View Full Version : INTAKE info on proteges
October 14th, 2002, 05:50 AM
Since i give a crap about you protege guys i just wanted to let you know from my experience what you guys need to learn:
For those with RACTIVE intakes, i suggest you change the filter because those RACTIVE filters are a piece of crap.. THey do not filter very well in comparison to the more expensive intakes... And you are basicallyasking for trouble in teh long run by running those CHEAP @ss filters...
Next, for those running K&N and other oil based air filters, i suggest you becareful because you may ruin your Mass Air Flow sensors which will not be covered on your warranty as ar esult of aftermarket intakes..
THe problem is over oiling (EVEN if you just bougth the filter).. this oil can damage the very very sensitive filament in the MASS AIR FLOW SENSOR, as it coats this filament over time while you draw air..
I would suggest using a higher end filter like the APEXi filter which is a dry element filter..
As far as i am concenered, those foam filter have been known to degrade (such as the HKS shroom style or the MONSTER FLOWS0... What ends up happening over the long run is that the foam element can break up over time and get sucked into your engine..
ANy how i hope that information helps people..

Any suggestions on good quality 'drop in filters' (Brand names would help). For people who do not have modified intake systems?

I would use OEM because i dont think its worth your while to use a K&N panel filter... It truelly doesnt make a huge difference unless you are willing to remove the resonator assembly bbefore the actual air box (also know as the poor mans cold air intake)>.
The biggest reason that you can gain performance on an intake is that eh factory air piping and resonators create large restrictions in the effort to reduce sound.
However most intakes have an offsetting drawback because now you have exposed the open air intake to hotter temperatures and everybody knows (I HOPE) that hotter intake temperatures results in loss of performance...

Thanks for the advice. Will stick with OEM filters!

no problems dude, thats what i was running for the longest time, between an intake and stock..
my maxima still runs a stock intake!1!!!LOL..
I just could not justify using RACTIVE crap on my maxima, so i am saving up..

Is there anyway to know if a K&N filter is over oiled or not?
October 14th, 2002, 01:56 PM
Everyone is speaking a bit of truth here so I'll jump in. Ed is right with regards to the oiling issue and the MAFS. I've heard technicians talk about this.
And also with regards to the labrynth of arteries leading to the stock airbox that is restrictive too. That is why for $12.03 my patented GHETTO COLDRAM AIR working in conjunction with my drop in K&N filter is the most bang for your buck.
And Harold, before putting in my pre-old K&N I took a paper towel and just blot dabbed the excessive oils for my own piece of mind. http://msg.toprotege.com/iB_html/non-cgi/emoticons/blush.gif
Yet the microscopic oils may still do something though. That is why I'll just swap my OEM when I get my servicing done and play Shaolin Idiot to still get my warranty.

Thanks Michael..i will probably do that when i put in my intake...
Check the chinese food post....=)

so then what about Injen CAI? anyone hear about the effects of that on a pro?
October 14th, 2002, 07:56 PM
Also,... any thoughts on the AEM CAI or the AEM short ram?

Most likely most of these filters are actually oil treated filters hence their reusablilty..
Unfortunately many of them require reoiling after cleaning but i mean spending 100dollars after 40,000kms is really amounts to nothing each timei to replace a dry element filter such as APEXi...
Some brand new K&N filters may also have problems of being over oiled.. The oil does nothing to the engine except the sensitive sensro wire.. I had to replace my old protege MAF after 40,000kms luckily under warranty..
I mean it might be rarer in protege, but we nissan guys have had many MAF failures as a result, and it is a very expensive part to buy..
INJEN, AEM might be using K&N brand as most... Its all really depends on how many MAF failuers have been encountered in teh thrid gen and 2nd gen proteges..
HONDAS all have no problems because they have no air metering systems like a hot wire mass air flow.. This is because they use a speed density system which refers to mapping fuel air curves based on different conditions..
Thats why a fuel pressure regulator helps them out so much in terms of performance because their stock ECU doesn't really compensate for the increase airflow in the intakes as much as a MAF based car would because proteges do compensate for increased air flow..

Hey MiniRX7 do you know if you can clean your MAS element? I just swaped my stock intake back in for the winter and I noticed that mine looked kind of fuzzy. My intake setup came apart at one joint and I ran unfiltered air for a while. http://msg.toprotege.com/iB_html/non-cgi/emoticons/sad.gif

Umm.. that is a very touch question, so much as finger oil will totally damage the MAF..
I would consult a mechanic familiar withthis.. If not, maybe some dust air cans (like spray can that shoots air) can clean it wihtout damage..
However if the MAF is functioning fine i would probably say leave it for now... You might be causing yourself more trouble screwing with it..

Check out my thread regarding the recall for the 1.6L engine under 'Under The Hood'.
October 14th, 2002, 09:04 PM
Whoa.. read your other thread, how in the world did you drive 3 years without noticing..
A busted up MAF renders the car close to undrivable....
Thats strange.. when mine was going, it was so bad, i couldnt rev..

I got the Mazdaspeed filter from the Sport-20 touring kit, ordered through Mazda Motorsports. It ended up being more expensive than a K&N but I figure it's safer because there's no oil and it's sort of a factory part (and marketing bs says it's 20% better flow than the stock paper one). It's a triple-stage foam filter that can be cleaned and re-used.
Just listing another option for those of you wanting a drop-in upgrade.
October 15th, 2002, 10:04 AM
Ugh....you had to post this information a week after I bought my K&N drop in filter! Damn...oh well, rowen how much was the mazdaspeed filter?

Mike_Moss messed up his Airflow sensor, and he has some serious problems at high rpm. Ed, this is a legitimate concern, about oily filters, ruining the MAFS, but does anyone actually know of someone who has had one ruined? how much was replacement?

I think it was close to $100 by the time it got here from California.
Although now the price on MazdaMotorsports is $80 USD..
All the instructions are in Japanese as well so I'm not sure how you're meant to clean it exactly :|

I'm sure we have more than enough translators here on the board. My translation of the ancient Shaolin Text is just only that. I don't know what I'm transcribing half the time. It bloody hieroglyphics!!! http://msg.toprotege.com/iB_html/non-cgi/emoticons/confused.gif
