splutter, cough, spit, splutter... that's it, car has to go

Response from K&N below.....

"Hello

Thank you for your enquiry. 33-2001 cross refers to your OEM part number. 33-2029 and 33-2768 are different sizes to 33-2001 and have different OEM part numbers.

Regards
Don Marshall"

The OEM Part No I gave then is what a 'certain parts CD' shows for S2, RS2 and S4. The plot thickens.

Ah, the old 191 129 620 as fitted to all the above plus just about every injected car built by VAG in the late eighties to early nineties.

I wonder if K & N are trying to pull a fast one on the RS2 and S4 owners? Are they more expensive than the S2 version? Clearly, because they are faster or bigger then they must use a better filter

I'm considering an ITG, although they are oiled they claim you never have to oil them again - about £30-35 if I remember.

Also green filters are supposed to be good? http://www.needforspeed.co.uk/green/index.htm

I just got one of their foam cone/cylindrical filters - the really big beasty - 200mm x 180mm diameter (ish) and the instructions I have tell you to wash it and re-oil it regularly - If the filter is oiled - it is so it catches small particles - you'll want to eventually wash these out and re-oil.

And if you order an ITG filter, order the oil as well - as it doesn't come with the filter.

I'll be running with screens on the MAF to see if any oil is coming through - an then take them off again when I'm happy it isn't sucking the oil off the filter.

I really must start thinking before I post stuff I was convinced I had read smoething about not needing to oil them - d'oh!

The foam principle looks like a good one. If you look at the later Dyson vacuums they have a lifetime foam filter that just needs washing with water every 6 months or so. The filtration is bloody amazing - either that or I have particularly dirty carpets

I noticed that Green filters come pre-oiled but it says nothing about re-oiling

I'm sure I read that somewhere too - and was a bit annoyed that it had to be oiled when I got it in my hands - I'll see how it goes.

I had an ITG MegaFlow bolt on filter fitted to the weber carb on my '86 passat estate and that wasn't oiled. Nor did it mention anywhere that oiling was required.

ITG list the VAG equivalent as WB-481. They mention dust retention fluid on their website but also say that the Pro Filters never need cleaning. They don't list the filter as being the same as the RS Turbo though.

I would be wary of K & N's application guides as I once bought one for an '86 1.0 polo (I was young - you have to start somewhere and when I was finished she'd show a nova sr a clean pair of heels:nana: - four days she lived with her new 15"!!! alloys - but I digress) and the box had it as being the same as a 1.3 vauxhall astra. They look the same but it never quite fit the airbox. I wouldn't be surprised if they try to amalgamate similar filters into one.

I'm on holiday for a week, but when I get back I can give them a ring and ask them. They're based in coventry about 13 miles from where I live.

Come to think of it, Jason, my mechanic has just bought a K & N for his A100 S4. I'll see if he has the part number for it.

I knew I'd read something about not needing to oil them! Maybe it's only the direct replacement panel filters that you don't touch?

When I talked to ITG they said the ABY S2 filter was the same size as lots of other VAG cars. I'm sure it is the same as a Passat and also the 2.8 V6 Audi 80?

Are the ABY and 3B the same?

[s2avant]

It's the same as most other Audi 80's/100's/Cabrios/Coupes of the same vintage, a couple of older Passats and MKII Golf GTi's.

As far as I remember the 3B filter is the same as well.

I suppose it's possible that the open filters (i.e cones etc) need to be cleaned as they are exposed to more pollution under the bonnet than direct replacement filters.
