While Subarus are known for their relatively straightforward maintenance on components like power steering belts, alternators, and timing belts, spark plug replacement can initially seem daunting. Unlike some vehicles where you can simply remove a coil pack cover and access the plugs, Subarus often require a bit more finesse. However, with the correct tools and techniques, including the essential Car Plug Pop Off Tool, this task becomes significantly easier and more efficient.
One of the Subaru models where spark plug replacement can be particularly challenging is the SG generation Forester XT (models from 2004-2008). Therefore, we’ll use a 2006 Forester as our example to demonstrate how the right approach and tools, especially a quality car plug pop off tool, can simplify this maintenance job.

Time Investment
If this is your first attempt at replacing spark plugs on your Subaru, it’s wise to allocate around two hours for the task. Familiarity and the right tools drastically reduce this time. With extensive experience in Subaru repairs and a well-organized toolset, a seasoned mechanic can often complete this job in under an hour. Factors that can influence the time include the condition of the spark plugs, the accessibility of each plug, and your comfort level working in the engine bay. Using a car plug pop off tool correctly from the start can save significant time by preventing damage and speeding up coil pack removal.
Essential Tools
This spark plug replacement job primarily involves hand tools, although a few power tools can expedite certain steps. We’ll begin with ratchets – a 3/8th-inch drive ratchet is generally sufficient, but a 1/4-inch drive ratchet can be beneficial in tighter spaces. Now, for the star tool that makes this job much smoother: the car plug pop off tool, specifically designed for removing coil packs. While various extensions, wobble extensions, and standard spark plug sockets exist, for this guide, we recommend the Ares 5/8th-inch spark plug socket paired with a 4-inch extension. Complementing this with a 1 and 1/2-inch 3/8th-inch extension proves invaluable, particularly when accessing cylinder number four, which is often the most restricted.
Beyond the specialized car plug pop off tool and spark plug socket, a set of your preferred metric sockets for Subaru vehicles is necessary. This includes 8mm, 10mm, 12mm, and 14mm sockets. Lastly, a set of automotive picks is highly recommended. These picks are incredibly useful for disconnecting the often-stubborn coil pack connectors, making the removal process much less frustrating and preventing damage to the connectors.

By utilizing the correct tools, especially a dedicated car plug pop off tool or a suitable alternative like the Ares spark plug tool, and taking your time, spark plug replacement on your Subaru Forester XT can be a manageable DIY task, saving you time and money while ensuring your engine runs smoothly.
