High flow air filter - BMC or K&N?
Hi Guys, do have the experience for changing the BMC of K&N air filter that get more quicker or just sound a bit better? Or suggest to change the entire air intake, APE?

I have the BMC intake filter for replacing the original one. I don't really notice the difference. I still haven't hit 2000km so still driving with caution. Hopefully when I go above 4-5 thousand revs there will be a difference noticeable.

A filter itself won't do anything. What's been referenced above is a cold air intake, and whether or not they have an effect is up for debate. When used in conjunction with a tune that accounts for the increased airflow and adjusts the fuel map accordingly, you can see performance gains - especially when coupled with a performance exhaust that helps move the increased volume of air away from the engine.
Be very skeptical about any claims of performance gains without a tune, however, much less with a simple air filter. |

I don't think its an issue for the majority of us. Ive been consistently using BMC or K&N filters on all my cars for years and never had any issue with them. But I don't live in a very dusty area... All tests from all manufacturers of these kind of filters show how well or bad they clean air from particles, which is something we simply don't know in paper filters. And it seems they do well... Of course you need to keep them clean, but I prefer to clean them every 10K kms, rather on having a paper filter for 30/60K kms as the car manufacturers say. The way I see it is they will not get visible benefits, but they are not doing anything wrong to your car, and no need to tune it, so if there is any benefit, even I don't notice, then I am fine. Same approach with oils...We all get crazy with getting the BEST oil, better than OEM...and we don't really know if there is a benefit there.

- For the high perf filters, what i can't understand is how more air you get in without getting more dust( silice dust is like diamond dust ) i guess the new generation oil we are using are doing the job to cover what dust is doing inside the engines !!! |

Do you know what is the filter properties of the OEM filter??...I don't I know at least what a BMC filter. And I can clean it as many times I want...

Only gain is increase in sound which is directly proportional to butt dyno performance improvements and a decrease in back pain related to a slimmer wallet If you search hard enough you may find Jim's original article which was very detailed but I would still take it with a grain of salt b/c he used it to justify the foam filter, which BTW still uses oil. Also notice the date we have beating this topic to death for a long, long, time... http://www.club3g.com/forum/3g-eclip...ly-better.html Last edited by omasou; 09-29-2016 at 11:58 AM.. |

Id like to have some clear facts on what a paper filter really "filter", and what a K&N or BMC kind of filters...we know they filter. Maybe I am missing something, and there is some real measures out there on what each kind of filters really perform. How also do you explain that some brands already have a BMC filter (f.e.) as OEM part?? Don't you think if they would offer less filtering (meaning I guess they would allow bad particles to get into the chambers...)...they would not be supplied as an OEM part??

The post above talks about some of this and remember race team need sponsors. The also take apart their engines and magnaflux them after each race, well at least PTG did or said they did. See if you can find Jim's original post about filters. BTW JC is a good guy and in no way am I trying to disparage him. Last edited by omasou; 09-29-2016 at 12:16 PM.. |

Again...K&N or BMC (or similar) report how they filter. tests they do...and how they do. You can believe it or not. I have never seen any official statement of any paper OEM filter making clear their properties, or restuls in ISO tests. Why then do I need to believe an PEM paper filter is better or more protective?? Yo don't know... In any case none of my cars ever had an issue or had to clean the MAF sensors, after hundreds of thousands of kms...and Ive been on these kind of high flow oiled filters for many years. They work for me, in the area I live.

OK...I leave this hear my friend. Maybe you don't need as well a "better" oil, a "better" braking lines, or pads, or fluids...as its all marketing and we are all stupid... Maybe its all marketing behind an M2...and it is only one more marketing story than a real thing...

BMC is top quality way better than K&N
AFE Pro Dry is also a good option.
