New classic owner - couple of questions

[Baskey]

Evening all

Last week I picked up my first subaru, an impreza wagon turbo - uk spec. It's a nice car with fairly low milage,completely standard, Fsh and being a 2001 model I'm guessing one of the last classic shape Imprezas ?

Im looking to do my 'getting to know my new car service' I do whenever I buy a new car but I have a few questions .....

I'm not sure what spark plugs to use, eurocarparts list loads, even different models from the same manufacturer what do you guys recommend for normal driving?

I presume decent quality 10/40 oil is the way to go? Although the oil was recently changed its very dark in colour, is this normal ?

Cheers guys, iv ordered the parts now and I will get them fitted on the weekend.

I havnt ordered the maf though but I think I probely will (mine looks origonal). I have two flat spots / slight misfires between 2-3k revs. If it's still there after I change the plugs I will change the maf. I presume I need to go for a decent make, it seems you can get them on eBay for as little as £20ish but I presume this is a false economy as decent makes are 4x as much ??

I will also get some pics up shortly, I'm just waiting for a wing mirror to turn up as the current one is smashed.
