Air Filters ( BMC / K&N / Stock / Green Dragon ) - which 1?
My BMC air filters are up for an replacement. What you think I should do?
(inputs on the actual HP gain with these air-filters are greatly appreciated)
Please vote and post inputs :-)
Jimmy- I, and many of the pros, do not want oil upstream of our MAF sensors. New OEM paper filters work fine and do not cost that much considering how infrequently they require changing.
Thank you so much for the input. I've had the BMC for the past 8 years without any problems. I even did a little write up on my site; which thanks to google had top its search results for "Ferrari + BMC + 360", here's the page : http://www.jimmy540i.com/bmc.htm
I just put my OEM air-filters back on and the car drives fine. Now when you mentioned "New" OEM paper filers, did you mean that Ferrari made an update or newer version of the OEM air-filters? My factory air-fliters were made in 2004.
I've searched on Ricambi and here's the result:
( Part #170689 AIR FILTER 360 - This item has been superseded to a new part: 190880 )
( Part #190880 - Air Filter - $38.97 each )
Here's the picture of the Air-Filter - Part #190880 on Ricambi's website:
Here's a picture of my OEM air filter which I took years ago (the one on the right):
Do you know if Part #170689 & 190880 are identical parts? How are they different from each other?
Also do you know for the fact that these oiled filters has any real HP increase via OEM? I searched and can't find any dyno / test results.
Jimmy- 190880 superceded 170689, so either would work if you found some NOS of the old part number. They are so cheap, though, hardly seems worth the effort.
I have not seen any comparison numbers I would trust.
Just took a couple of a short drives, strangely I missed the sound (or whatever that was) that BMC provides.
Upon my research, a few 360 owners had issues with the K&N (mostly CEL for being too oily), so I am prob gonna skip K&N though its 1/4 the price of BMC.
What is your input on this pic of the green dragon?
I know the Green Dragon Filter is technically the Green Filter @ Green Filter USA - Official Site
What do you think of this Green Filter vs. K&N vs OEM video?
Looking forward to your wisdom.
I have K&N on my TR for 10+ years, no problems.
Will stay with OEM on the 360.
I've done dyno testing on a couple cars like the 360 and a Benz CLK63 and compared stock filters, K&N Filters and the BMC Filter. There is NO performance gain. What I see is the oil film saturation on a MAF car and sometimes obnoxious intake noises due to improper sealing by the aftermarket filter gasket.
The only gain I ever witnessed was from the BMS foam filter, like used on PWC's and motorcycles. I saw a 1whp gain in that configuration. Unfortunately, none of these manufacturers make the foam filter in a drop in application for the cars.
I soak my K&N's in very hot soapy water overnight, then thoroughly rinse them and dry them in hot sunshine, gets rid of the oil issues, never any cel
Richard- The oil is what stops the dirt. Without the oil, all kinds of grit is getting past those filters, which are way more open than OEM.
I've talked to a couple different race engine builders. I won't run anything but a stock style paper filter on a street car. Especially if I want it to maintain leakdown and compression test numbers. Those foam style filters just keep out rocks and small birds. Too much dust get sucked in. On the race engines it doesn't matter because we rebuild them every year anyway. I crindged when I read that Richard washed the oil out of the KN and ran it dry. Certainly avoid any gravel driveways etc. Just no upside except they look cool. In some cases you actually loose HP with some of the so called performance filters. I've seen for myself where the large round filters that don't use a metal cover and allow air to come through the top as well as the sides cause a loss in HP. Causes some sort of turbulance issues with the air flow unless you go to the ones the sprint car guys use that are 6 inches tall.
The Swiss air is probably the best in the world and the roads are immaculately clean but your points are noted chaps
In that case you probably do not need an air filter.
well bro I went with this:
Jimmy- Kind of a waste of time to ask if you already had your mind made up.
