gdfmacfarlane 2 Posted March 20, 2014 Report Share Posted March 20, 2014 Just got a second hand BMC CDA system and want to give a good clean before I fit it. The BMC cleaning kit is around £20 compared to the K&N air filter service kit which is less than a tenner. Does anyone know of any reason why I shouldn't just use the K&N kit?

Lukey. 381 Posted March 20, 2014 Report Share Posted March 20, 2014 I've always use the k&n kit gdfmacfarlane 1 Link to post Share on other sites
VR6Pete 1,455 Posted March 20, 2014 Report Share Posted March 20, 2014 Never used a cleaning kit! Took mine apart, gave it a good tapping out warm soapy water and rinse, dry back on the car?Club Chairman gdfmacfarlane 1 Link to post Share on other sites
gdfmacfarlane 2 Posted March 20, 2014 Author Report Share Posted March 20, 2014 I thought about that this morning, just using some washing powder detergent and giving it a soak and a rinse through, but for the sake of a few quid I may as well get the proper detergent cleaner. The kit's have oil in them for re-oiling the filter after it's been cleaned too, I'm not 100% sure what the purpose of oiling them is, whether it helps catch dirt or helps the air flow, I don't know but I'll give it a go anyway. Think I'll give the K&N kit a shot! Link to post Share on other sites
khare 12 Posted March 20, 2014 Report Share Posted March 20, 2014 Is the bmc a dry or a wet filter? If it's a dry filter all you need is soapy warm water and let it dry. If it's a wet filter then you need the appropriate cleaning kit, which will require a re-oiling once the filter is dry. The wet filters harm the maf. Link to post Share on other sites

Its a BMC CDA, not sure about the internal filter, I figured they were all the same and just needed cleaning and re-oiling. Link to post Share on other sites
VR6Pete 1,455 Posted March 20, 2014 Report Share Posted March 20, 2014 I thought it was a dry kit as the last 2 I've had have been bone dry from new ? Link to post Share on other sites
Marneus 78 Posted March 20, 2014 Report Share Posted March 20, 2014 Don't oil it! When I had my 1st VR6 I took it to a "reputable" VW specialist. They oiled my induction kit which in turn wrecked the MAF, VR6 MAFs don't like the oil. Link to post Share on other sites

Thinking about it mine was also dry, although I didn't check. Just wash with warm soapy water and let it dry naturally, don't get a hair dryer on it. As I said, oil will kill all MAF sensors.

Lukey. 381 Posted March 20, 2014 Report Share Posted March 20, 2014 Are you drenching the bloody things? You're only supposed to show it the oil, then the SUPER FINE COAT of oil absorbs dust and aids in the filtration process Link to post Share on other sites

gdfmacfarlane 2 Posted March 21, 2014 Author Report Share Posted March 21, 2014 I have heard of MAF sensors being affected afterwards but as Lukey said I think that's from over-oiling. I also saw somewhere that people "pre-suck" (technical term) them with a vacuum! VR6Pete 1 Link to post Share on other sites
