2004 Infiniti FX35 Tune-Up & Engine Service

Enhance Infiniti FX35 Performance with a Tune-Up

Is your engine overdue for a tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, especially if you drive a 2004 Infiniti FX35. Routine engine tune-ups can bring power back to your FX35. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Infiniti for your vehicle’s tune-up schedule, you can rest assured you’re investing in your FX35’s long-term engine performance.

Routine Engine Tune-Up Service for Your Infiniti FX35

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2004 Infiniti FX35. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your FX35'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 FX35. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your FX35's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Common Engine Tune-Up Q&A For 2004 Infiniti FX35s

  • Will it hurt my Infiniti FX35 to drive with old spark plugs? 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 does a puddle underneath my Infiniti FX35 mean? Don't ignore puddles of fluid under your Infiniti FX35. 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 FX35 engine? Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.
