This is the spark plug and coil pack setup for the Y33 Cima VQ30DET.

• Spark Plugs: NGK 6282
• Coil Packs: Hitachi IGC0015

Notes on install:

• Easy swap — only need to move the BOV out of the way.
• Apply a bit of anti-seize to the plug threads. Hand-tighten, then give it a half-moon turn to snug.
• Add a dab of dielectric grease inside each coil boot.
• Run a short ground wire jumper between coils, with the end tied to the chassis, for confirmed grounding.
