2004 Mazda RX8 BHR ignition upgrade, wires, spark plugs change out.
A quick video showing the RX8's tune-up and ignition upgrade to the BHR kit (which by the way is the best out there and highly recommended!). The trick to the trailing 1 (T1) coil nut is a stubby 10 mm and angling it, but make sure it grips good so you don't round it. A set a thru-ratchets work perfect for this job. Then after all is installed reverse the order to finish and enjoy the new performance and a job well done.
