How long do OEM plug wires last?
I'm at 54,000 km (not miles) and I am changing out my spark plugs shortly. Any need to replace the OEM wires?
I am quite sure the engine bay does not get too hot considering my climate.

I would say your probably alright. Five years is when most change them out. It's only about fifty dollars. Hope you are getting NGK plugs.

the OEM wires are trash. I used a multimeter and measured mine at 2,7oo ohms of resistance (5 years old). The spec from mazda is 1,000-4,000 ohms. My new ones from BHR are 40-60 ohms...
