Anyone have a thought on this ?? I am currently running the RB ones, The Mazda Shop i take my car to said that when he uses NGK, he has no problems, but with other companys they break faster. What do u guys think !!

 

Spark plug wires are spark plug wires. Any brand is good. You'll not see any power increase, but a good quality set will last for quite a while. My originals lasted 14 years and are still good. I replaced them with Megacore when engine installed.

 

the ngk wires are the "stock" replacement for the rex. i think the originals are ngk...

 

www.summitracing.com sell OEM NGK wires for $23 with free shipping last time I checked. I dont think they have them listed on the website so you have to call them and ask.
