            Unless you are running an aftermarket turbo and need a colder plug, these are THE plug for the RX-8. Buy them now and be happy. My gas mileage is up 3 to 4 mpg after changing the plugs, wires, and coils (plugs were the major factor).

            Outstanding deal Advanced Auto Parts! I got good products, $30 off my order, 50 in store credit, the parts arrived on time, and free shipping. Nobody could top it. My car runs much better and I saved a nice amount of money in the process.

                  This is the exact same stock part. and Mazda selling them @ double the price. Advance Auto Parts always have some sort of discount which makes this an even better deal.

                      NGK plugs for rotary engines are expensive. At [$] each plug, they need to be replaced every 30- 37 thousand miles. They are good plugs though and NGK makes good stuff.
