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 Hyundai?
This part (SILZKR7B-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.

Really good pillows
Number of Items: 1, Number of Items: 1
I’ve been using this pillow for a while now and it’s honestly one of the most comfortable pillows I’ve tried. It has a soft, cloud-like feel but still gives enough support for my neck and shoulders. I’m a side sleeper and it keeps its shape well through the night. The material feels high quality, and it doesn’t go flat like cheaper pillows. Definitely improved my sleep quality and worth the purchase.

Soft AND supportive
Number of Items: 1
I knew I needed a very soft pillow - all the foam pillows I had bought recently to try to upgrade our home pilllow selection seemed ok to the touch but were still too firm once I tried them out, but recently I also had some neck pain that needed some gentle support and the old old foam pillow I had that was so very soft was losing its supportive qualities and the pain wasn’t getting better. This one seemed by description to fit the bill- very soft by the company’s own definition but also with support. I’m happy to report this is exactly as advertised- the softest foam pillow I’ve tried out of the box but also good support. Pain has improved since I started using this pillow. I would buy more if we need more pillows, it’s perfect for me and I think would be comfortable for most people. I think you just need to figure out how firm you need your pillow and also height preference . I’m an all over sleeper -back, side, even belly sometimes, so it’s fine for me, but it is a little taller compared to other pillows I’ve bought recently. I didn’t compare/try other prominent pillow brands, mostly my experience is Ikea (my daughter uses a very flat and nice foam pillow from them that is even a little pricier than this one and it works well for her), and whatever brands happen to be available at target and Costco. This price point for a name brand is reasonable, I think; I was looking at other brands way over $100, and I was willing to spend that much for something that would work long term, so this one working was great. Also, this definitely does not have any cooling effect technology, which is fine by me, but something to consider if you do like cool pillows. (Although, PSA: I recently had to throw away older foam pillows that had those cooling gel panels because the gel panels started disintegrating into sticky ooze; gross and had to throw away whole pillow because couldn’t dissociate from rest of the pillow. Sad cuz the foam part of those pillows were fine.) Anyway, if you like softer pillows but want good support, this one works well and is worth trying!!

Flatter than a regular pillow but nice and soft
Number of Items: 1
Is it softer than a typical memory foam pillow? Yes. But it’s also a lot flatter. I don’t find this pillow rebounds very well. It’s good for stomach sleepers but not so much for side sleepers. I’m a 2/3 of the night side sleeper so it’s unfortunately not my magic pillow.

Best pillow for my neck pain.
Number of Items: 1
I've tried so so many pillows to relieve my neck pain at night and this one is the first pillow that has actually worked. I was skeptical at first as this pillow is heavy and dense but one night and I was hooked. I couldn't believe I found a pillow that actually not only was comfortable but also relieved my neck strain. It's worth the cost to now be able to wake up without pain.
