According to that link, the apexi power intake was the best at filtering than the K&N. But in one of the latest Autosalon mags, the K&N was better at filtering than the Apexi Power Intake. I don't what to believe.

Does anyone else have a comment on the stainless mesh?

everyone talks about filtration vs. flow. From personal expreience steel mesch ones have decent flow but in my case shocking filtration.

Id rather more filtration than flow, a restriction of 3kw is better than a stone in a cylinder!

I have always used them and probaly always will, but my cars never see dirt roads, i have also checked comp blades for signs of dusting and even after 50-odd thousand kays never found anything un-toward. Mind you these cars did see quite a few sand traps over the years too :unsure: so if it was going to be a problem i would have experienced it.

mind you there are good mesh filters and there are shit ones.

Wheezy, how could you tell it was bad at filtering? When it was cleaned?

URAS what brand would you recommend for a steel mesh filter? Also since they're a reusable filter, is cleaning them a matter of just rinsing them out?

There will always be those filtration tests. all that I can say is read that test, take it as you will then make up your decisoion.

I will say though that those filters are the highest flowing out of all of them. Undoubtedly. Deosn't matter what the test says.

That test is biased to the apexi filter. I have personall tested some of the filters myself and I have noticed that the apexi filter is MORE restrictive than the hks mushroom pod filters. The stainless ones flow more than the hks mushroom pod.

As flow and filtration are proportional, it goes to say that filtration should be worse on the stainless ones. I personally am not too concerned abobut filtration, but some people are.

I suppose as far filtration goes you only want to keep the big stuff out like bugs and large bits of dust anyway.

all the people in the know in japan have told me the apexi filters are no good. i was shocked the first time I heard it ( i currently have them on 2 of my cars). I then said what is good then? and 2 of the 3 people reccomended the blitz metal ones. if price is any indication the blitz one is nearly 3 times the price (in japan) of the apexi one. The K+N was the one the third guy reccomended. I have always been a big fan of the K+N filters. and If I was going to change it would probably be back to one of those. I've used them before. I've also used the HKS musroom shape ones and they are cheap pieces of cr4p. have a look at any level of motorsport and see how many guys are running K+N filters. It's a lot. especially in the budget teams filtration is just as important as flow and the K+N seems to offer the best compromise.

yeah sucking up small kids is frowned upon.

hahahaha, at least they're returned out the back of the car. What brand do you use? I was thinking of going for a Simota cone pod.

Yeah I use a K&N panel at the moment. I was going to give these stainless ones a shot cos they're affordable and reusable, otherwise I'll be getting a K&N pod.

They seem to be pretty new to the market all these stainless filters yes?

I agree with you mate.

The thing is, a lot of people are happy to run no filter. The way I see it, is i'd prefer not to, in case if large chunks of things, or bits of leaf get sucked in etc. The good thing about the stainless ones, is they would flow basically as much as no filter (minus a tiny bit) and still filter out decent amoutns of stuff. The mesh is very very fine. It would filter big chunks of dust, probably sand, etc etc. Just not the real fine stuff.

I reckon most of us change oil fairly regularly, so i'm not too concerned with filtration. Yes, I know small dust can do damage over time, but hey, how many of us want our engines to last 500 000ks.

kn filters do filter a lot better. So do the apexi ones. But the stainless ones definitely flow more. the question with intake always is AT WHAT FLOW RATE DOES YOUR CURRENT INTAKE BECOME A RESTRICTION. If the kn is not a restriction, even thought he stainless has the capacity to flow more, it won't make anymore power. That's why at low power levels, peopel dont' notice any increase in power with filter upgrades.

It definitely makes it more responsive though (if you hvae a cold air intake too).

When I found chunks of dirt and small rocks in my intake pipe (from AFM to turbo). Although, it came with the car and Im guessing was a no name POS.

Interesting, could depend on what we drive through too and how fine the mesh is I suppose.

i would stay stick with the K+N panel they are good. or if you want some more induction noise (which is fair enough) then I'd give the K+N pod a go. they are cleanable too, and from memory have a warranty of some kind.

I run a stainless mesh filter, with a K&N Filtercharger sock. Looks pretty much like a shower cap. Flow performance is great, though in dusty conditions (grass/dirt motorkhana) the fine dust has shown signs of passing through the filter.

Slightly off track, but has anyone using a K&N ever reported an AFM failure due to contamination of the hot wire by the K&N oil?

i don't use one but having read this i don't think i ever will

I'm happy with my Blitz, love the noise and glad to hear they are one of the best flowing filters.

But if those tests have been done legitimately, the Apexi is far superior - same price, highest performance gain, and best filtering. Doesnt seem right, high performance = high flow, but i thought better filtration would be a trade-off against flow rate. ie, cant have best performance and best filtration at the same time?!

    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
