k&n vs. MF
k&n vs. MF
I was reading the thread about the frankencar intake. I am planing on buyintg an intake, and I was wondering if anyone was having problems with the K&N filter on the frankencar intake. It was mention a few times in the other post but nothing that goes into detail of what really was happening. Could someone please explain to me what the problem is with the K&N filter.
Is the Monsterflow better or is it just personal preference?

There is no problem with the K&N out of the box. The problem is when people clean them and re-oil them. Too much oil causes build up in the MAF. Just follow instructions reoiling and you should be fine. This is my 1st K&N experience but from what I've heard others say, K&N has given them no problems whatsoever.
As the above member said, the problems w/ the K&N filters have been very few and the problem is not the design. One member said theirs came w/ too much oil(very rare but maybe true) Others don't seem to read the instructions that are very clearly written on the cleaning/re-oiling kit(s). It very clearly states NOT to overoil the filter.
What I would like to to know is what is the filtering efficency of the MS filter.

I'm not exactly sure about the whole thing but a Tactifying Agent, by definition and in laymans terms, is an agent that helps the substance in question to stick to the product it's applied on.
So based on that description, i guess it's a petroleum based agent the helps make the oil stick to the foam filter.
But don't take my word for it.

Could be. Oil sticks to paper & K&N just as well. You're right though, time will tell.

it's a NON petrolateum tactifying agent and that's why it wont' damage MAF's. it's a substance similiar to oil but it's not cus oil is petrolateum and this isn't.
hmm matt your gonna dyno with soundmike, that will save me the hassle, coudl you switch filters between cars too, so each car uses the different filters so we get a PERFECT idea of the diff. i don't see a big if any HP difference but it should be smoother.

My bad. Idea's mix-up in my mind every now and then. Thanks for the correction 
Steve, yep... hopefully next weekend. I'll do a baseline dyno (Bone-stock) then install the FI w/ MF. Run. FI w/ KN. Run. Matt will do the same. He's had his intake longer so chances are, given his ECU is already pre-adjusted, he might even give a better and more accurate result than i.
Hmm... come to think of it. Would be nice if someone from Houston can also lend us the Berk and Stillen intake. It'd be interesting to see the differences between all intakes.

The best way would be to bug MS for testing or find an online independant test. I found one for Accel(sp) foam oiled filters. Their site of course said their filtered great. They did compare them to I think K&N or cotton oiled and paper.
Generic K&N stuff that been around for years
http://www.racerpartswholesale.com/kn8.htm
Some Amsoil stuff
http://www.desertsundirectsales.com/k&nbitesthedust.htm
UNIfilter for motorcycles. Not scientific but interesting:
http://www.unifilter.com/performance-facts.htm
And I found it! Although not specificly dealing w/ oiled foam(gredy?) It's one of the more unbiased tests I've seen.

My comment regarding whether the foam used in the MF is better than the foam used in the HKS is never judge a book by it's cover. The only prima facia advantage MF has over HKS is that it uses a "petroleum tactifying agent" (aka "oil"?). This "agent" presumably assists in trapping particulate matter and provides a level of protection that the HKS filter does not. How effective it is at accomplishing that is anybody's guess.

I still would like to know.
According to the info at this site, which was done by a nonbiased magazine, the Apexi filter is the best for power and filtration. Also it doesn't use any oil so that you don't have to worry about oil contaminating the MAF.
Why isn't this filter being used with the Frankencar intake, instead of the foam type filter, which performed very poorly in the test.
Could somebody please clear this up for me?
Will the Apexi filter fit on the Frankencar kit?

For more info on A'PEXi air filters, check out:
http://www.apexi-usa.com/intake_powerintake.asp
It appears that A'PEXi makes a universal filter that fits an 80 mm opening. There's a problem, however. Even if the filter fits on a Maxima, the entire filter has to be replaced when it gets dirty. The cheapest price I've found so far for the universal filter is $65.00. Check out:
http://www.rollhard.com/apexintake.htm
I think I'll just stick with my trusty K&N for now. FWIW, I've never had a problem using a K&N filter.

.. For what it's worth , my local speed shop, I mean HUNDUH hang out , looked at me like I was from KRYPTON when I asked about MONSTERFLOW today... The kid behind the counter said : " The filter will cost you more than your intake " . I proceeded to tell him I drove a 2K2 Maxima.. he said.. : " Are those fast " .. at which point I walked out and went home, before I claimed the life of a future " Landscapers of America " memeber .....

I don't know if the HKS is oiled, but if it isn't than it can not be compared to the MF.

Unfortunately, the Amsoil filter was not tested by the same independent lab that tested the others. However, you can review Amsoil's own tests at the following web site:
