I just installed a JDM cold-air intake ('98 Prelude). I'm using the stock air filter until my auto parts store gets in the K&N filter that fits it. But, I've seen K&N's claim that their filters increase horsepower. Really? Has anyone had any experience with a K&N filter actually increasing your car's horsepower? It doesn't seem reasonable to me that a filter could add anything(!).

 

wait are you talking about an aftermarket cone or just replacing the stock FILTER WITH A k&N FILTER?

 

If there are any gains at all, in my opinion they are too insignificant to risk injesting dirt into the engine. "Dirt?" you ask? The suposed gain comes from increased airflow. You can't have a higher airflow through a filter without increasing it's surface area and/or reducing the filtration ability. K&N's website confirms this by admitting their filters filter better the dirtier they get. I would prefer an OEM filter any day of the week and save my engine.

 

well dont they have that rcharge kit?

yes they do

 

No, my JDM is not the one with the cone. It looks like the stock intake, only the center section is a larger box-shape. The filter itself fits inside what looks like the stock filter box, and K&N makes a rectangular-shaped filter for it.

 

it's a type-s intake

there is a slight horsepower gain nothing you can notice, k&n claims you gain gas millege too. but you dont you just save your engine

lucky


i dont see the problem with this. there might be a little gain i mean little but probably nothing noticible.

i dont see how or why k&n would make a filter that would be more of risk putting more dirt into your engine?

 

you gain 2 horses haha, i am serious, you need to change the air fuel mixer (bigger) to gain more for your intake to work at its best.

Air fuel mixer??

Dude, just go, get out, stop posting your BS crap in the prelude forum.

So you guys mean to tell me that my SRI is going to destory my engine. Or are you guys just talking about a specific type of filter?

dude you have no clue what you are talking about

Personally I've used K&N filters in 3 different vehicles for about 8 years now and never had any problems with dust/dirt or the like getting in my intake.

While some people claim they *may* allow more pollutants into the engine, did you ever think maybe it's because roughly 50% more air enters the engine? If more air is entering, then it makes sense more dirt will enter with it.

How about if you're going to make bogus claims you back them up with some evidence?

And you know this how? An engine can still run even if extra dirt and crap is getting in, you'll slowly lose compression due to minuscule scars in the cylinder walls and the valve seats will get scarred as well.

50%? lol

The engine is going to take in a set amount of air at any given rpm, the tiny variations in that are only gonna be caused by the slight increase or decrease in Volumetric Efficiency that you will get from a less restrictive filter.

this whole thread is haha

i say go for the k&n. if you see a lot of "dirt" on the filter jus use the recharge kit plus they got a lifetime warranty

 

mgags7....

I'm afraid 'the voice of reason' is too often lost in the noise of marketing and ignorance. But thanks for trying to keep things on a factual track.

Maybe you should read the links before criticizing my reply. There's more than enough tests of people testing the amount of dirt and such that goes through after market filters compared to OEM, maybe instead of trying to prove me wrong you should go read them, like I did BEFORE I posted, and I even provided a few of them below my post.

I never said dirt didn't harm the engine, I merely stated that in using K&N's over the course of 8 years I've never had any problems with dirt or dust or anything of the like. And yes I have taken off the filter and checked in the tube on my AEM CAI on my lude and it has been very clean, thats after using it for a year and a half

Also sorry by 50% I meant the aftermarkets can have up to 50% more surface area for the air to pass through into the engine, meaning more air (and therefore dust) can get into the engine, not that the engine uses 50% more air.

dude before you start yellin at someone make sure you get your facts right. we're not talking about aftermarket imtake vs oem intake. we are talking about a OEM intake and OEM air filter bs K&n oem replacement filter. No aftermarket involved except the K&n filter.

You mention losing compression, funny. My parents bought a 96 honda passport new from the dealer in 96, in 98 I put a K&N in there instead of the OEM one, I sold it last year and the guy who bought it had a compression test done on it (with 145k miles on it mind you) and he surprised at how great of shape the engine was in, no compression issues at all, or any issues for that matter.

See I do have evidence to backup my claims.

^^^ how is this not OEM vs K&N?
who gives a crap what intake it is, the filter is what the discussion is about and what im talking about.
