Understanding Engine Tune-Up Services at Sunland Tire
In the past, engine tune-ups were more labor-intensive, requiring the inspection of numerous components such as the distributor, cap, rotor, ignition contact points, condensers, and carburetors. Today, many of these checks are no longer necessary due to modern vehicles’ electronic control units (ECU), which now regulate engine timing. While the process has become simpler, regular engine tune-ups are still essential. A tune-up today typically involves inspecting components like spark plugs, spark plug wires, oil and oil filters, and fuel filters. Routine tune-ups ensure that your engine runs smoothly and efficiently, helping to prevent breakdowns and extending the life of your vehicle. A well-maintained engine also ensures optimal performance, which is why regular tune-ups are crucial.

Why Choose Sunland Tire for Engine Tune-Up Services?
During an engine tune-up, our technicians will inspect your spark plugs, which ignite the air and fuel mixture needed for engine operation. We’ll also check the spark plug wires, which transfer voltage from the spark plugs—worn wires can cause misfires. We will assess the condition of your fuel filters, which block debris from reaching the engine. A clogged fuel filter can lead to sluggish acceleration and poor engine performance. Additionally, we will examine the air filter, which prevents debris from entering the combustion chamber. Blocked airflow can cause the engine to work harder, reducing horsepower. Our team will ensure that these components, along with others, are functioning at their best. Follow your vehicle’s owner’s manual for recommended service intervals, and contact us when it’s time for your next engine tune-up.
