Description

Spark Plug Sorted! Your NGK Replacement Guide
> Spark plugs: tiny bits doing a big job in your Dodge RAM or Jeep Grand Cherokee's engine. They spark the bang that makes your wheels go round. Over time, they get worn out by all the heat and tough conditions, especially in those gutsy V8s. That's when you start losing power and burning more gas.
Signs You Need New Spark Plugs
• Engine coughs and splutters, idles rough as guts, and feels like it's lost its mojo.
• Fuel bills are suddenly through the roof; you're spending more time at the pump than you are on the road.
• Engine's a real pain to start, especially when it's cold enough to freeze the balls off a brass monkey.
• That pesky check engine light's lit up on your dash, giving you the evils.
• Plugs look absolutely knackered when you pull them out – burnt, cracked, or just plain sad.
Will it pass WOF?
Dodgy spark plugs can definitely cause a Warrant of Fitness (WOF) fail here in New Zealand if your emissions are too high or it's misfiring like crazy.
DIY or Workshop?
Difficulty: 6/10
Estimated Time: 1-2 hours

🛠️ Bob's "Get It Done Right" Companion Checklist
Before you even think about cracking open the bonnet, a bit of prep work goes a long way. Grab some Brake Cleaner to give those spark plug holes a good blast and get rid of any oily gunk or dusty metal tracks. Safety first, team – chuck on some Safety Glasses to keep stray bits out of your peepers, and a pair of Nitrile Gloves will save your hands from getting covered in grime. A torque wrench is also an excellent investment to ensure proper torque.
Fitment Notes
Make sure you set the spark plug gap just right, as per the vehicle manual. Some models are fussy and need specific types or heat ranges. Always check the service manual for the proper way to do things.

Sorted? Good on ya! – Bob @ CARFIX

🧰 What Else You'll Need:
