Give Your Classic a Spark of Life with NGK!
> Alright team, let's talk spark plugs – these little beauties are right at the heart of your engine's combustion. In your trusty classic like a Land Rover 88/109, an early Honda Civic, or a grand old Jaguar Mk VII, these plugs are constantly battling the elements. Over time, those electrodes wear down, the gap gets too wide, and suddenly your engine's not quite firing on all cylinders. That means less power, more fuel, and a generally grumpy engine.
Symptoms That Led You Here
• Engine misfires or rough idle, particularly noticeable at startup
• Noticeably reduced fuel economy on your classic daily driver
• Hesitation or stumbling during acceleration
• Hard starting, especially in cold NZ mornings
• Check engine light illuminated (on vehicles equipped with OBD systems)
• Visible carbon fouling or oil deposits on removed plugs
• Engine running rich with black exhaust smoke
Will it pass WOF?
Spark plugs themselves are not a direct WOF inspection item, however the symptoms of worn plugs—excessive emissions, rough running, and potential catalytic converter damage—can cause WOF failure under emissions testing for applicable vehicles. Classic vehicles pre-dating emissions requirements still benefit from proper ignition for safe, reliable operation on NZ roads.
DIY or Workshop?
Difficulty: 3/10 for most classic engines with accessible plug locations
Estimated time: 30-60 minutes for a full set
Tools required: Spark plug socket (typically 13/16" or 5/8"), ratchet with extension, torque wrench, feeler gauge for gap checking, anti-seize compound, dielectric grease
Classic vehicles like the Land Rover series and early Hondas typically feature straightforward plug access compared to modern engines. The key is ensuring correct gap specification and proper torque to avoid thread damage in aluminium heads.
Expert Recommendation
Bob and the CARFIX team reckon you should swap out your spark plugs at the manufacturer's suggested intervals – usually every 15,000-30,000km for those copper-core plugs in your classic ride. The NGK B6ES is a fantastic choice for these heritage machines; they're built to original specs and have been proving their worth for decades. Whether you're tackling dusty metal tracks in your Land Rover or cruising the coast in your pristine Jaguar Mk VII, good ignition components are a no-brainer for reliable performance.

Fitment Notes
• Verify correct heat range for your specific engine—classics can vary significantly even within model years
• Land Rover 88/109 series (1961-1971) may require different reach plugs depending on head configuration
• Early Honda Civic and Accord models use metric thread specifications
• British classics like the Austin A35, Hillman Minx, and Jaguar Mk VII often specify imperial thread sizes
• Always confirm gap specification against your workshop manual—do not assume factory pre-set gaps are correct for older engines
• Check HT lead condition when replacing plugs on high-mileage classics

🛠️ Bob's Pro Tip: Do the Job Right!
> If you're replacing this spark plug, make sure you've got the right workshop prep, protection, and safety gear ready. Taking a bit of extra time and using the proper safety stands and cleaners makes all the difference for a professional result!
🧰 What Else You'll Need:
• Safety First: Always secure your vehicle on heavy-duty safety jack stands before working underneath. Never rely solely on a hydraulic jack.
• Clean Hands: Keep a pack of Nitrile Gloves handy to protect your skin from grease, oils, and chemical sprays.
• Preparation: Have microfibre towels and a suitable parts cleaner nearby to keep components clean during installation.
