The 15 Most Frequently Replaced Auto Parts

If you’re a car owner, chances are that there have been times when you needed to replace a part or two. It can be hard to keep track of which parts need to be replaced most often, so we’ve compiled this list of the 15 most commonly replaced auto parts. From spark plugs and oil filters, to brake systems and air filters, we’ll help you stay on top of your car maintenance needs!

1. Air Filters

Air Filters are one of the most frequently replaced auto parts, as they help keep the engine running efficiently and prolong its life. It is recommended to change an air filter every 15,000 to 30,000 miles, or more frequently if you take your car on dusty roads. A replacement air filter can range from $10 to $25 depending on the make, model, and engine of your car. Changing an air filter is a simple task that can be done in less than 15 minutes with no tools required. Also Read, How to change your vehicle oil?

2. Oil Filters

No matter what type or model of vehicle you own, the part you’ll need to replace the most is the oil filter. The full-flow oil filter is the most common type used on cars which is also known as a primary oil filter. It is designed to clean and lubricate the engine by trapping particles, dirt, and debris that can cause damage over time. The recommended mileage to change a car oil filter is every 5,000 to 15,000 miles depending on your make and model. Change a car oil filter more frequently than 15,000 miles if you drive in dusty conditions or use a synthetic blend or fully synthetic motor oils.

3. Spark Plugs

Spark plugs are one of the most frequently replaced auto parts and need to be changed roughly every 30,000 miles. This interval can vary depending on the type of spark plug being used, with basic copper plugs having the shortest lifespan of up to 1 mile. It is important to note that only cars with internal combustion engines require spark plugs, and each cylinder will need one spark plug. AutoZone’s tune-up guide can provide more information on the parts that often need to be replaced during a tune-up, such as spark plugs, plug wires, air filters, and more.

4. Brake Pads

Brake pads are the most frequently replaced component of the brake system, often needing replacement after three to five years or 10,000 to 20,000 miles. Along with rotors, which should be replaced between 50,000 and 70,000 miles, these components are essential for keeping your car’s braking system functioning properly. If you hear a loud squeal or grinding noise coming from your brakes when you apply them, it’s time to bring your car in for an inspection by a certified mechanic. Not all brake pads are created equal, so make sure you use quality products for the best results.

5. Windshield Wipers

Windshield wipers are an important part of vehicle maintenance and are usually one of the most frequently replaced auto parts. Mary Anderson patented the first operational wiper blade in 1903, which still required hand operation to keep the window clean. Windshield wipers should be replaced every year or two as the rubber material that makes up the wiper blades can easily deteriorate due to exposure to different weather conditions. Bosch wiper blades are recommended by most shops, and the Icon is consistently among the highest-rated models. When shopping for Wiper Blades, make sure that you get the right size for your vehicle, as they come in a variety of sizes and shapes.

6. Headlights

Headlights are an important component of any vehicle as they help drivers to see the road ahead, even in the darkest hours. They are one of the components which need to be replaced most often, due to their delicate nature and their exposure to wear and tear. Failing to replace them on a regular basis could lead to decreased visibility and, in some cases, even a car accident. Therefore, it is important for drivers to keep an eye on their headlights and replace them when necessary.

7. Alternators

Alternators are an important component of a vehicle’s electrical system, and they are often one of the most frequently replaced parts. They are responsible for maintaining the correct charging voltage for the battery, and they often last up to seven years or about 100,000 to 150,000 miles. It is important to have the reference of the alternator to find its corresponding replacement parts such as silicon-diode rectifiers, brushes, bearings, and pulleys. 

8. Radiators

Radiators are an important auto part to replace regularly, as they regulate the engine’s temperature. Many auto parts stores and dealerships offer replacement radiators for most newer vehicles. Aftermarket parts are also available, though you will need to provide information about the exact model, year, and make of your car. Searching through our inventory can help you find the right auto radiator for your car. Whether you’re looking for an original or aftermarket part, make sure to check with us first for the best selection and prices available.

9. Fuel Pumps

The fuel pump is an important component of the fuel line, propelling gasoline from the tank into the engine. It is often subject to natural wear and tear and may need to be replaced every now and then. It is important to ensure that the fuel pump is in good condition, as it has a direct impact on the engine and will reduce your vehicle’s fuel efficiency.

10. Mufflers & Exhaust Systems

The muffler and exhaust system are an integral part of maintaining the vehicle’s performance and emissions. Keeping these parts in good condition is essential for optimal performance. A malfunctioning muffler or exhaust system can cause a decrease in fuel efficiency, as well as increase emissions. AQG Auto Wreckers offers a variety of car mufflers and exhaust systems to ensure your vehicle is running at its best.

11. Battery

The 11th most commonly replaced auto part is the car battery. The lifespan of batteries can vary, but typically they will last anywhere from three to five years. Poor maintenance and extreme temperatures can cause a battery to fail prematurely. It’s important to inspect the battery regularly to make sure it’s in good condition and has enough charge. If it’s not, then it’s time for a replacement.

12. Belts & Hoses

Belts and hoses are some of the most common and integral parts of your car’s engine. They provide protection and help with engine performance, so it is important to check these parts regularly and replace them when needed. Serpentine belts should be replaced every 5 years or 50,000 miles, V belts every 3 years or 36,000 miles, and hoses should be inspected at every oil change and replaced as necessary. Aftermarket parts are a great option for replacing these parts as they can provide the same quality and performance as OEM parts at a much lower cost.

13. Suspension Parts

Suspension Parts, such as control arms and ball joints, are some of the most important components in any vehicle’s suspension system. They are responsible for providing a smooth ride and ensuring that the vehicle is able to handle different types of terrain. It’s essential to regularly check these parts and replace them when necessary. Worn-out or damaged parts can lead to excessive wear on other components, resulting in costly repairs.

14. Clutch Discs & Pressure Plates

The clutch assembly consists of a flywheel, pressure plate, and release bearing. This action locks the flywheel, the clutch disc, the pressure plate, and the transmission input shaft together. Every time you press the clutch pedal, the fork engages the pressure plate and the throw-out bearing. The release bearing causes the clutch disk to spin freely, allowing you to change gears without affecting the engine speed. Many replacement clutches come in a kit, with all of the parts you need. The pressure plate has springs that weaken over time, causing the clutch to slip or become difficult to engage. Worn parts should not be reused, since the bearing race may be damaged by wear on the mating parts

15. Control Arms & Ball Joints

The suspension system of a vehicle is composed of several components including control arms and ball joints. Control arms are attached to the chassis and the wheel hub, and they help keep the wheels aligned with the body of the car. Ball joints are used to allow the front wheels to move up and down on the vertical axis. Over time, ball joints can wear out and need to be replaced, so it is important to have them inspected regularly. Many parts houses now offer specialized suspension parts of OE quality in Australia, for the most complete range of vehicle makes and models.
