K&N Filter -searched

[MoldySpore]

So after researching, basically people think the FILTER on weapon-R intakes/CAI are the bad part. So what filter should I put on it if i get it? Should I go with K&N or someone else? A link or a name of the filter would be nice since im total noob when it comes to intake related stuff.

Also, doesn't changing the filter on a Weapon-R intake make it so you can't get the RAM air hose extension or the heat shield from weapon-R (making it a cold ram air intake)?

Thanks guys

if you actually get a weaponR intake, I think you may be right, and you won't be able to get another filter since they have that fancy shield over it, etc...

but if you get a cai, your best choice would be to get a K&N intake, and get the biggest one you can find with a 3" inlet the larger the diameter of the filter, the more air you'll suck in....longer ones don't make a diff

I'll be honest. Get the cheapest one you can buy. I bought a K&N, and they're all over-rated.

the only reason to buy a K&N is because youll know the quality will be good... if you can go and get a hands on on other cotton gauze filters.. just get any that are rigid enough... cheap ones have thin metal gauze that bends and gets sucked in.

cotton is cotton.. they all filter the same, in the same condition. its just the rest of the filter structure that you gotta look out for.

I had a K&N drop-in replacement and got rid of it for an Amsoil drop-in foam filter. The Amsoil costs less and I get 1 - 2 mpg more than I did with the K&N. Here's the link to their application guide:

i fail to see how you could accurately measure a 1-2mpg increase... it could just be teh weather.. but i belive ya... good foam filters are better then cotton anyway.

Also I believe TRD makes a preformance filter for the Camry.

ok. that kinda sucks since you can't replace the filter and still get the hose extension to make it a CAI.

A lot of people say that Injen is the way to go but honestly i don't see it being any better than a Weapon-R intake. ESPECIALLY since the WEapon-R can be found for under $110, and Injen the lowest Ive seen is $185. And thats just the short ram.

Why is a foam filter bad? Is is just because they dirtty quickly/clog up? Wouldn't it be about the same price to replace the foam filters, since they are cheaper, say twice a year instead of replacing a, say, K&N just once? Or is it more of a air ratio thing (meaning the K&N provides more performance)?

[terrastrife]

good foam filters are the best ofr performance and filtrations.. but the thing is.. shit fom filters you may as well put a house hold sponge there instead.

foam isnt washable like cotton is. with the same replcement cycle, a re oil (for cotton) will cost about 1/3rd the price of a replccement foam insert.

actually, best filteration is paper, but it doesn't flow as well as foam or gauze. Not a big fan of foam myself but I also smoke, drink and chase tail. I currently run a K&N and with no service for 8K miles. I will look this weekend to see what is coating the inside of my intakes.

[MoldySpore]

are "bad" foam filters just filters that let a lot of crap into your engine? or is it a performance issue?

why are the dragon filters considered to be so bad by so many?

its just a rebadged k&n filter - and trd only makes drop-in filters



and when it comes to drop in filters, k&n/trd is the same as no filter on the dyno, so it doesn't get any better than that

I would presume that the cone filters would be identical since the filter design is the same

Paper are diposables. They tend to clog up and if they get wet, kill flow.
Gauze are reusable but they do need to be cleaned. K&N sells a kit for clean and reoil. I keep a paper filter to use when I clean my k&n.
Foam tends to trap dirt deep in itself, real hard to clean well.
Both foam and gauze need oiling.

Dragon are short air intakes that use a foam filter.

Here's an interesting write-up:

Looks like I'll get the Apex'i for my Supra, if and when I actually buy the Supra.

differennces in all decent air filters are down to engine running time, air temp etc.. a 1C difference in air temp/2-3 minutes engine running time can see 2-3kw difference easy.

unless youre boosted, the stock paper filter has enough filtration and throughput for a stock or mild engine.
