I contacted a few filter manufacturers and have settled on trying a BMC replacement filter. for a short period of time and thought i would let ppl know what it is like for a simple drop in filter
Why choose BMC?
I wouldn't touch K&N even though we sell them where I work, i donn't like the oil in the bags they are supplied with as it seems to be soaked in it, also when held up to the light the gapping holes in the filter media scare me. I could have gone for the VWRacing (ITG foam filter) but after speaking to ITG I wasn't confident the vague claim was worth buying one. (see response from ITG below).

In normal European road use, the filter will achieve an efficiency well in excess of 99% and remove a very high proportion of particles down to 3 microns and a good proportion below that. In very dusty conditions the efficiency may drop off a little, possibly to around 97%, with the particle size drifting up towards 5 microns.
Best regards,
JR make a very good cotton filter to 2 microns and 99% efficiency, and have had some good reviews but I settled on the BMC due to its use in road applications from the factory, they state (everything above 7 microns is filtered out ). Some OEM filters filter everything above 10 microns so its in the zone of acceptability for a try.
BMC are fitted to a lot of motorsport and with the changing engine rules in F1 these engines need to last many races, and many hours of inducting high volumes of air. I understand some forms of motorsport strip engines down quickly and appreciate the slightly false claims of "if it's good enough for motorsport its good enough for me". However 2 of my favourite road cars I believe also have them fitted as standard from the factory, and this is the main reason i settled with BMC. In my eyes If Porsche and BMW think its usable and meets standards of filtration in a moderate climate I am happy. Obviously the VW Golf range needs to be suitable for every climate and condition, and so they fit a 1 type filter to cover all possibilities from the factory. Where as the CSL and RS4.0 are likely to be used in a moderate climate and perhaps the manufacturers chose BMC for this reason, OR perhaps they just liked the colour

Don't get me wrong I haven't fitted this to claim any performance improvement but thought I would share my thoughts. For a start there is ZERO oil anywhere in the bag, this filter is pre-oiled and made (according to the stamp) 28-04-2015. This straight away gives me some confidence of the level of care that goes into the product. no oil seeping out of the bag, unlike K&N which are always swimming in oil and sometimes remnants of leakage in the cardboard box. It's nice to see a production date so you know the filter hasn't sat around for 2 years. The filter is heavy, solid and the rubber moulding surround feels very robust, holding it up to the light shows a consistent weave structure. It fits the air box perfectly and without any need to force the filter into position. (my sound baffle is removed from under the filter inside the air box). If any one is interested in a replacement filter I hope this helps.
basic fitting instructions and stickers are supplied, where it states that it needs to be washed and re-oiled approx every 25,000km
