Ok right now on my 90 n/a i have a set of original ngk plug wires, i have a set of Racing Beat plug wires that the guy i bought the car from gave me there the 8mm, high performance ones, and he said something about them or something i dont know, my question is how can u test wires to see if they are good, they are the ones that have the liftetime warrenty, so there supposed to be good, i would like to put these on my car, how can i test to see if there withen specs and are still good, they look brand new,

 

anyway to do this

 

Visual examination for cracks, burn marks, etc on the wiring insulation & boots, and a resistance reading on the order of kilo-ohms to verify serviceability...

 

like already said check visually and take a resistance reading(ohms), thats really all u can do. leading wires on an fc are gonna have more resistance cuase of the longer length \

 

check the resistance of the wires.

 

Alright thanx, and what do these bigger high performance wires do for you in performance, i have 7mm ngk wires, and these are 8mm Racing Beat wires??

 

Supposedly give you a better spark, via better construction, and less internal resistance maybe...

 

ahhhh ok thanx

 

Keyword maybe. Anyone have dyno proof of going from 7mm to 8 or 8.5mm. I'd be interested.

 

yeah me too
