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 (CR9EK) 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.

Doesn’t leak, durable, keeps drinks cold
Color: Sparkling Sherbet, Size: 40 Ounces
Absolutely love this water bottle. I am a water bottle junkie and this one is my favorite. It doesn’t leak and the fact that I can guzzle or sip through a straw is a major plus. It is kind of heavy but it is a big thermos. The only reason I didn’t give five stars is because the bottom doesn’t fit in all cup holder. It keeps my drinks cold all day and is super easy to clean. It is very sturdy and well made. I figured after using for a while, the lid wouldn’t pop open as easy as it did when it was new, but it still does. I also love the lock feature incase the button accidentally gets pressed when I am carrying it around in my bag.

Compact, incredibly absorbent, and a travel essential.
Color: Gray, Size: 48.00" x 24.00"
The Rainleaf microfiber towel has been a fantastic addition to my gear. It’s remarkably compact and lightweight, which makes it perfect for tossing into a gym bag or packing for trips without taking up unnecessary space. Despite its size, it’s surprisingly super absorbent and dries much faster than a standard cotton towel, which is a huge plus when you're on the move. It’s well-made, feels durable, and is definitely a must-have for anyone who travels, camps, or hits the gym regularly.

Great Travel Towel !!
Color: Mint Color, Size: 72.00" x 40.00"
I travel for work. The last few years I've noticed the quality of hotel towels has gone downhill. I suspect that they are not replacing them as often to save money. So not only are hotel towels too small, they are thread bare, thin and scratchy. So I thought about bringing my own towel, but, it's not practical as they are heavy and bulky to pack, and they take a long time to dry. This Rainleaf Microfiber towel is the answer to my prayers. I bought the big one, 70 X 40. I tested it at home. It is kinda strange to dry off with it because it's different. Not bad, just different. It smooth but not soft and fuzzy like a cotton towel. BUT, it dries amazingly well. It doesn't even get that wet. It's more like patting dry then rubbing you dry, it you know what I mean. Once you get used to it, it works great. Even though is it huge at 70" X 40", it weighs less than 1 pound. Super small and great for packing. Corner pocket would be good at the beach for keeping valuables out of sight. It's my new go-to hotel towel. I may even bring it on my cruise !

Dries quickly and very portable
Color: Violet, Size: 72.00" x 40.00"
Dries you off quickly, is light weight, and very portable. I bought this to use for the gym, where we’ve been having to shower (instead of at home) as our water heater has gone out. Until we get it replaced we’ve been having to use the shower at the gym after our workout. I wanted a towel that would also be good for taking to the pool when I lap swim. This fits the bill. It dried me super quickly (less than 1 min I was fully dry). It didn’t weigh the towel down either. I got the extra large one, and I am 5’6” and it was plenty big to wrap around me while I was walking around to get dressed. It’s super easy to tie using the corners and it will stay put on you. I really like this. I will likely buy a few more in smaller sizes to use for hair, kids, pets, etc. it’s really good for the gym, showering on the go, and the pool so you can dry faster. I plan on using the smaller ones also for taking on a run in the hot Florida summer to keep the sweat from dripping. It doesn’t seem to have an odor, and time will tell if the towel’s silver ion feature works well, but this was worth the price in my mind.

Very compact, yet absorbent
Color: Navy Blue, Size: 48.00" x 24.00"
This is a unique kind of towel that has very little volume and rolls up to a tiny size. It would be great for a camping trip, or any situation where size is important. It's also surprisingly absorbent, considering how thin it is. I use it for toweling off after taking a shower at the gym. I should also mention that it dries very quickly. The only thing I don't like about it is that it is kind of "sticky" when you're running it across your body. That takes some getting used to.
