Description

Spark Plug Swap-Out Guide — Starring BOSCH
> Spark plugs are the real MVPs for getting your engine humming, creating that crucial spark to fire up the fuel-air concoction. When they start wearing thin, you'll notice misfires, your fuel economy taking a hit, and overall sluggish performance — especially if you're racking up the kilometres in a daily runner like a Holden Commodore or Ford Mondeo.
What Got You Here, Mate?
• Engine's feeling a bit rough or misfiring
• Suddenly drinking more petrol than usual
• Struggling to get the engine to kick over
• Lost its oomph — not accelerating like it used to
• That pesky 'Check Engine' light has popped on (often pointing to a misfire)
Will it pass WOF?
While dodgy spark plugs won't on their own fail your WOF, the drama they cause — think excessive emissions, engine misfires, or that glowing Check Engine Light — definitely will. Getting those plugs sorted is a no-brainer for a hassle-free WOF pass.
DIY or Workshop?
Difficulty: 4/10 (Can vary depending on engine access)
Estimated Time: 1-3 hours
Tools Required: Spark plug socket wrench, ratchet, torque wrench, spark plug gap tool (if not pre-gapped), dielectric grease, anti-seize compound (optional).
🛠️ Bob's "Get It Done Right" Companion Checklist
Before you dive under the bonnet, a bit of prep goes a long way to make sure the job's not just done, but done safely and cleanly.
• Safety First, Always! Grab some Safety Glasses to protect your peepers from any unexpected grit or grime. And trust me, a good pair of Heavy-Duty Nitrile Gloves will keep your hands way cleaner than a quick scrub at the end.
• Cleanliness is Key: While you're in there, a quick squirt of Brake Cleaner can work wonders for cleaning up any carbon build-up around the spark plug wells before you pull the old ones out. Just remember to let it evaporate before you start the engine!
• Lubrication & Protection: A dab of anti-seize compound on the spark plug threads makes future removal a breeze, and a bit of dielectric grease inside the spark plug boot ensures a good connection and keeps moisture out.

Taking these extra steps will not only make the job easier but also ensure everything goes back together smoothly for a long-lasting fix!
Expert Recommendation
Bob at CARFIX always reckons you should swap out your spark plugs at the manufacturer's suggested intervals, or the moment you spot any signs of wear.

The BOSCH HR7NII332W is a cracker of a choice, renowned for its tough build and consistent performance, making it spot-on for the varied driving conditions Kiwis face, whether you're in a Holden Commodore or a Ford Mondeo.

🧰 What Else You'll Need:
