aftermarket intakes arent good for your engine?

my mechanic told me that the air filters for the aftermarket intakes are bad for your engine cause they dont filter out as much stuff, because it needs more air flow for power.
does it really mess up your engine and stuff?

No!
I've been running one for the last 284,000 miles and have not ever had a days problem with my motor taking a breath

Some mechanics talk thru their (donkey's behind's).....

what kind of intake and air filter do you use?

As long as the wet oil type filters have oil on them, they filter out fine. Stick with a brand name though, like K&N.

**I just happen'd to use an OBX Cold Air Induction Intake System part #127-1601-1
Air Filter is by them also and is made for wet weather also, i think my gain is around 7 to 13 H.P. with their unit..**

Hey guys, sry to kinda jack the thread but I was wondering where I can buy the filter cleaning kit for an AEM Dryflow filter? Thanks:)

i dont think it has a cleaning kit but i dont have quicktime installed to watch the video ^_-

There is a specific cleaning formula from AEM for this filter.......I have one too. They warn against using anything else but that may be crappola, I didn't want to chance it myself. It's shown on the video link above that marbro provided. I got mine from Sam@missionspeed.

That guy's mechanic is right about aftermarket air filters.

take a look at all of those charts particularly the ones that how much dirt was allowed to pass through the filter...

Some indeed do allow more dirt to enter but the REAL test is having your oil analyzed. High silicon levels are a sure sign of too much dirt passing through although other things could also cause it. I have seen oil analysis' with K&N cone filters that had LOWER silicon levels than with the OEM paper ones. There are too many variables for a blanket statement that "all aftermarket filters let more dirt through". That just isn't so.

The reason I posted that test was it was controlled so that other factors such as vaccum leaks, etc are not taken into consideration. Some people live in areas where there is a lot more dirt than others, etc too many variables.. if an OEM filter is not properly installed, it is quite possible for the oil to be dirty...

And if any filter isnt properly installed it becomes the same situation. Non oiled cone filters that are generic brand i can definetly believe let in more dirt and etc then stock filters. But you have to look at the fact that you have most stock intakes that let in 1/4th the air as well

the thing that I actually liked about this test (even though I have a REALLY hard time agreeing with it) is that they use a constant amount of airflow and it's not based on intake. The issue I have is that if a stock airfilter catches more dirt then how is it possible that it maintains a higher airflow rating? if it's got more crap plugging it up because it's catching more crap then how is it possible for a K&N that has less crap built up on it to pass through less air than a stock one when they've both been subjected to the same amount of dirt?

Actually the K&N has a higher flow rate until it starts getting restricted then it just start restricting at a very exponential rate type of curve...where as the stock filter is very linear in its ability.

Go down to where it shows inital restriction and you will see that the K&N is the least restrictive side of the chart and the a/c delco is on the other side (most restricive)

are you guys talking about cold air or short ram intakes?

It doesnt matter, controlled situations do not equate to a standard for every car in every city. Not that i wouldnt mind having an industrial high flow fan constantly blowing into my intake.

Very good point and the test does appear to be done well, I had seen it before. What it really boils down to, in a way, is So What? Not knocking you or their findings, please don't misunderstand. My point is this: Ever heard of a daily driver having it's engine destroyed from a less restrictive air filter? Like Wheelbroker, I have run several cars well over 150K all had a K&N. All were in pristine running condition when I sold them and I always got top dollar. X passes more dirt than Y........... It just might be much ado about nothing.

I use the AEM drystack(?) now but that's because it just happened to come with the short ram that's now on the car. Cleaning it is a two edged sword; you don't have to deal with the messy cleaner and re-oiling but you do need to use AEM cleaner (so they say). I haven't cleaned mine yet but I am curious how long it will take the dry since the material is more dense than the cotton gauze. As far as the unknown amount of dirt that may or may not enter the engine over the next ten years......I don't really care because I don't see it as a problem.

And another thing that I know RTex likes and I also and it's the Sound..Right Tex
and of course the looks..

Personally I would work on other things first before investing in a new air filter like removing the existing restrictions in the intake such as resonator, larger throttle body, larger intake tube.......less restrictive exhaust

The only thing that is wrong with your reply for him is that it doesn't pertain to his Question YeuEmMaiMai.
But your posting of those tests was well taken on the actual question he asked...

WheelBrokerAng

I got the impression that he talked to his mechanic about performance options or his mechanic saw the aftermarket filter when servicing the car....unfortunately with honda engines there really are not that many gains to be had by trying to mess with the intake and cylander heads already on the engine. HOWEVER WITH THAT SAID you can do some really neat things like swap engine parts around for example H22a head on F motor or 3.5L block with j30a heads and CL-S cams...for some pretty impressive gains.

I am just trying to point him into a direction where he can get some real gains for minimal cost

yea ive got about 260 on my motor and have been running my shorty for about 230k now and my motor runs great, in fact the older and more miles it gets, the meaner she is. it boggles my friends minds when they look at the odo, especially cause they trash their cars every year i guess.

nice...
i hope my 91 accord can get at least that many miles
its currently at 170k

u can get da gay as filters that are track use only cant u which i ges cud be the ones they talkin bout??
