Best filter for airflow??

[mattyD]

At the moment I am running a hks mushroom filter but have heard these can be quite restrictive so am looking to get something that would be better for my new setup

Any ideas?

a cut up shiv lol

a cut up shiv lol

Lol there always that!!!..Or the Blitz sus air fliters but they are huge lol

[Lukew360]

I really don't think you'll notice any difference at all mate.

The HKS ones are decent, I would stick with that

[Liam_D]

I have HKS Mushroom and i have no issues with it restricting boost.

[AdamB]

HKS ones are pretty good, but K&N are the best. Lets face it the amount of money they pour into R&D you couldn't compare with others ;)

I can see daylight through my jetex filter

[jakeep82]

im going for just mesh over end of my silicone pipe as i cant find an air filter small enough to fit in i have literally no room !!

[Burny]

No airfilter ftw bit of sieve mesh

[WallaceGlanza]

No airfilter ftw bit of sieve mesh

That can actually be more restrictive, a typical cone filter will have a larger surface area to take in air and with the right design will create a vortex and speed up the air flow.

Apexi are supposedly the best out of the usual Jap filters,

This is true dont the apexi have a small removable velocity stack at the base of the filter?

[Burny]

What rad are you using Matt? I couldnt fit an airfilter on due to the rad being too big

[mattyD]

hmmmmmmmmmmm......................some interesting opinions

I think I will stay clear of the sieve idea though ;) wouldnt mind a bit more filtration than that! lol

and on that note, I think the hks is quite poor for this aswell as any type of performance gain

I am liking the sound of the apexi at the moment

I have a civic rad on at the moment mate, so should be plenty of room in there

[jakeep82]

see i have a half size civic rad but i also have an oil cooler on the other size and my external wastegate is down there too fitting a normal size air filter or is very hard lol!

[Burny]

My turbo had to be filed down so i could get my full size radiator on lol

[LukeSR]

My turbo had to be filed down so i could get my full size radiator on lol

The hell your still using full size rad?

[Burny]

I bought a brand new half size civic one but because i planned on tracking the car i then decided to go for a full size alloy one it 'just' fits haha

I remember coming accoss this, pretty decent http://www.mkiv.com/techarticles/filters_test/2/

[Asad]

Apexi would be the best bet, a genuine one that is...

Id settle for k&n widely avaliable and theres loads of bargains on ebay

Thats awesome mate

with those results it kinda shows that the hks is the worst for both filtration and airflow albeit only 1hp but that could be the difference between 299 and the big 300

I think Apexi is definitely winning the race

[micky boy]

Think td04 glanza has a Apexi air filter for sale Matt not sure if you are after a brand new one like!!!

[Browner]

I run a small K&N filter on my Glanza and rate it very highly. It is a dual feed filter so takes in air from both the front and the sides Of the filter, whereas some filters have a plastic front, blocking airflow in its most direct route, and only taking in air from the sides.

I've had apexi filter on my td04 since fitted and just bought a new one they are awesome, if you are getting a new one mate look at my thread got a brand new one and silicone hose for sale

Watch from 4:26 onwards. Forget the engine as it's an A series, but the principle reamins the same.
