2004 Infiniti I35 Tune-Up & Engine Service

Enhance Infiniti I35 Performance with a Tune-Up

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you want your 2004 Infiniti I35’s engine to last for a long time. Regular engine tune-ups can optimize your I35’s power on the road. Tune-ups give your engine a boost in efficiency, 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 invest in your I35's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Infiniti I35

The Firestone Complete Auto Care location in your community offers several Infiniti I35 engine tune-up services. The first 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 I35's filters, specifically replacing the air filter and fuel filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your I35’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your I35 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.

Common Engine Tune-Up Q&A For 2004 Infiniti I35s

  • When should Infiniti I35 spark plugs be replaced? Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.
  • What should I do if I see leaks under my I35? Don't ignore puddles of fluid under your Infiniti I35. 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 some driving habits better for my Infiniti I35 engine than others? Hard starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.
