          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).

            Comments about NGK Laser Iridium Spark Plug (RE9B-T):

            The product is great, NGK makes great plugs, and nothing can make a rotary run better than a new set of plugs. However the set of plugs I received from advance had to be exchanged in the store for a new set. In shipping they literally just took the 4 plugs and threw them into a small box, no padding. These are [$] plugs that cannot be gapped. One of the plugs didn't even have the cardboard protector around the electrode like the others did. So, as expected, all 4 plugs had different gaps, even between the 2 leading and the 2 trailing plugs. I exchanged them at the store, and the store members proceeded to give me the new pair (Made me happy) but then just placed the damaged goods back onto their supply shelf because they saw no visible damage to the products. Now whoever gets these plugs next are going to be out of luck when they go to install them. It could have all been prevented if they just shipped [$] spark plugs properly.

              They are a direct-fit replacement for factory plugs. Everyone with a rotary engine knows the best is from NGK. They are the same plugs Mazda puts in the rotary engine with different packaging and price too..They are way cheaper than getting them at the dealer.

                  I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not solve or be the problem.
