Comment: The dealership wanted to charge me $50 per spark plug (and I needed 4 of them). I was able to buy these here on Amazon at $17 each. Same exact spark plug, same part number for $68 versus the dealership's $200+ price. When I asked the dealership to match the price they told me that their 'cost' was $30 and didn't know how I was able to purchase the plugs so cheap. Great find!

Summary: Best plug for 13B-MSP/Renesis engine 2007-11-07
Comment: Stock Trailing Plug for Mazda RX-8 Rotary Engine ONLY.
If you want to try them on say, 13B-REW, you better make sure you know what you're doing.
Make sure you Rev your engine every week or so, or else the plugs might foul quickly.
Change them out no later than 25K miles. Dont believe me? You can try to go longer and see.
Oh by the way, this is probably the BEST plug for Renesis/13B-MSP engine. Unless you're going FI, nothing works better than this plug for this engine.
