Verified Customer Reviews for NGK Standard Spark Plug
KTM RC 390
20 Jan 2026 by Anonymous
No hassle at all, great quality spark plug.
The reason I buy from the sports bike shop is because they’re knowledgeable about what they sell. After confusion from other places as to which spark plug to buy, I asked which spark plug would fit my bike and they recommended this one. It was installed and it worked perfectly on a Ktm RC390. I buy quite a few parts from here as the price is always competitive and even if they don’t have it in stock it will be there the next day in most cases, with no commitment to buy. Fantastic place.

NGK Standard Spark Plug - LKAR8A-9
NOTE PRICE PER PLUG
| Triple-Gasket Sealing Process Virtually eliminates the possibility of combustion gas leakage through the shell. Most other manufacturers only use two seals. Solid-Copper Core Produces a more powerful spark with less firing voltage. Other manufacturers use a "copper coated" center core. Corrosion Resistant Zinc Chromate Coating double dipped for maximum protection. An NGK exclusive. Alumina Silicate Insulator Virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance. Corrugated Ribs Eliminate "flashover", which can cause misfiring and engine damage, especially in damp environments. |  |
