Spark Plugs

[Redline]

It’s the net present value too as well as paying for something that you might not get the value of.

If you spend an additional £50 now for something that you might not use that spend for another ten years, that £50 is worth more to spend on something else now than tying it up and not using it. Also it’s quite likely that those plugs will also be half the price in ten years time.
So, on that basis there is absolutely no point spend more than you need to.
Only worth it if you get an immediate performance or efficiency saving - which you won’t.
Spend less on good quality we’ll manufactured plugs.

Ah. Good point, well made.

But, to counter that, we don’t have to spend lots of time and money on replacing rusty bits and perished rubber
It’s well worth it feeding those horses

Not forgetting head gaskets and the thrill that a six pot gives.
