air/fuel mixture in your combustion chamber. It’s also a great time to check other components under the hood such as belts, hoses, and fluids.

Today, the vehicle’s engine computer and engine components constantly keep these systems running right where they should. As electronic ignition replaced points-style systems, the need was still there for plugs, cap, rotor, and carb adjustments, but ultimately, even that became extinct once DIS (distributorless) ignition systems and computer-based fuel injection became the norm. With vehicles of old, this was a regular occurrence. The process was as intricate as tuning a musical instrument – ignition and fueling had to work in perfect tune with each other for optimal performance, thus the term. For over 50 years, a tune-up meant that the vehicle’s ignition system – breaker points and condenser, were replaced and/or adjusted, a new distributor cap, rotor, and spark plugs were installed, ignition timing was set, and the vehicles carburetor was adjusted and “tuned” (hence the term) for optimal performance. Inspect the coolant, radiator hoses, HVAC system, brake pads and all suspension components.The term “tune-up” has drastically changed since the phrase was coined during the dawn of automobiles. Every 30,000 miles, replace the air filter and power steering fluid. Most 25,000-mile maintenance service requires replacing the fuel filter. Every 20,000 miles inspect the battery and coolant.

Furthermore, inspection of the transmission fluid level, coolant, power steering fluid, windshield washer fluid and wipers, tires and all exterior lights is also encouraged.
