Vehicle Compatibility

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 (14,00) 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 (LKAR7B-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).

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.

Sturdy Oil Filter Wrench
Color: Silver
I bought this sturdier Oil Filter Wrench when I was having trouble removing the oil filter on my 2003 BMW 1150RT with a stamped steel oil filter wrench that I had previously used. It still slipped, but adding a strip of grit mesh between the filter and the filter wrench saved the day. I still like this cast aluminum filter wrench better than the stamped steel one.

Does not fit Chevy LS3. Too big.
Color: Silver
Does not fit 2014-17 Chevrolet SS (LS3 V8) genuine GM oil filter. It slips. It's supposed to measure 74 mm flute to flute, but actually measured 77 mm with calipers. This wrench looks like it was used and was re-packaged with office tape. I purchased correct size from dealer that fits perfectly.
