Car at an oil change at 9k miles this week. But forgot to ask about getting the air filter done at the same time.
How much are the air filters? Might go down this weekend and buy a new one. Car feels 'stuffy' and less powerful.
Also, any other filters I should change?
Car was on LL but they've now changed it to T+D. Anything else I should have done at the first service?

Order a green cotton filter from jkm stealth. Paper element which aids the intake over standard air filter. £34 from memory.
-
£45 incl VAT from JKM's website. :laugh:
Have been thinking about what T_T said, and it's put me off buying a carbonio + ITG Filter. Buying a new filter every so often seems to make better sense.

What did T_T say about the carbino+filter?

....Following those posts, I had a long chat with the ITG guys including one of their designers. It's late and I can't find my notes right now but it went something along the lines of the ITG being a depth-medium as opposed to a surface-medium (hope I got that the correct way around!) and foam rather than paper. It comes lightly oiled but doesn't need re-oiling for about 60k miles or alternatively can be replaced. The oiliness combined with depth foam results in more particle retention. Maintenance can be simple vacuuming or rolling up any surface crustiness.
Incidentally, they think that the stock airbox is very restrictive and badly positioned from a heat pov.
Although it's what I've got, I don't think that a Carbonio plus ITG is the best solution available but I think it's probably better than stock. Some may disagree but most of the tuners appear to think it's better.

What's the general view on this ?

....To be frank, I find T_T's opinions not 100% reliable - Some are and some aren't. His theory and logic is usually spot-on but doesn't always apply - In My Opinion. But please don't misunderstand me - T_T contributes a lot of good advice and help and always in his truest (and passionate and angry) belief, but....We each have to make up our own minds.
Regarding the ITG filter, the jury is still out as far as I'm concerned, but how come myself and others with ITG filters haven't had any MAF failings? I'll be changing my ITG filter at 60k miles anyway because cleaning it properly is a bit of a hassle. £50 for 60k miles of more efficient air filtration isn't expensive imo.
To anyone who prefers to keep an oem paper filter, I'd say throw it away and replace it at every single service (either 10k or 20k miles).

This is what I was originally going to do when I posted this thread - new filter every 5k, and given the car's just had an oil change at 9k, I figured a new oem filter would be nice as well.
As stated elsewhere, if I could get a nice CAI and fit it myself, without having to take the engine cover off permanently, I'd go for it. Unfortunately all the decent ones have pipes that a baby could crawl through, which means no engine cover!

....Dunno but I guess you're thinking how many you'd need to buy in a 60k mile period - So you can compare costs with an ITG?

Do also remember that the resistance to flow through the oem filter is higher than both an ITG or K&N one. Less intake airflow resistance equates to sharper throttle response and probably the odd extra hp.
-
^^^^
Ah, but technically is that odd extra hp at the flywheel? :evil: :wink:
For what it's worth I definitely felt improved throttle response (unless technically it was the placebo effect).

I have a Pipercross filter ready to go into my 1.4, though mainly for the long life reasons over performance gain. That said, 1.4 naturally aspirated, what performance gain? :tongue:

My car is booked in to get Carbonio CAI + pipecross filter next week . . . . . .

Booked in? The install is very easy to do yourself...
-
SAve the money AlanD and do it yourself.
-
Not paying for fitting ;)
-
:grin:
Let us know how it turns out.
-
Yeah, will do. Got lots of weekend work coming up so its not getting it till the 7th :(

Jesus.....I didnt realise that the government had officially given VW a license to print money :laugh:
Guess I too am now going onto the aftermarket filter route......

I honestly don't know. But that is like asking someone to prove a negative. However, with MAFs, they don't usually fail in the traditonal 'light switch' sense (ie, going from perfectly OK to totaly shagged). Most MAFs with oiled air filters will just get progressively worse - and that actual degridation probably won't actually be detected by the driver of the car. Furthermore, a MAF which is even quite badly oil tarnished usually does not throw an error code, so, technically, when a stealer or whoever plugs in their VAS505* or VAG-COM - then nothing will be picked up. Only through careful data loging, can the MAF be detected as starting to go duff - and how many dub stealers do live data logging?
OH, and I hope you haven't just tempted fate! :lipsrsealed:

Exactly. To correctly clean and correctly re-oil these types of filters is a pain in the ar$e - quite 'labour intensive'.
£50 for 60k miles of more efficient air filtration isn't expensive imo.
But it is NOT more efficient filtration. Granted, your ITG may be very slightly more efficient at allowing a freer flow of air, but I strongly dispute that ANY open-cell type of filter is more efficient at removing contaminents than a paper element filter. And, yes, they are fairly cheap - but I still honestly think that any kind of reduction of filtration efficiency is bad for the long term health of the engine. I've wasted far too many hours of my life rebuilding two stroke engines to know that K&N types of filters really are bad for engines.
ETTO, though.
To anyone who prefers to keep an oem paper filter, I'd say throw it away and replace it at every single service (either 10k or 20k miles).

Very, very sound advice. :afro:

Parts only - £13.10 retail, £7.23 trade - all plus vat.

Well, if you replaced the OEM paper filter every 10k miles, then it is only £72.30. But the manufacturers recommended schedule only calls for the filter element to be replaced every 40k miles - so even if you halfed that to every 20k miles, you would still be up on the ITG - with the guarantee of a healthy engine and a healthy MAF.

But sadly, you forget that all FSI engines are not 'throttled'. :nerd: :smug:
And the standard paper element is NOT restrictive. If it were restrictive, then it would get ripped to shreds, sucked into the engine, burned and spat out the tailpipes as ash! :smug:
If anyone really is desparate to improve on any resistance in the inlet tract, then swap the standard intercooler for an S3 one, or just add a Forge twintercooler.
