Here's why:
* Engine Variations: There are many possible variations within the 2.5L engine (different model years, trim levels, etc.).
* Spark Plug Type: The gap specification can change depending on the specific type of spark plug you are using (e.g., platinum, iridium).
How to find the correct spark plug gap:
1. Consult Your Owner's Manual: The most reliable source for this information is your Subaru Outback's owner's manual.
2. Check the Spark Plug Packaging: If you have new spark plugs, the packaging will often specify the recommended gap.
3. Consult a Subaru Dealer or Mechanic: A Subaru dealership or a qualified mechanic can provide you with the correct spark plug gap for your specific vehicle.
Important Note: Always use the recommended spark plug gap. A gap that is too small or too large can negatively impact your engine's performance, fuel efficiency, and emissions.
