Fitment Notes

  • Always match heat range, thread size and electrode design before ordering. Verify VIN/engine.

Important: Spark plugs are not returnable, exchangeable, or refundable once fitted. Confirm you are ordering the correct part for your vehicle. Compare the new spark plug to the removed plug for thread reach, thread diameter, hex size, electrode style, gap specification, and heat range before fitting. Mismatched spark plugs can cause misfires, pre-ignition, detonation, fouling, or engine damage.

Returns Notice: Once a spark plug has been fitted or threaded into a cylinder head, it cannot be returned, exchanged, or refunded under any circumstances.

Installation / Use / Maintenance Tips

  • Allow the engine to cool fully before removal - cylinder heads are easily damaged when warm.
  • Use the correct deep-socket plug spanner (16 mm) and avoid impact tools.
  • Inspect the existing plug for fouling, oil contamination, or worn electrodes - may indicate engine condition issues.
  • Verify the gap if your supplied plug is not factory-set; consult your service manual for the correct value.
  • Apply a small amount of anti-seize to the threads (sparingly) and torque to manufacturer specification.

Common Questions

Will this NGK spark plug fit my Jeep?
This part (ZFR5A-11) is listed for the applications shown on this page. Always confirm the correct heat range, thread size and electrode design against your vehicle's service manual or a parts lookup before ordering. Verify VIN/engine.

What does the NGK part code mean?
The NGK trade number encodes physical and performance characteristics - thread/reach, electrode design, heat rating, and projection. Each digit and letter has meaning in NGK's naming convention. The heat range is usually the standalone digit (e.g. BPR6ES is heat range 6).

What is the difference between this NGK plug and a Bosch / Champion / Denso equivalent?
The cross-references listed under OEM Reference Numbers are functionally equivalent for the same applications, but materials, electrode design and heat dissipation can differ slightly. NGK is OEM-supply quality and most manufacturers specify NGK or Denso as their factory plug.

How do I confirm fitment if my engine variant isn't listed?
Match the supplied thread size, reach, electrode design and heat range against your existing plug. If unsure, request fitment assistance before ordering.

I like this brush
Style: Medium Dog, Size: 1 Count (Pack of 1)
I'd used the thumb brush, the slanted brush and a human soft-bristled toothbrush on my dog over the course of four years. I hate those thumb silicone brushes because my fingers are slim so it slides everywhere. The slanted one is cool. But I got so used to being able to use this collection of human soft-bristled toothbrushes that I'd gotten from the dentist. This one felt weird at first. My dog didn't really understand what I was putting in her mouth and jerked back. We'd gotten a system down for how far back to go so I wasn't knocking her gums and held her jaw out to see her teeth. It's weird not having to do that anymore. I like the brush now. It's a little pricier than other dog toothbrushes. I think if I hadn't used human toothbrushes (and gotten so many compliments from dog vets who didn't know that was what I was using), I would've started off with this one. I'll probably use it again after the three months. Not sure yet.

Low cost buy to put off big costs later
Style: Big Dog, Size: 1 Count (Pack of 1)
These came recommended to us by our veterinary dentist. The bristles are soft and hold up great even with daily use on multiple dogs (they each now have their own toothbrush). It definitely doesn’t beat a yearly cleaning, but it helps prevent oral issues.

The best toothbrush, and I've tried them all!
Style: Small Dog, Size: 1 Count (Pack of 1)
I have a little 4 year old Maltese and Shih Tzu mix. She has very tiny teeth that are already starting to show signs of dental disease. I know it's important that they get brushed because small breed dogs are more prone to dental and gum problems. But I've tried every little toothbrush out there and it's a battle trying to brush her teeth. And unfortunately she usually wins! This brush is the best. It is soft and round and she completely tolerates it. I put a little doggie toothpaste on it, which she likes the taste of, and I'm finally able to at least move the brush and paste around her gum line. She still fights me a bit, but nothing like she used to. I would highly suggest that you give this toothbrush a try.

Flimsy and snapped easily
Style: Big Dog, Size: 1 Count (Pack of 1)
Snapped in literally under a minute of using it. The toothbrush head is so small and the handle is really thin and flimsy even though it’s advertised for large dogs… I’m so disappointed.

does the job
Style: Medium Dog, Size: 1 Count (Pack of 1)
Its does the job of cleaning my dachshunds teeth. The only issue is that the SMALL and MEDIUM are the same size. Small was okay but wanted something that would cover more area. Picked up the Medium and they are basicly if not the same size....
