Just wondering are they worth the money? Do they make any difference? I'm not as good as I once was........but I'm as good once as I ever was.

A little bit not much.Matched with a performance exhaust then it would/does , see BarryG.Got my ITG for a fiver.

I have an ITG filter, but I had it fitted at the same time as a re-map. The combined difference was very noticeable.
They're not very expensive & have a good reputation, so I'd say buy one.
Allegedly give an extra 5bhp to the TDV6.

Is the K&N filter any good then?

Having had both the ITG and the K&N on various engines my vote goes with the ITG, even when (accidentally), run for way beyond its design mileage the ITG on my D2 flowed well and was in a disgusting state when finally replaced. Bonus is the lack of re-oiling that is required with the K&N....I currently have an ITG on the D3, fitted at the same time as the remap was done by JE. Cheers

K&N filter can cause serious issues with the MAF sensor...at least in older model Discos. I had one in mine until I read stories about that & decided the minuscule benefit I might be getting wasn't worth it. I'm not so good at giving advice...may I offer you a sarcastic comment instead?

Oil on the MAF will kill it over time. Bosch MAFs on VAG and Fiat group cars were / are particularly prone to this. If you ever manage to kill a MAF (or suspect you have) just unplug it (for diagnosis only, NOT a long-term fix!). If the engine performance improves with it unplugged then the MAF is fouled/faulty. The sensor wire can be cleaned with foaming PCB cleaner and a swab, but you need to be careful not to damage the wire. I know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.

Does that much oil come off these filters 
The reason I was getting an itg was that I'd heard that a snorkel can affect the performance because it restricts the airflow so I was trying to compensate for that a bit, can anyone tell me how much the snorkel will affect performance I'm not as good as I once was........but I'm as good once as I ever was.

Oh, dear! 
MAF filter? Min. of Ag. and Fish filter? Keeping cows and cod out of the inlet manifold?
What are you guys on? 
Returning to the subject (note the artful dodging of the word "but" at the start of the sentence  ) - I missed "MAF"s at D3 school - wot is it

As mentioned above, oil fouling can be a problem. It's not just the oil, it's the other contaminants that build up on the oil over time to fry the MAF on some cars. I can't say for certain re. the D3 as I've not fitted a performance filter or had cause to rummage around with the MAF. It may be of a type that isn't so susceptible. I know the Bosch hot-tape MAFs are very prone to this problem but whether the MAF in the D3 is of this type or not? I'm sure someone will be along with the answer to that one any minute now.
As for the chimney (RAI), I haven't noticed any drop in performance from having mine fitted over the last 6 months or so but then I rarely rag it. I may remove it at the weekend and see if there's any change in economy over the following week or so. I know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.

These abrieviations do get a bit confusing, it seems to take more time to find out what they mean than it does to read the mails, but anyway "MAF" is Mass Air-Flow" sensor apparantly, don't know about the cow and cod filters thou' I'm not as good as I once was........but I'm as good once as I ever was.

Sorry 
As above, MAF Mass Air Flow. It measures the volume of air entering the engine and yells at the ECU "More fuel! More fuel!, Less fuel! Steady, steady....." you get the idea. It fits in the trunking after the air filter and is intended for use with a dry filter, hence oiled filters can cause problems if over-oiled as a very fine spray of oil will build up over time on the meter, giving false readings and eventually causing the MAF to fail. I know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.

Hobgoblin, ND,
Thanks for the info. (and the MAFs homework  ). Seems a weird way of detecting airflow... More accurate than a pivoted vane / rotating impeller / calculations I guess. Still seems like a weak spot in a robust system
