I've just realised how over looked the Spark Plugs in my work vehicle have been!
I think they have been in their for 100,000k's
I just looked up the NGK website, good for 20,000 to 40,000km apparently opps
Funny how i've been fussy over Oils and Filters, yet completely forgotten about something so obvious!
Last time i did them, i changed the Plugs and Leads.
Van drove so well, less throttle percentage needed
Now its sometimes slightly harder to start and fuel economy has been getting worse and worse
I guess this could be plugs beyond their working life?
Any suggestions of better plugs? Iridium or Standard?
Engine is just a basic Toyota 2RZ-E
NGK Spark Plug - BPR5EY is meant to be the plug for the vehicle
