Air filters-OEM or aftermarket (not performance)
Discussion
Decided to have a tinker with 'er indoor's 'new' (S/H) Focus and start getting my fingers dirty again. While only having limited mechanical knowledge, I can do the basics.
As the S/H is a bit patchy, I'm changing all the filters. Being the weekend and Ford is shut, I went into the ubiquitous Halfords and was surprised at the £20 cost. (Last time I bought an air filter it was 4 shillings and sixpence. ) Looked on e-bay and there is a 'Coopers' Air Filter for her model for a tenner. No idea how much a Ford one costs, but are all non-performance air filters the same? I usually go with 'you get what you pay for', but can't see they can differ that much.

Coopers is a reputable brand and AFAIK are an 'OEM' (original equipment manufacturer). This means that they produce parts for vehicle manufacturers which are then rebranded as the vehicle maker's own (every car maker outsources the majority of their cars' parts).
I don't know if Coopers make filters for Fords though, but I doubt you will go very wrong buying from reputable makers like them or Mann/UFI etc.

Depending on how long you intend keeping the car,why not drop in a KandN. once in you can basically forget about it and if you keep the car for longer than say 5 services it will have basically more than paid for itself compared to 4/5 filter changes. It don`t really add more performance and might actually slightly improve ecomomy.
Cheers for the replies.
I've just looked at the old one and it's pretty clean so I don't think it's been in there too long. It's not my car so I'm not forking out for a K+N
I'm also going to do the pollen filter. After searching for it, I find it involves removing the fuse box first. You've got to love car manufacturers.

I always seem to buy Hengst airfilters for the BMWs. I believe they are OEM.
Not keen on the whole K&N filter thing tbh. Seen a couple of tests where they've demonstrated worse filtration than the regular paper item.
I've always understood that K&N filters need regular cleaning and re-oiling to maintain optimum efficiency.Not keen on the whole K&N filter thing tbh. Seen a couple of tests where they've demonstrated worse filtration than the regular paper item.
I would think that over the lifetime of a paper filter that's replaced at the proper intervals, the paper filter still wins.
