Which is the best, Ram air ones (CAIS) or open filtered kits?
Just trying to some research before i splash my cash!!
Do GGR do the same finish as the CR kit, in Carbon?
Cheers lads n lasses

By all accounts the dreamscience induction kit seems to be the best both performance and sound wise. I have a Gen II K&N kit which is o.k but seems to be a bit restrictive with air flow. Go for the dreamscience and you won't be dissapointed.

i have the K&n gen 2 also & i don't find it restrictive
if its a closed cais your after mate, try the autospecialists gen 2 kit. exactly the same as the ggr and code:red, only half the price.

The standard inlet tract is difficult to improve on up to 300bhp or so... provided that you use good quality paper filters.

You get little out of replacing fitting one of these filters performance wise, it is more astetics and possibly sound.

The DCI and K&N GenII ones don't look much in my opinion but as it is an open filterit will likely make a little more noise than the conventional CAIS

Why are some closed and other open, this is decided upon by the location of the filter, the coller the air the more dense it is and therefore more bank, therefore the ones with the filters down behind the fog lights do not need so much of a heatshield but there is a slight increase in risk of water getting sucked into the engine (this happened to a mate in his 306GTI and it killed the engine)

Remember these things are far from cheap (the majority are very overpriced in my opinion)

I note you are looking at a mountune, form what I recall these maps don't like CIAS filters?

Yeah im looking for a mountune during my warrenty period, cuz im getting it done end of feb/early march. Once my warrenty has expired i am tempted by a different map and a CAIS, however im yet to drive a Mountune so like my SIG sez if mountune impress me enough ill stick to it!!

Im jus carbing up some parts of my engine bay and i do like the CR kit aesthetically as well!!
Cheers for all ur input anymore wud be appreciated!

You can definately hear and feel the difference. The CAIS was the very first mod i did so i know that it does give a performance difference. Once a remap and intercooler are added it got better. Now i have the downpipe as well the results are astonishing! I cant fault my cais at all.

Manufacturers dont claim +20ish bhp gain from a cais just for something to type!
If some members believe they do then maybe you should call them and advise them on the sale of goods act. Trust me they do exactly what they claim to do!

+1. the k&n made a hell of a difference to mine. i would liken the standard airbox to running a race whilst breathing through a straw!

Haven't fitted one to my st but all my previous cars have had some kind of aftermarket filter , my 2.0 zetec mrk 1 focus had a pipercross induction filter With a home made heatshield.. It defo made a difference ... Sounded awsome aswell
coupled that to a full stainless exhaust and and upgraded manifold it was a very quick car...

As for price , yeah I agree the ggr and code red are very expensive but plenty of research will hve gone into the design and all claim upwards of an extra 10+ bhp

Even my panel filter and ecu spacer have made a noticable differnce

The dreamscience cais is on my wishlist

Yeah its fine, two brackets give areally strong fix, alteratively spruce it up a bit with an AS ecu cover. Expensive but shiny!

Dsci Induction Kit!
Improves sound 5 fold, and give that little extra across the power band.

Standard DS DSCI brackets are
, in fact the 2nd one doesnt fit properly on mine. You can make it fit though and by all accounts it does the job of holding the ECU in. However it looks
and leave a not too wonderful looking space where the old airbox was.
You dont need to get an ECU cover they are pricey, but does finish it nicely and possibly helps any probs you may get with water and the ECU.

Power improvments? Yes definately feel far more torquey and is nicer to drive. My neighbour said the same thing and I am getting wheelspin with ESP on now
Even my K&N panel filter on a standard car helped the engine slightly (was more responsive down the revs). The induction kit makes a big difference at least on my remapped car. Sounds awesome too. Just get it!!


The comments that the standard airbox is ok for 300bhp is shadey if you ask me! You may make 300bhp on some road somewhere (with how many other mods?
) but it is strangling the engine IMO
