Just wondering what difference in performance there would be between the green cotton panel filter and green cotton induction kit. I understand that the induction kit would make more noise. Would the panel filter make any real difference and also would they be safe to the MAF?

AFAIK there wont be a great deal of difference, perhaps a couple of BHP at most. And you've probably picked the best make in choosing Green anyway. You're right in thinking that an induction kit will give you more noise, but panel filters usually give better results, especially if you smooth the airbox! And yes the MAF will be unaffected.

Well sounds like you got it all covered.

But the Green Cotton does make the engine breath easier.

Low maintenence.

We sell LOADS of these as these are not greased as much as others so that is why they are not so bad for the MAF

Hi mate....Green Cotton panel....smoothed airbox mod...80mm cold air feed......cheaper, OEM looking/sounding and the same performace, if not better than an induction kit......

Nick

(Think GaryM tested it......Is data logs on the forum somewhere........ and this set up flowed better than the induction kit)

 

[Butcher]

thanks for the responses

what do you sell them for Sarah? there is a seller on ebay doing them for ?45 delivered

 

[JBS-Sales]

?45.80 delivered is the price I can do these for.

You do get a discount and that is included in the price as is VAT and postage.

Not far off am I?

But we are a sponsor of this forum.

Can you tell me more about smooting the airbox?? Im interested!! Already have aperformance filter and also do not want the noise of an induction kit.

 

[bad-vw-boy]

Does the same apply to diesels as apparently they are very suseptebale to air flow changes so should i get a panel or a carbon bmc induction kit?

Read recently an article on a Leon 2.8 V6 (turbo'ed) with 500bhp and still had the stock airbox..so...I guess you don't really need an induction kit...

Anyone know why an induction kit makes the noise, but just replacing with a panel filter doesn't?

Sarah what induction system do you use on the Octavia?

Sarah what induction system do you use on the Octavia?

She's on holiday but AFAIK its an ABD Lan pipe with a Green Cotton cone filter.

I prefer the induction kit, sounds much nicer, and feels more responsive than the green panel filter which I had on before, and they are only an extra ?95.

I guess the question to the noise is that the diverter valve is blowing the air straight into an air filter, whereas with the induction kit, you are blowing it into a great long tube, which has an air filter about 70cm at the end of it, which is bound to resonate and make more noise I guess?

 

[HardeepG]

hmm

I like the noise. The 1.8T is a washing machine (1400 spin) in std mode. But double the price for the noise is offputting. I have petrol to pay for as well!!!

 

[JBS-Sales]

Knew I could rely on you Gary.

Yes we use the LAN pipe and Green Cotton Air Filter at the bottom.

?82.00 fro the Lan and ?45.95 for the Filter.

All + vat.

Just a few problems at the moment with getting the LAN pipes.

That is a laugh , alot of problems.

Hi Sarah,

In your experience, what's the best induction kit / panel filter for a V6 4Motion? I ordered a K&N induction kit only today but am already slightly uneasy about what I've been reading on the forums.

One concern is the oil contamination of the MAF.

The other concern is the noise. I love the sound of the V6 and I thought that the induction kit would enhance it. However, I wouldn't be happy if the car ended up sounding like it was a Honda Civic with a drain-pipe exhaust!

Any guidance would be appreciated.

A replacement panel filter sits in the factory airbox, which is acoustically tuned to suppress engine noise coming out of the throttle body by means of internal baffles, ports, chambers and whatnot. The airbox is a silencer, effectively. Induction kits take this silencer out of the equation, hence the noise - it's not coming from the induction kit as such, the induction kit simply isn't muffling the noise.

The type that is just a cone filter mounted on the throttle body lets out the most noise, and often sounds harsh and metallic. The acoustic damping factor of the filter material is negligible here, you may as well be running the engine with no filter at all. The other type of induction kit, the CAI (Cold Air Intake), or drainpipe with a cone filter on the end (like K&N Typhoon or Carbonio), acts as a resonant chamber for the hard-edged engine noise and makes it deeper and more mellow (until about 5,000 RPM them all hell breaks loose!).
