What happens if my Infiniti M35 spark plugs fail?

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 M35 mean?

Don't ignore puddles of fluid under your Infiniti M35. 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.

What do hard starts and stops do to my M35 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.

Tune-Ups to Help Your Infiniti M35 Run Better

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, especially if you drive a 2009 Infiniti M35. Periodic tune-ups can bring more power back to your M35’s engine. 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 M35's long-term health and engine performance.

Infiniti M35 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Infiniti M35 engine tune-up services. One option 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*. Another service option pays special attention to the filters in your M35. Specifically, we replace the fuel filter and air 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 M35’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your M35: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
