2020 Subaru WRX STI Engine Tune-Ups & Maintenance

Tune Into Your Subaru WRX STI

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, particularly if you want to keep your 2020 Subaru WRX STI in tip-top shape. Regular engine tune-ups can optimize your WRX STI’s power on the road. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Subaru's recommendations, you invest in your WRX STI's long-term health and engine performance.

Subaru WRX STI Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2020 Subaru WRX STI. 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*. Another service option pays special attention to the filters in your WRX STI. Specifically, we replace the fuel filter and air 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 WRX STI. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your WRX STI 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 Subaru WRX STI Tune-Up?

Schedule your next 2020 WRX STI engine tune-up service at Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Subaru’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: decreased gas mileage, "rough" idling or stalling when stopped, knocking noises in the engine, or a lit up check engine light on your dashboard.

Common Engine Tune-Up Q&A For 2020 Subaru WRX STIs

  • What happens if my Subaru WRX STI spark plugs fail? 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 do I do if I see a pool of liquid under my Subaru WRX STI? Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.
  • What do hard starts and stops do to my WRX STI 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.
