Review on NGK (9369) High-Performance RC-TX15 Spark Plug Wire Set for Enhanced Engine Optimization. by Andrew Roberts

Great spark plug wire set for MR2 Turbo. Toyota factory spark plug wires are black NGK wires, blue wires are upgraded premium NGK spark plug wires. There is no benefit to using the more expensive aftermarket spark plug wires (which I've used before) as they don't produce more power and the spark plug wires don't last longer. I found a problem: the coil wire to the distributor didn't have the plastic clip that came with my previous NGK kit. Not really a problem as I just used one from my previous set on a new set of NGK Blue spark plug leads. Also, the brass spark plug wire clamp between the coil and distributor (at the end of the distributor cap) needs to be modified slightly to fit properly. I suspect this is because the 1993+ distributor cap is slightly different than the 1991-92 distributor cap.
