Does my cap distributor on my xterra 2000 need to be changed at 100 000 km? Its not cracked. Do bosch plugs do the trickor should i use ngk plugs. Thanks:popcorn:

Yeah, cap and rotor should be replaced by now, plug wires too.
Plugs, yes, NGK only, the Nissan engines like them best.

I Put On Some Bosch(at 98 000 Km And I Haven T Had Any Problems. It Runs Smoothly , But I Will Try To Change Them .i Find The 6th Plug Is Horrible To Change. Got Some Tips On That Last Plug? Thanks
