Verify VIN/engine and confirm the correct heat range and electrode design for your specific application before ordering.

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 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 (SIMR8A-9) 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).

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.

Legs curl up, panty liners don't stick, front and back are cut exactly the same.
I wear a pants size 8, and purchased an XL in these because I don't like tight underwear. They feel good, and fit well -- not baggy and not tight. However, the legs do curl up, which I might have expected if they were tight, but they're not. Panty liners stick at first, but not all day. And although there is printing on the inside back to provide a clue about what is supposed to be front vs back, there is no difference in the cut. The waist hits a bit lower in the back (on me) than in the front, which is not a deal killer, but, REALLY?? I'll keep these, but will keep looking for a better fit, and legs that don't curl up.
