Why Choosing Quality Parts Matters: The Impact on Your Vehicle’s Performance

Having a reliable vehicle is essential for most Australians. Your car gets you to work, school, the shops and on weekend adventures. When something goes wrong with your vehicle, you want to get it fixed properly and back on the road as soon as possible. That’s why choosing quality parts matters. Using inferior parts can negatively impact your car’s performance and safety. Read on to understand why you should always opt for high-quality components when maintaining or repairing your vehicle.

The Importance of Quality Parts

After a fender bender or major repair job, you may be tempted to save money by using cheap replacement parts sourced online or from a scrapyard. However, those bargain parts often don’t meet the specifications and tolerances of the original manufacturer components. Low-quality parts can have poorly fitting connections, weaker materials and lack the integrated features designed for optimal performance.

Installing inferior parts can lead to a range of problems including:

  • Reduced engine power and fuel economy
  • Transmission issues like slipping and premature wear
  • Compromised handling and braking ability
  • Excess vibration, noise and leaks
  • Electrical faults and warning lights
  • Faster deterioration of related components
  • Invalidated warranties and insurance claims

When a cheap component fails, it can cause much more expensive damage downstream. Paying for quality parts upfront will save you money and headaches in the long run.

OEM and Aftermarket Parts

When you need new components for your vehicle, you generally have two options – original equipment manufacturer (OEM) parts or aftermarket parts. OEM parts are made by your car’s original manufacturer and are identical to the factory components. Aftermarket parts are produced by third-party companies.

While OEM parts are often more expensive, they consistently provide the highest quality and reliability. The materials, dimensions, seals, coatings and technologies are optimized to integrate seamlessly with your vehicle’s systems. Major manufacturers like Toyota and Ford strictly control their supply chains and manufacturing processes for OEM components.

There is much more variability with aftermarket parts. Some companies produce excellent replacement components that meet or exceed OEM specifications. However, many aftermarket parts use cheaper materials, looser tolerances and lack the original engineering that goes into OEM components. The worst aftermarket parts can be downright dangerous.

When choosing aftermarket parts, go with a reputable brand known for quality. Make sure any warranty provided is comparable to the OEM part warranty. Review feedback and specifications carefully. For critical components like brakes, steering and suspension, OEM parts remain the safest choice.

Key Vehicle Systems to Prioritise

Certain vehicle systems are more sensitive to any drop-off in component quality. It’s worth spending extra for OEM or high-end aftermarket parts for the following critical systems:


Your car’s engine contains precisely engineered components under high pressures and temperatures. Inferior quality spark plugs, pistons, gaskets, seals and hoses are more likely to fail or leak causing performance issues. A damaged belt or timing chain can destroy your engine entirely. Only entrust your engine maintenance and repair to OEM or reputable aftermarket parts.

Emission Controls

Modern vehicles have sophisticated emissions reduction systems. Replacing catalytic converters, oxygen sensors and EVAP canisters with subpar parts will hamper your car’s ability to meet emissions standards. This can cause your vehicle to run poorly and trigger warning lights. Only use replacement emission components that are certified to EPA standards.


Braking is arguably the most safety-critical system on your vehicle. Low-quality pads, callipers, hoses and rotors are more prone to vibration, noise, leaks and reduced stopping power. Invest in premium OEM or aftermarket braking components for confidence and security when braking.

Steering and Suspension

Your steering and suspension keep your tyres firmly planted on the road. Cheap balljoints, control arms, shocks and tie rods wear out faster and are more likely to fail. This negatively impacts steering precision, wheel alignment and handling. Don’t compromise performance and safety – use top-tier parts for steering and suspension repairs.


Faulty wiring, relays, sensors and control modules can cause all sorts of problems, from inconvenient warning lights to complete electrical failure. Electrical gremlins are difficult to diagnose and fix properly. Use OEM-grade parts from specialist auto electrical suppliers when replacing electrical components.
