When should Infiniti FX45 spark plugs be replaced?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Infiniti’s recommendations.

What should I do if I see leaks under my FX45?

Don't ignore puddles of fluid under your Infiniti FX45. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are hard starts and stops bad for my Infiniti FX45 engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

Tune Into Your Infiniti FX45

Is it tune-up time? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, particularly if you want to keep your 2004 Infiniti FX45 in tip-top shape. Periodic tune-ups can bring more power back to your FX45’s engine. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Infiniti, you’re taking vital steps toward keeping your FX45’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Infiniti FX45

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Infiniti FX45 engine tune-up services. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your FX45's filters, specifically replacing the air filter and fuel filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your FX45. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your FX45's mileage and maintenance history can uniquely impact its tune-up needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
