I don't think that the K&N Kit is available yet for the MY99/00 cars. http://bbs.22b.com/ubb/frown.gif

I run it on my MY97 and have to say it's quality in all depts. finish, performance, sound and VFM.

You best current option is the Pipercross Kit. Jase Cooper has just fitted one to his MY00 and is impressed with it. About 85 i believe.

In my opinion it's not worth paying the extra for the Blitz/HKS kit, which may look slightly better, but how often do you stand admiring the engine bay! http://bbs.22b.com/ubb/wink.gif

I think someone posted on Scoobynet that a K&N kit for the MY99 is due out very soon, (couple of weeks), I have fitted a Blitz induction kit on my MY99,I had the same as you before, standard airbox and ITG, the induction kit seems to allow the engine to rev a bit more freely if that makes sense but the best part is the NOISE. http://bbs.22b.com/ubb/biggrin.gif

Spoke to KN tech dept couple of weeks ago about the 99 kit and they told me that they have stock and that they where only waiting for the go ahead from the parent company in the US to release the kit. They expected to be able release it within two weeks.

I have an email in tonight asking if it has been released yet. Will let you know when i get a reply

K&N is available for MY99 - I was due to have one fitted 3 weeks ago.

Went for Pipercross I.K. in the end but thats a different story....

Spoke to KN Tech dept and sales today regarding the 99 Kit

They said that they are still waiting for approval to release (i think reading between the lines they are waiting for some parts)

They said that it should be released any day and that they would let me know. The part number for the phase two engine is 57-0323.

Gary C who was the supplier that said they had 99 kits avalible ?

A few could get it - Main Subaru dealer being one, it arrived two days after I had my Pipercross fitted there, and they fitted it on another MY99. Also Falkland had them, and Demon Tweeks, where I got my Pipercross from also had them.

BTW in the end I went for Pipercross as a number of people 'in the know' (one being a Subaru Group N 'modifier') recommended them above the K&N. Having seen the two, mine looks to give more 'flow', (and looks good with the chrome). It is a bit louder though. The 'Group N guy' used to fit K&N to the rally spec cars he did, but discovered he got better flow/results from a P/Cross panel filter than a K&N Induction kit. The P/Cross induction kit gives substanially more benefite/flow/whatever than the panel filter, and hence one must deduce an even better advantage over the K&N??

His opinion on the K&N was that it is the Mercedes Benz of the Filter world - good engineering, but you pay for the badge, and can get better performance for less!! - He described the P/Cross as the Impreza of the filter world - no frill, cheaper, very effective!!

If you are bother by potential MAF problems - P/Cross, and K&N (and most I guess) can be run dry, but will need the filter element changing or cleaning every 15000 miles or so. Mine has been very slightly oiled.

As you had the induction kit fitted by a Subaru Main Dealer does that mean that they are willing to over look this when it comes to the warranty as my dealer said 'no way no how if it aint Prodrive your warranty is shot' when i said about an Induction Kit !!!

Thanks for the reply Gary, but i tried to fit a kit supplied by Falkland performance that was listed for 97-99 model and would not fit to my 99 car Maf housing diffrent size to hose and connection plate (Part no. 57-0247). After speaking to KN they said that it was a diffrent kit for post Feb 99 cars (Pt No. 57-0323) which is due for release any time.

Might try the pipercross as KN keep putting the date back and i would like to have it fitted for the Mill lane RR day next weekend.

Andy - that could be the difference, my Pipercross was for Post Feb99 MY99s, the pre-Feb MY99s where a different fit. - But either way - I would go Pipercross - it's definitly out, it definitly works....

Jason - Did I say a Subaru dealer fitted my induction kit?? I must have made a mistake http://bbs.22b.com/ubb/wink.gif no, if its not genuine they won't fit it http://bbs.22b.com/ubb/wink.gif http://bbs.22b.com/ubb/wink.gif However, *a friend* told me http://bbs.22b.com/ubb/wink.gif .....if you ask *the right* service manager, and promise to take it back to him for servicing, and any warrenty work etc then you'll be pleased at the outcome - allegedly, so my friend says http://bbs.22b.com/ubb/wink.gif

I've had my K&N kit for 50,000 miles and it just gets better! http://bbs.22b.com/ubb/smile.gif
It only needs cleaning every 100,000 miles or so, and the noise is much more discreet than the PiperCross Vector Power Cone.
My friend's just bought one for his car, and it sounds very 'dump valvey'!
How can you say you pay for the name with K&N when it costs no more than the PX?? http://bbs.22b.com/ubb/confused.gif
My advice is to go in a car with both fitted and see which you prefer.
In a recent Jap test, the K&N came second only to the Apexi kit, and above the HKS and Blitz offerings.
Personally, I would wait for the K&N kit.
You won't be disappointed.

If K&N kit offers less performance than an equally priced Pipercross kit - you are paying for the name.....? http://bbs.22b.com/ubb/wink.gif

9th April 2000, 17:41
I will put money on it that the K&N is at least as good as the PX in terms of performance increase, if not better! http://bbs.22b.com/ubb/biggrin.gif

Like you I only have personal experience of one induction kit - As I said, the main info I had was from a preparer of Group N Imprezas (TAS in Leyland) who found a PX panel filter offered greater flow/BHP increase than a K&N induction kit, and that the PX induction kit will offer even further gains than the panel filter. He/they were the ones who said you pay for the K&N name. I am sure it wasn't aimed as a personal swipe at K&N or their customers. http://bbs.22b.com/ubb/smile.gif

I took the advice, and from experiance so far, the PX does give an impressive performance benefit, and certainly more than I had expected having read others experiences having fitted induction kits (K&N, Blitz etc).

You are right about the noise - it is more intrusive than other kits, but Greater 'flow' will lead to more noise. If that is a factor then probably K&N or Blitz are the better options, if on the other hand performance is the primary aim PX will give greater gains (IMO & that of TAS).

Each to their own - pays your money....etc http://bbs.22b.com/ubb/wink.gif

How much noiser is the PiperCross than the K&N? Want better breathing but don't really want the sound. Can you quantify the difference?

12th April 2000, 12:39
If you don't want sound - don't go for Pipercross - I will be the first to say it is audible in the car, but still queiter than my exhaust (Prodrive Back box + Straight through centre). Only really intrusive between 3-3750 rpm, and obviously inaudible when off boost, but you can certainly hear it above say 3k rpm.

I'm in Preston if you want to hear mine.

13th April 2000, 00:31
The K&N makes a far more discreet noise than most other kits, and I for one prefer it. You can hear it in the car, but it complements the exhaust perfectly.

They don't take long to fit.....perhaps at the next dyno day I can swap mine for someone's PX to see! http://bbs.22b.com/ubb/smile.gif


13th April 2000, 07:09
Definitly worth doing - you might even persuade PX themselves (or a supplier) to give/lend you one for a dyno day for 'controlled comparison'. - but don't lose sleep over it http://bbs.22b.com/ubb/wink.gif
