Air filter after market

[35oz's]

Hi there I was doing some searching about air filters last night and I found someone suggesting a Stillen air induction kit from Tarmac, however no one else had replied so only ones persons suggestion is this a good bit of kit?

 

Can anyone confirm this is the kit here

http://www.tarmacsportz.co.uk/GB/350z_STILLEN_Hi_Flow_Intake_Kit/350Z-402833.aspx

 

Thanks in advance

Probably was me.

From what I've heard it's supposed to be the best induction kit for performance as it is pretty much entirely enclosed (so no heat soak), has a velocity stack ring to increase air flow speed and gives good gains. It's not very loud compared to the JWT pop charger or similar cone induction kits but it is slightly louder than the OEM airbox if you're after a bit more noise.

 

Now I haven't had my Zed on a dyno yet so couldn't really comment on whether some of these claims are true and to be scientific it would need a back to back test against an OEM air box and other kits. In reality you're not really going to gain a lot from just an air induction kit or panel filter anyway.

 

Did you want something just for more noise or where you hoping to get the best performance wise?

[Bems]

As above. If its power increase your after then forget it. You may gain a few HP but you'll never notice it. If its bling then There are better looking and less expensive variants with as good a build quality. Noise wise I hear the JWT pop is a good'un. I personally have the takeda supplied by Tarmac & have to say its a good piece of kit for the money. Looks good, sounds good, fits well and the cone filter itself is maintenance free unlike other filters which need cleaning/oiling regularly.

A bit of both I guess really and some engine bling, plus it's a simple mod that I can do myself it's due for a service very soon and thought rather than always going the OEM route I'd go for something different.

 

Does the kit come with everything you need to fit to an 03 z'd?

[Bems]

Which kit you asking about, the Takeda? Yes if you are. You can also choose between a polished intake pipe or a black one which looks a little more OEM. Mine also came with heat shields but I have the HR engine with twin intakes so not sure if this is the case for the DE. You'd need to ask Tarmac.

Most of the kit's come with everything you will need to fit as Bems mentioned (apart from tools of course ).

 

If you mean my kit ~ The Stillen kit made no mention of fitting the single bolt to the front slam panel so I had to use a spare bolt & JDM washer that I had laying around to do that part. Came with everything else though.

Wasn't the easiest kit to get fitting correctly if I'm honest.

 

With the Takeda I'd PM Tarmac Sportz and ask them the question about the heat shields as I see no mention of them here; http://www.tarmacspo...-Short-Ram.aspx

Could someone explain to me why aftermarket air filters are an advantage over the stock airbox?

 

I'm currently in the process of doing the reverse, and replacing my supposedly better cone filter with a stock 2004 airbox, is it that much a limitation in the combustion process?

 

I'm intrigued, and damn certain that third party companies can't have spent the millions in research and development that Nissan spent when they designed the car?

I believe it allows the engine to breathe easier so more air plus bigger surface area so more dirt gets caught thus cleaner air too

[KyleR]

Stock air box will provide more power than an after market air filter, especially with a high flow panel filter. Cone filters are only for bling or to fit in tight spaces created by the route some FI kits pipe work make.

 

So if you're gonna tune and want the highest numbers, keep the factory box or find a Revup airbox, you can also fit a velocity stack to the OEM '03-'05 box to replicate the Revup, and put a high flow panel filter in.

 

If you want the noise and bling, buy a Takeda, Popcharger or similar, but you will lose a couple of horsepower that you won't even notice.

Your giving Nissan a bit to much credit there. They did starve the front 2 cylinders. I know why but it's still silly.

[Briggsybriggs1]

Iv got the rev up 2006 with the better intake some one on here makes the mod to make the pre 2006 OEM intake to the same as the 2006. That's defo the way to get more power. Iv had intakes on hot hatches and escort RS turbos years ago they made a big difference. But the way the Zs made it makes no increase in bhp just sounds ace :-)

 

Here is the link to the mod

Some of you are saying that these air induction kits make no difference over standard air boxes and although in some cases this may be true, in fact you may even lose power, this is not always the case with every induction kit imo.

 

Now any gains you may get are small and tbh you will not notice any difference imo other than an increase in induction noise but there are still gains to be had over a standard air box & filter.

 

In fact believe it or not some manufacturers do actually test their product against OEM to see what if any difference there is. Again granted these tests are done under the best circumstances for their equipment but still a proven difference from what I have read.

