  Q: How do you replace spark plugs, and what tools and procedures are required on Nissan Maxima?

  A: On 2000 and later models, checking and adjusting the spark plug gap is no longer necessary. Spark plug replacement requires a spark plug socket that fits onto a ratchet handle, lined with a rubber grommet to protect the porcelain insulator and hold the plug during insertion. A wire-type feeler gauge is needed to check and adjust the spark plug gap, along with a torque wrench for tightening the new plugs to the specified torque. When replacing plugs, purchase the correct ones for your vehicle, adjusting them to the proper gap before replacing each plug individually. Inspect new plugs for defects, ensuring there are no cracks in the porcelain insulator. Check the electrode gaps using the wire gauge, adjusting as necessary with the notched adjuster on the feeler gauge. For removal, work on one spark plug at a time to avoid mixing up wires, removing the wire and boot by grasping the boot and pulling straight up. Clear any dirt from the spark plug area with compressed air or a bicycle pump before removing the spark plug. Compare old plugs with new ones to assess the engine's running condition. Before installation, apply a thin coat of anti-seize compound to the plug threads and use a snug-fitting rubber hose to help align the plug with the hole, preventing cross-threading. Tighten the plug to the specified torque and attach the plug wire using a twisting motion for older models, while newer models require pushing the assembly straight down onto the plug. Repeat the procedure for the remaining spark plugs, replacing them one at a time to avoid confusion.
