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 Mercedes-Benz?
This part (PLKR7B-8E) 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.

Very easy to use
Size: 12 Pairs / 24 pcs
I have an Onkyo audio/video receiver along with an Emotiva amplifier. Both have speaker "post" terminals which will accept banana plugs, OR I can connect the speaker wires by unscrewing the posts, poke the speaker wires into the terminals and then tighten the posts. The problem with poking the wires into the terminals and tightening the posts vs using banana plugs is that there is a risk of the wires touching the metal on the back of the chassis or touching other speaker wires, causing a short if one is not careful. With banana plugs, they simply plug into the back/top of the posts, eliminating the rsick of a short circuit. They can also be unplugged very easily if needed. Banana plugs are DEFINITELY the preferred way to connect speakers to an receiver or amplifier if they have post-style terminals. These particular banana plugs came in a package of 12 I believe. They were very reasonably priced, and simple to connect to the end of the speaker wires. Simply unscrew the banana plugs, use a small, standard jewelry screwdriver and loosen both of the set screws, insert the speaker wire, then tighten the set screws, and then screw the banana plug back together. The plugs have either a red band which would typically be used for your "Right" speakers, or a black band which would typically be used for the "left" speakers. The banana plugs insert into the top or front of the speaker terminal posts on the amp and receiver. They fit VERY snug, and so I did have to apply just a little bit of pressure in order to insert them into the posts, but once plugged in, rest assured they're not going anywhere. They are snug. I highly recommend these.

Quality & Durability
Size: 2 Gauge Cable, Color: 20 ft Black + 20 ft Red
If you need cable for your power supply and ground. Look no further. This is quality from the copper to the insulation. I wasn't sure about buying wires off amazon but this is my new favorite. Done several trucks and they are holding up just fine.

EXCELLENT FLEXIBLE BATTERY CABLE
Size: 2 Gauge Cable, Color: 10 ft Red
This 2awg gauge cable works perfect, nothing more nothing less. The rubber coating on the wire is made with some kind of clothlike material, will work great to resist engine heat with it's thickness. It's real OFC flexible cable very durable and worth the price!!
