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 (20,8 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 your vehicle?
This part (BU8H) 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.

My dogs love fetching this toy, then fighting over who’s going to bring it back to me
Both of my miniature dachshunds took to this tug of war toy immediately after opening it. I liked the fact it didn’t smell terrible like most of the scented dog toys I’ve purchased in the past. Instead this one actually smells good, it’s sweet and fruity smelling. It’s extremely durable and very heavy duty. The only problem is that it’s pretty thick and heavy, especially for my small dogs. They still like playing fetch with it, then fighting over which one gets to bring it back to me. It really would have been the perfect fetching toy for them, if only it had been a little bit smaller and lighter. If you have larger sized dogs who enjoy playing fetch and tug a war, I’d recommend giving it a try.

Good Quality Toy, but Not a Hit with My Dogs
I am a bit unsure about this toy. Unfortunately, my dogs do not seem to enjoy it very much. I thought the blueberry apple scent would make it more appealing, but they tend to lose interest almost as quickly as they start playing with it. I was hoping this would be something we could use for games like tug of war, but it just has not held their attention. That said, I may just have picky dogs, so this could be a different experience for others. The reason I gave it two stars instead of one is because the quality is actually quite nice. It feels well made and has a good overall design. However, I would be a little cautious giving it to aggressive chewers, as it seems a bit on the softer side. For dogs that are more gentle with their toys, it would likely be a better fit. The size is also great, and it has a lot of potential. It just has not gotten much use in our house, likely due to my dogs not being fans of the flavor. Overall, if you have picky pups like mine, this may not be the best choice. But for less selective or gentler dogs, it could still be a solid option

Stretchy, but Smaller & Softer Than Expected; Berry Fragrance Dominates; May be Best 4 Puppies
I was directed to read guidelines that were on the internet, prior to use. I was not expecting that and that was a big turn-off. Basically, it's all about liability, this product has the possibility of being torn apart and I am basically warned that if a piece is chewed off, that's bigger than a grain of rice, to toss, this. I was repeatedly reminded, again and again, and again that pet safety was my responsibility. Yeah, I know that. All these suggestions and warnings should have been made clearer in the listing. Is this built to flex? Yes. Does it bend? Yes. Does it stretch? Yes. Is this rugged? That's open to debate, based on the users, for a puppy, to some degree, but their teeth are very sharp. Is this soft on teeth? I don't disagree. Does this have a durable design? Depends on the user. Floats in water? I do not doubt it. Does this have an enticing scent? For a human, yes, for a pet? Depends if your pet loves berries. This is no pigs ear/bone, so, chewing is not a natural draw that I saw, which I think may be better, because this is soft and easier to tear to pieces than expected. To motivate the first time, I found it best to initiate the tug of war, but this is smaller than I envisioned too, causing me to have to bend considerably to participate. A tennis ball in a tube sock is longer. A two-dog tug of war works best with this. Nevertheless, it's a better toy than teaching pooch to have a battle using clothing, avoiding future attractions to my socks. There is some flexibility to this. Durability is an issue. I think this would have been more interesting if it had been made out of rawhide. It does have a comfortable grip, for a human, but the toy pays a price for that with what I would consider fragility. The berry fragrance dominates, it's nice for a human, but sorry, it ain't no bacon aroma. It's like a thick heavy rubber hose. Value? In hindsight, I just do not see the value I was expecting. I mean really, a grain of rice warning not to use. Durability at issue in my eyes. Country of origin? Vietnam. Is this perfect? Not in my opinion. Rating? A strong three (3) stars at best in my eyes. This is not for a tough chewer. I have to constantly monitor its condition. It does succeed as a tug toy, but it has more limitations that I was expecting. I hope my thoughts added a bit of information.

Bully proof?!
Size: 5 in
We have the cutest little pit/lab mix who destroys stuffed toys in about two seconds flat. It’s always a HUNT to find toys he won’t instantly shred. This brand has some of the best! They were in FiveBelow for a while and it was the only brand that stood up to him initially. He finally got through the first only after MONTHS so we bought a few back ups and they’re still going strong months later! They’re also not super heavy so these end up being the toys we play fetch with most often! 100% will be buying more in this line in the future!
