Which HT leads - Disco 2 V8

Morning all, Im thinking of changint the plugs and leads on my discovery as i have a very slight missfire when warm, Its only slight and just initially if you rev it a little.

Anyway which plugs and which leads do you recommend and where from?? Paddocks?

I was also thinking of changing the maf sensor too as i thought this may also be a cause are there lots of different ones or just 1 type for the Disco 2 V8?


Thanks in advance, Steve
