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 Opel?
This part (IKR9J8) 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.

Not very puffy puffy jacket
Size: XX-Large, Color: Denim Blue
At xxl the shoulders fit well and perhaps the first jacket where the sleeves came down to my wrists and not halfway to my elbows if I reached forward. Love the zipper. The zipper pull is at my right hand side. It is where i would use my right hand to engage and pull it closed. The zipper glides smoothly. The hood is voluminous. There is no string available to control the fit of the hood. As it us the hood is much too large. It makes the jacket look cheap and unfinished. The jacket would be immeasura bly better if the was a bit more fill in the body and a string pull in the face of the hood to bring the fit closer.

It's thin but it's good for cooler mornings and windy days
This jacket is not super thick or sherpa/fleece lined. But it's great for cooler temperatures, windy days, or staying warm while out on a boat. It's lightweight, cuts the wind and is great for layering. Folding it into the bag makes it ideal for travel and camping

Okay for the price
Size: XX-Large, Color: Denim Blue
The product was light and compact for packing for an Alaska cruise. It was also sufficiently warm and relatively rain resistant. But on the second day of wearing, the zipper blew out. I was able to fix for a short while, but in the end, I couldn’t use it.

Great deal on a shacket
Color: Khaki, Size: X-Large
The shacket looks like it is depicted in pictures. It is oversized in general since it is intended to be an over garment. The weight of the cotton is heavier than a normal cotton shirt, but not as heavy as a denim jacket. I am 5'8" tall and 175 pounds. My sport coat chest measurement is 44 inches. I ordered XL so it would be large enough to cover a T shirt and shoulder holster for S&W Shield to CCW. I washed in cold and hung dried, and it still feels a little too large. I will try to wash and machine dry and see if the fit improved. The shacket looks to be worn with sleeves extended. I tried rolling up the sleeves and was only able to get two rolls. A third roll was not possible because it wouldn't fit around my forearms even though I'm not muscular. Those wanting to roll up their sleeves may need to alter the shacket. I was pleasantly surprised that the shacket did not have a chemical smell, which makes sense because it is 100% cotton. It instead smelled like cotton. After the first wash I didn't notice any imperfections. The buttons don't seem to be unraveling, and the other stitching looks to be holding. The shacket comes with one extra button. Overall, it looks like a nice shacket. Because it comes from China, I was expecting a stinky, plastic shirt notwithstanding the advertising. But no, it looks like it's all cotton, all quite clean and healthy. For the price, it looks like a great deal. Note that they can't fit all body types. If you're muscular with large arms and shoulders, I would expect the usual difficulty in finding a fit.

Good quality, runs small through middle
Color: Nave Blue, Size: 3X-Large
Good looking shirt and much thicker and sturdier than I expected. Run small in gut though. I'm a 3X in everything but had to get 4X in this.
