replace them when they wear out. Yeah changing the wires after 10 years isnt a bad idea.

k, but how do i know if they need to be replaced? and are all the "high performace" ones worth it? like the RB kit or these ones with inline capacitors and stuff?

ULTRA wires are good. I dotn know much on the US companies.



As for the ones with WIRE grounding, i would stay clear, personally. Even though we sell them, i dont recommend them on rotaries..



If you get a miss-fire, change spark plug wires.



Spark plug wires on at least the FD seem to be changed less due to the GREAT placement of the wires. I would change them as the same as any other car, like you change your oil and your plugs.

yeah back when i got my car..... my wires were so bad that i could actually see sparks coming out of them.



anyways thanks to rx7trix.. the stock nkg platenum plugs are on the way, 9's all around

FikseRxSeven

which set of spark plugs tend to wear out faster? leading or trailing?

rfreeman27

they dont really wear out in that sense. They should be changed at the same time.

FikseRxSeven

nevermind..... i did a research and the leading fires twice per rotor face and trailing only once

yep that is why there is only one leading coil. waste spark design
