The 2016 Soul's 2.0L Nu MPI engine uses long-reach iridium NGK plugs with a precise 1.1 mm gap. The coil-on-plug design requires only basic hand tools, but the rear plug under the intake hose needs a swivel extension.
Spark plug: NGK SILZKR7B11 iridium (pre-gapped 1.1 mm / 0.043 in).
Torque spec: 18 ft-lb — do not exceed 22 ft-lb or risk thread damage in aluminum head.

Socket: 5/8" spark plug socket with 3/8" drive and 6" extension.
Gap check: verify with wire feeler; do not trust 'pre-gapped' label alone.

What the Pros Prefer: 2016 Kia Soul 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.