Two examples tested on 2003 Nissan 350Z's;

 

JWT Popcharger with heatshield ~ up to 6.5hp @wheels over standard OEM air box/filter.

Takeda Retain short ram kit ~ up to 19hp/16ft/lbs torque (doesn't say if at the wheels or not) over standard OEM air box/filter.

 

 

Anyway for the gains you may get you're probably better just saving your money & taking a sh*t each time you drive the car just to save weight but each to there own as there's nothing wrong with getting an induction kit just for the look's or sound alone imo if that's your thing.

Not sure what to make of that Dblock as usual your posts are fairly basic.

 

Why didn't you just type "lol" or some rubbish as normal.

 

 

Anyway I'm not saying this is necessarily true but this is what the manufacturers are claiming after their own tests conducted on the Zed. Make of it what you will but for the small gain or loss you may get by fitting an induction kit it's pretty irrelevant tbh apart from they look & sound better than OEM.

[KyleR]

I believe some have been tested here in the UK, I think it was Mark at Abbey who found that they lost power on the standard box.

 

Manufacturers will always talk rediculous gains mouth their product. I think motordyne brag about 25-30hp gain with the spacer it's all rubbish and they do nothing.

 

I posted a video the other day of a test on a turbo Subaru with stock box and filter, stock box and "performance" filter and a high end cone filter. There was ZERO difference between all 3.

 

There was also a test on a tiny sh!tbox diahatsu with a 1300 engine. The stock box smoked the cone filter.

 

So I'm pretty convinced that they do nothing, even on FI which surprised me. They're all bling and sing, nothing else to be gained.

Ohhh tetchy. Just block me if I annoy you that much

 

Put it this way lets say I'm selling a product and want to make it sound good. I might lie or make the testing unfair. There is no way in hell an induction kit makes that much difference at any part of the rev range. Mark @ Abbey has proved it but not just that the zed is notorious for scaling back ANY gains before a remap. A 19bhp WOULD make a difference and I promise you that but there is no way you get that from induction kit on these cars.

 

I agree do it for sound alone. NEVER TRUST their "OWN" biased tests, They wont tell you don't buy this its crap will they.

..But if I blocked you I'd miss out on all your Lol posts.

 

You are totally correct of course. I know manufacturers do tell porkies to sell there products but what I was getting at is just to blanketly state that all induction kits give no gains whatsoever is just a bit unfair.

 

 

Oh and if I had believed the Takeda induction kit claims of 19hp then I would have bought that instead of the Stillen kit I decided on.

[KyleR]

But all induction kits are the same, they are a cone filter either in a box or behind a shield, with or without their own blingy tube. Makes no difference.

 

Sounds like I'm completely against them, but I have the JWT. I bought it for the noise, which is awesome, but now I have a decent exhaust I can't hear it, so I should really put the standard one back in for numbers. However, it looks crap, so JWT is staying, for now

Well what your arguing for! Your so argumentative :p

 

Generally there can be ones that make power but usually they are alot more expensive (not always). Also depends on the original airbox. I don't think the 350z is that bad but in other cars its like a maze for some reason (sound maybe) and replace it for even a cheap open cone will make a world of difference.

 

Also remember like the plenum spacer it can be a 15bhp gain. More like 5bhp and even then its only in the middle part. Doesn't mean your 276 becomes 281.

Not really arguing just exchanging diverging & some opposite views, ...bugger, thinks that's actually the definition of an argument.

 

 

Anyway a good example of the above that you mention is the EP3 Honda Civic Type R as the standard air box isn't very good for airflow ~ in fact there is a mod a lot of owners do called the "Hondata" mod which basically involves just cutting out loads of plastic fins from inside the air box which greatly improves air flow in to the filter & throttle body.

 

Glad we don't have to do that on the Zed standard air box although I did see 14N had turned his old standard air box in to a swiss cheese lookalike in the search for more noise.

[Dblock]

Ahh. I know some of the bigger vtec engines have variable air boxes. The air box is small at low rpm to increase torque but at higher rpm te box opens fully to make it bigger for more bhp.

 

What do the fins in the eP3 do. Are they for sound reduction or cause turbulence?

I found people I spoke to on CTRO all had mixed ideas on that, some say noise reduction others to cause air turbulence but all agreed that the box was more efficient without the fins. You also remove a large section of wall from the box, like below;

And why did they do so? Sorry for the off topic, but I've never heard an answer to that...

It was something to do with of you hit a pedestrian.

I don't see the connection..
