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 your vehicle?
This part (CPR8EA-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).

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.

Beautiful and works great.
Color: Navy, Size: 10 Foot, Color: Navy, Size: 10 Foot
I decided to try this because my old umbrella had seen better days and it was time to replace it. I am very pleased with the quality and the ease of assembly with this umbrella. It’s very sturdy and I like the quality of the fabric and the metal. It’s very easy to open and close and it makes my patio look great. It gives me the perfect amount of shade and the fabric thickness is perfect at keeping the harsh sunbeams from getting through. I also think the price is great for what you get. I would definitely recommend this umbrella because it’s made well and works well. It’s also very easy to clean. I just use my garden hose and spray it down and let it air dry. It also fit perfectly in the stand I already had and it works great. I am very happy I got to try this out.

Great replacement patio table umbrella.
Color: Tan, Size: 10 Foot
After a windstorm destroyed my old umbrella on our patio set, I was looking for a new one that wouldn't break the bank but also held up to the direct sun of the summer months. This umbrella did not disappoint! The material part of the umbrella top seems like it is nice and thick and the stitching is overlapped in the corners which should provide a lot of strength for the windy days. I really like the neutral colors of the fabric, as that will go well with the rest of my outdoor furniture. The medal pole portion is perfectly straight and the pivot point connection seems nice and tight. I would think that this umbrella will stand the test of time. No assembly needed, just pull it out of the box and extend the fabric.

Incorrect height shown in listing image.
Color: Tan, Size: 9 Foot
I purchased these for their tall height to go in the ground, but they are too short and I hit my head on them. The height shown in Amazon's pictures does not match the actual height for the 9- and 10-foot umbrella. The heights are something more like 90-95 inches rather than the 108 and 120 inches indicated. The 9- and 10-foot umbrella description seems to refer to the diameter of the umbrella instead. I have returned them, but Amazon has not yet corrected the listing.

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty. The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home. Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down. They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price. If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.

Reliable, Comfortable Dumbbells I Actually Use Every Day
Style: 12 Pound, Pair, Style: 12 Pound, Pair
I’ve been using the Amazon Basics Neoprene Dumbbell Hand Weights daily, and they’ve honestly been perfect for my routine. Whether I’m doing a quick morning workout or adding resistance to a longer session, these have held up really well. The neoprene coating makes a big difference—it provides a comfortable, non-slip grip, even during longer workouts or when my hands get a little sweaty. They’re also easy to clean and don’t have that strong rubber smell some weights can have. I really appreciate the hex shape too. They stay put when I set them down (no rolling across the floor), which makes switching between exercises quick and frustration-free. The weight feels evenly distributed and well-balanced, so movements feel controlled and smooth. Overall, these are simple, no-frills dumbbells that just work. If you’re looking for reliable hand weights for everyday use—whether you’re a beginner or just need something dependable for home workouts—these are a great choice.
