2003 Infiniti G35 Engine Tune-Ups & Maintenance

Tune-Ups to Help Your Infiniti G35 Run Better

Is it time for an engine 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 2003 Infiniti G35. Periodic tune-ups can bring more power back to your G35’s engine. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you take your car for regular engine tune-ups as recommended by Infiniti, you invest in your G35's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Infiniti G35

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Infiniti G35 engine tune-up services. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your G35'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 G35. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your G35 can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where Should I Go for My Infiniti G35 Tune-Up?

If you’re looking for 2003 G35 engine tune-up services, head to Firestone Complete Auto Care. Follow Infiniti's recommended maintenance schedule or book an appointment as soon as you notice one of the following: stalling or shaky idling when you’re stopped, diminished fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.

Common Engine Tune-Up Q&A For 2003 Infiniti G35s

  • When should Infiniti G35 spark plugs be replaced? When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.
  • What should I do if I see leaks under my G35? Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.
  • What do hard starts and stops do to my G35 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.
