When I was searching for the right spark plug for my vehicle, I came across two popular NGK models: the NGK BU8H and the NGK BUHW-2. Both have their strengths, and I want to share my experience and insights to help you choose the best one for your needs.
Understanding the Basics: What Are NGK BU8H and NGK BUHW-2?
First off, both the BU8H and BUHW-2 are spark plugs made by NGK, a well-known and trusted brand in automotive parts. These spark plugs are designed to fit specific engine types, and their differences can affect performance, fuel efficiency, and engine longevity.
Key Differences I Noticed Between NGK BU8H and NGK BUHW-2
- Heat Range: The NGK BU8H has a different heat range compared to the BUHW-2. This means the BU8H can handle slightly higher temperatures, which is useful if your engine runs hot or if you push it harder.
- Design and Construction: The BUHW-2 is designed with a washer seal, which helps in better sealing and preventing compression leaks. On the other hand, the BU8H uses a different sealing method. I found that the washer seal on the BUHW-2 gave me a bit more confidence in a tight fit.
- Application and Compatibility: I checked my vehicle’s manual and cross-referenced the part numbers. The BU8H is often recommended for certain motorcycle models and small engines, whereas the BUHW-2 is frequently used in other specific models. Always verify compatibility before purchasing.
- Performance: In my experience, both plugs performed reliably, but the BUHW-2 felt slightly smoother during cold starts, likely due to its design.
Why I Chose One Over the Other
For my motorcycle, I originally used the NGK BU8H and was happy with its performance. However, when I upgraded parts and wanted a better seal to prevent any compression loss, I switched to the BUHW-2. The transition was seamless, and I noticed a small improvement in engine responsiveness.
Price and Availability
Both spark plugs are reasonably priced, but availability can vary based on your location and supplier. I found the BU8H slightly easier to find locally, while the BUHW-2 sometimes required ordering online.
Final Tips from My Experience
- Always check your vehicle’s manual or consult a professional before switching spark plugs.
- Consider the heat range your engine requires; using the wrong heat range can cause poor performance or damage.
- Look for genuine NGK parts to avoid counterfeit products.
