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 your vehicle?
This part (CPR8EA9) 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'll stick to Rain Design
Color: Space Gray, Size: mStand, Style: mStand
There are a lot of laptop stands out there and call me a loyalist since I bought my first Rain mStand over 10 years ago but I came back to Rain for my second one after giving the original one to my kid for college. I purchased the Space Gray version to match my current Macbook Pro color. It's still a handsome, well-crafted non-nonsense design. It's great that Rain didn't change the design much from the original one I had. It works well with padding in just the right places, and it's timeless design is a complement to any room decor. Go with Rain.

Simple, hefty configurable small tray
Color: Black, Color: Black
"Hefty" is not an expected description for a drawer organizer. But it is in this case because of the solid metal plate it's made from. You could brain a zombie with this tray and not dent it (the tray... the zombie's the one that would be dented). Guess the material choice does make sense since the two wooden dividers uses magnets to hold positions. A strong bump would be needed to shift the placed dividers. You get some basic configuration choices from the dividers. Including additional (different length) dividers would allow further sectioning options would have been nice. It also looks good too. Like the design and utility. Would also go for a bigger version. Perhaps that one, like this, would have secondary uses... perhaps as armor plating?

Elegant and easy to customize to organize your desk
Color: Black, Color: Black
This desk organizer was higher quality and more elegant looking than I thought it would be, so I decided to use it to hold some things on my dresser. It’s too pretty to hide away in my drawer. The compartments snap into place with magents so you can adjust based on how you want to organize your items. The tray itself is heavy, durable, and well-made. The compartments and edges seem to be authentic wood, and the base surface of the tray is a rubber-like surface that keeps things from slipping while still looking very nice. I like this tray enough to put it on display as a part of my home decor. It’s not only useful for organizing some odds and ends, but is also very beautiful and well made.

Stylish Aesthetic with Functional Limitations
Color: Black
This desk organizer offers a sophisticated look that complements modern furniture and decor quite well. The combination of aluminum and walnut creates a professional appearance that effectively tidies up a workspace or nightstand. I particularly appreciate the soft-touch base, which provides a safe surface for delicate items like phone screens or watches, ensuring they remain free of scratches. Additionally, the materials are very easy to wipe down and maintain. However, the build quality does not entirely justify the premium price point. The aluminum components feel more like thin, shaped sheet metal rather than a solid, high-end material. While the walnut accents are a nice touch, they lack the weight and substance I expected for a valet tray in this category. The primary functional drawback lies in the magnetic adjustment system. The magnets are relatively weak, meaning that accidentally bumping a divider while reaching for an item can easily shift the layout. This requires frequent readjustments, which can be frustrating during a busy workday. Furthermore, the magnetic rails can interfere with other metallic or magnetic objects you might try to store. If you are looking for a purely aesthetic upgrade to organize lightweight items, this tray serves that purpose, but it falls short in terms of stability and material density.

Love the customizable dividers
Color: Black, Color: Black
I really like this desk drawer organizer tray. It comes with two removable adjustable dividers that are magnetic. They have a strong magnetic pull and stay in place and do not move or shift at all. I love the overall look of it. It’s very sophisticated looking. It can be suitable for a man or a woman. If it’s into my drawer perfectly and I love the smooth modern design of it.
