K and n cone filter upgrade#
The improvement will be from the new melt blown polypropylene cotton filter layer which will upgrade the breathability factor (respiratory resistance) of the mask.

The Powecom KN95, made to the new standard, will be the same size, shape and use the same production process. The Powecom ® KN95 is manufactured by Guangzhou Powecom Labor Insurance Supplies Co., LTD., which has designated Bona Fide Masks™ as the premier face mask distributor in the United States. The Powecom ® KN95 personal respirator, Made to the NEW GB2626-2019 Standard with Better Breathability, ships from stock directly from our Mount Vernon, NY warehouse, is a respirator face mask made of a multi-layer filtration system of non-woven breathable fibers and is utilized globally. my engines been running smooth no problems for that long so is it really a huge effect if dirt passes through into the engine? i also seafoam the a4 every year or so.Bona Fide Masks™ is the EXCLUSIVE DISTRIBUTOR for Powecom® in the United States & Canada! I use k&n drop in filters for most of my cars some have been running for about 10 years now i have an audi a4 2003 k&n filter for that as well and i have been taking care of it, doing regular maintenance and stuff. I love my bmw too much to damage it and i know how much it can run me for repairs so any insight would be helpful. To anyone who knows anything about motors and intakes, does having a less restrictive filter do anything for naturally aspirated engines? i know less restrictive = more dust/dirt entering the system but can it be justified for something like throttle response or any other upsides? Wow.after reading that im having some serious concerns for my k&n. Here is an indpendent test conducted on varous drop-in filters. Most if not all let more dirt into your engine even if properly maintained. Stick with the OEM filter since you get NO benefit by using a K&N or any other aftermarket filter. once again didn't find any comparisons between a MAHLE and K&N. I couldn't really find any comparison specs as in the density of microns.

With a K&N Air Filter, there is no sacrifice. In contrast, most other media can not maintain the same balance of airflow and filtration throughout the filter's life without sacrificing one or the other. The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection. The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton’s microscopic strands. you should be fine.Īppears to be similar material to the K&NĪ K&N Air Filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. I would say keep it clean with oil as per the manufacture recommendations. so not really sure if K&N is Bad, but all performance filters are similar. and then tried MAHLE one of the OEM Manufactures. for easy, i just looked up K&N website to see what the micron rating was. Anybody else make the switch? Is it advised? Should I switch back? Any advice from the forum would be appreciated.įor shits and giggles i tried to look into this. After the fact, a local BMW garage owner said I should immediately switch back to a normal filter because the K&N would let too many contaminants through and it would destroy the charcoal filter which can't ever be replaced. I recently replaced my engine air filter with a K&N air filter.
