If your Subaru isn't running as smoothly as it used to, maybe it's lost some pep, idles a little rough, or your fuel economy has started to drop, it may be time for a Subaru tune up. A proper tune up restores performance, smooths out drivability, and helps your engine stay healthy for the long road ahead.
At East Valley Auto Rebuild in Kent, WA, tune ups aren't an afterthought. Founded by Mark Bryant, the Independent Subaru Guru, and his wife Denise, our family-owned shop has more than 30 years in the automotive industry and 70+ years of combined Subaru experience. From routine tune ups to complete engine rebuilds, we're truly "Your Sensible Dealership Alternative."
Why a Subaru Tune Up Matters
for Your Engine
Over time, normal driving around Kent, Auburn, Renton, Federal Way, Seattle, and Tacoma leaves its mark on your Subaru. Spark plugs wear, filters clog, sensors drift out of spec, and small issues slowly rob your car of power and efficiency.
A quality Subaru tune up service can help:
- Restore lost performance and throttle response
- Smooth out rough idle, hesitation, or minor misfires
- Improve fuel economy and reduce emissions
- Extend the life of ignition and fuel system components
- Prevent bigger problems from developing down the road
Because we specialize in Subarus, and have rebuilt and tuned engines for everything from older BRATs to modern turbo models, we know exactly which components to focus on for your specific year and model. Our philosophy is always to
"keep your vehicle running stronger for longer," and a proper tune up is a key part of that.
What’s Included in a Subaru Tune Up Service
in Kent, WA
We don't believe in one-size-fits-all tune ups. Every
Subaru engine tune up at East Valley Auto Rebuild is tailored to your car's mileage, condition, and service history. Depending on your Subaru, your tune up may include:
Ignition & Fuel System
- Spark plug inspection and replacement with the correct spec plugs
- Ignition coil testing and wiring checks as needed
- Throttle body inspection and cleaning
- Fuel injector cleaning or evaluation as appropriate
Air & Filtration
- Engine air filter inspection and replacement
- Cabin air filter inspection and replacement if needed
- PCV system checks to ensure proper engine ventilation
Fluids & Basic Service Items
- Engine oil and filter service (if due)
- Inspection of coolant, brake fluid, and other fluid levels
- Belt and hose inspection for cracks, wear, or leaks
Performance & Drivability Checks
- Road test to evaluate idle quality, acceleration, and overall drivability
- Scan of engine management system for codes and data irregularities
- Subaru-specific checks based on known patterns for your engine and generation
We'll always explain what we recommend, why it's needed, and what can reasonably wait. There's no mystery, just clear, Subaru-focused tune up service.

See Why Subaru Owners
Keep Coming Back
The quality of work is top notch. Took my 2011 STI there to get the head gaskets done and could not be more pleased with the work they did and how they treated me through the process. Sent photos and videos of the entire process while taking apart the motor. Great people who really do want the best for the customer and their car. Would absolutely take my Subaru there again if needed.
I brought my 2017 wrx with a blown engine to Mark at east valley auto rebuild. I really liked how he took the extra time to discuss all my available options, from keeping it stock to going with more quality parts. Mark covered it all with his extensive knowledge while he tooks us out to lunch. He really made sure that what I wanted out of and from the car is what I got.
I have been coming to this repair shop for a couple of years now and just bought my second Subaru to allow them to keep maintaining my car for me. They have been so helpful to me over the years, always working around my budget, always squeezing me in last minute when they are busy. The owners are great people who genuinely care about their customers and the staff is very informative. Thank you, East Valley!
