What the Pros Prefer: 2025 Honda Hrv Spark Plug Workflow
Precision plug replacement, coil boot protection, and aluminum head safety.
Debris Clearance & Coil Pack Removal
Shop Tip:Blow compressed air around ignition coil boots before removing them. Road sand and gravel trapped in the spark plug wells will fall directly into open cylinders if not blown clear first.
Magnetic Spark Plug Extraction
Shop Tip:Use a magnetic plug socket with built-in swivel. The magnet prevents dropping the plug down the long well, which bends the electrode gap shut on impact.
Electrode Gap Verification
Shop Tip:Check gap against OEM factory spec using gentle wire-loop gauges. If adjustment is required, gently bend the ground strap without touching the center porcelain.
Hand-Threading & Torque Wrench Tightening
Shop Tip:Hand-spin the extension bar by hand until the plug seats against cylinder head. Torque to factory specification—never guess on soft aluminum cylinder threads.
