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 Smart?
This part (LKR8A) 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.

Rejuvenates your Robovac, but one caution
I was a little wary buying third-party aftermarket parts for my Eufy Robovac 30c, however, all the parts in this kit are virtually identical to OEM parts. I replaced all three brushes and all three filters and let it loose on my Golden Retriever-inhabited living room. I can honestly say the result was a 50% increase in the amount of fur collected. I suspect that over time there is a loss of performance so gradual that it's easy to not notice. I assume the new filters returned the vacuum power to it's original level of suction was a big factor. When I was browsing through all the available choices here on Amazon, a plastic "ring" kept appearing in many of the product images, however, people did not know what it is for or simply did not get one in their shipment. If you look at the photos I've attached one can see that I did indeed get one and figured out its purpose, to remove fur and/or hair from the horizontal brush. The bottom line is that I would definitely buy this item again. =========== EDIT, four weeks later: Since replacing the main roller brush with the one included with this product, I have experienced several “Roller brush is stuck” shutdowns and alerts. In each case, there has been nothing tangled in the brush and the brush was free to spin. I have to say it’s quite annoying to come home expecting the floor to be cleaned but only to find this error long before the job was finished. Today it gave this error twice in one cleaning cycle. I never experienced this problem with the OEM roller brush.

Euphy works good as new!
Style: 19 Pack
As soon as I opened the package everything looked the same- pre-filters, filters, main brush, and side brushes. I changed the big brush first;the only issue was the new brush body didn't have the white arrows to help aligning but that didn't affect how the brush worked. I changed filter and pre-filter, and finally the side brushes. When I turned on my "Goophy" and tried to let her run the side brushes were a little too (Goophy's side brushes sounded a little louder). I trimmed the side brushes a little and all was well. Goophy didn't want to run herself but it didn't take long for me to figure out it wasn't the new brushes ;just the operator pushing the wrong button. My Goophy Euphy did what she was supposed to do- vacuum the carpet and tile floor. Goophy Euphy still wanted to take the long way to her charging station which was nothing new and easily corrected. Over all the new brushes and filter restored Goophy Euphy back to when we first used her!

Don't be cheap like me - buy these and save yourself the hassle!
Style: 19 Pack
I made the mistake of going with another, slightly cheaper set of replacement parts for our Eufy RoboVac 11S. I did not heed the cautionary tales which lead me having to find replacement parts for the replacement parts. This brand fits our vacuum perfectly - the corner brushes don't pop off, the filter is the right size and the roller brush gets sufficiently tangled with cat hair so clearly also a good fit. My only concern (and why I only gave four stars) is - surprise! - the corner brushes. Do they stay on? YES! In fact, they is so secure, I had difficulty swapping one out. Here's the peculiarity of the brand - the "whiskers" on the spinner fell out. I found them all over the floor, on different surface types and under various conditions; they were not getting caught on any one thing. Not all at once, but over two or three uses, one of the corner brushes had become devoid of almost two entire spokes! Ironically, the little guy can't seem to pick up his own mess but I digress. Without the whiskers to grasp, removing the part was difficult. I ended up using a small flathead screwdriver for leverage to pop it off. While the other corner brush appeared to have shed some whiskers as well, it was not in need of replacement. Despite the shedding, this will be my first go-to for replacement parts next go round.
