Green Filter or K&N ??

[Noloc]

Alright... since I just purchased my 2004 4Runner I don't want to go crazy with the engine mods yet ( at least until the supercharger for the 4.0L comes out) but I want to change the air filter. So I come down to two drop in choices

1. K&N 33-2281
or
2. Green Filter

Any experiences?? Any recommendations??

good ol stock filter works the best

Really?

Really??? I'm not expecting enormous gains but I know when I put a K&N in my previous car (2000 Solara SE V6) I did get better gas mileage. I can't imagine that the stock filter would out perform a K&N or even a Green Filter at that. Is this based on experience??

I read on internet that amsoil air filter traps more dirt than K&N. I haven't tried neither of them. But planning to install one of them.

well you just have to look at it in a simple state:

you have a stock air filter that filters out bad components. now if you want high performance stuff, what do you need? More air! more air means that the filter has to be able to take in more air right? well it's not like the filter box will get bigger so that means they gotta change the particle size that'll suck up air. this means in the end it'll take in more bad stuff.

if you're doing lots of performance racing (i.e. track/strip/whatever), those conditions are ideal for performance filters, it's clean and it doesn't matter if the intake takes in a few particles so no biggie. they'll just tear the block down and clean it after.

unfortunately, we don't have that luxury so ultimately these filters do more harm than good on the long run I think. keep in mind that this is just my opinion so... plus not like the air filter is gonna give up 50 hp anyway. 1-2hp? damn I wouldn't even know the difference...

i'd much rather just hose my stock filter down and do a quick clean and call it a day. saves me $$ and I can use that for other mods. Some mods for air intake to look into are the deckplate mod that alot of the toyota community does (tacoma/4runner/tundra). search that as I'm vouch for that than an airfilter.

good luck

I'd have to agree.....i tried a k/n filter charger on my 3.slow, no noticeable diffence except noise....cleaned and re-oiled the thing once, but noticed when holding filter up to light, could see tons of little pinholes, plus it was a messy deal with oil........went back to stock and havent looked back.....Just my .02

Not really true, thats why the filters are oiled, it's the oil that traps the dirt plus the more dirt it traps the better it filters.

I put a K&N on my Dodge at around 40k, I've got 210k on it right now and I've driven it off road and in very dusty conditions. I've cleaned it proably 5 times over the years and it hasn't let me down. When I tear the engine apart at 300k I'll let you know what it looks like inside.

You hose down your stock paper filter? How does that work for you... suprised it hasn't disentrigrated yet. Thats another reason off roaders use a cotton/oiled filter... it holds up better to water conditions where a paper filter will fail.

Whats the average paper filter cost these days? $6-10? So a $50 will pay for itself in what would normally be 5-8 filter changes (20 - 30k).

hose as in air compressor hose... no water btw. also where I live, we don't get much rain so I have no worries about water conditions damaging my filter

I've done the oil filters... just such a pain ... not like you gain significant amount of hp that will help. if you oil too much it'll suck it up, if oil too little it does no justice... blah...

but if ya have the funds to burn, by all means go with the Amsoil instead!

Ahh ok, that makes more sense (blow air).

I agrees the oil filters have their ups and downs. I found the easiest way to oil my K&N was to use the aerosol spray, doesn't make a mess like the squeeze bottle does.

Use the exisisting Stock filter for a while?

I got my new K&N today....but the question is;

Do I at least use my factory filter with only 400 miles on it, until it gets a little dirty?

Or do I toss it, expecting the K&N to give me a little more power, or mileage?

If you're gonna toss your factory filter, you think I can get it from ya? I could always use a stock filter
