Its probably been covered, I just can't see it for looking. I've just bought the car and love it, just wish there was more induction noise. Question is, are there any gains noticed from replacement panel filters on these engines or do I need a cold air intake type? Also, are K&N as good as they used to be or is there a new front runner in the market?

I have a nearly new pipercross vis carbon kit if your interested....

£240 new

Will sell for £110 posted if you want it

There are no proven gains to either uprating your panel filter OR fitting a CAI kit. These sites and ebay adverts that say you will gain 10bhp or some ludicrous figure are just b*******.

With a turbo the air is being sucked in anyway so there is no need to "force" it in with a CAI kit. The best thing you can do is improve the feed pipe into the standard airbox, or if you are going to fit a CAI kit then you need one with a box around the filter and a good cold air feed pipe - so in effect just a very much more efficient version of your standard airbox. And those cost several hundred pounds... worth it for what is probably at most 5 bhp gain? bearing in mind you could just spend £300 on a remap giving you +30bhp.

CAI kits and panel filters may "feel" slightly different but IMHO that's just your mind trying to justify the extra money you've paid.

If you want to buy the CAI just for the noise then that's fair enough, it's not going to cost much if you get a cheap ebay pipe and stick a decent cone filter on the end of it (maybe £50 at most)

I had a Green panel filter on my VRS but that was just to save on buying a £7 paper filter every year rather than hoping for any performance gain. Had a K&N 57i on my first car (Ford) and it actually lost a couple of horsepower over the standard airbox and filter.

well i fitted an aem induction kit on my mk1 octavia vrs and have a mate with a rolling road, this is an ongoing argument and before the induction kit i had 182.4bhp and with it i had 199.9bhp so they do add bhp

And you'd changed nothing else on the car in the meantime?

And the RR is known as being 100% accurate?

Sorry I find it hard to believe an induction kit can give you a few more bhp, let alone 17... there'd be no point in getting remaps in that case!

they are complete and utter pap - do you not think the r32 and s3 would've come with CAI if they had such good gains?
