Panel Filters! Green? Pipercross? K&N?
Which are the best? I heard the Green Filters were better due to being cotton, Although I just found out there is a 3 week waiting list for them, cant decide wether to wait for it or order a Pipercross or K&N? (Could be a waiting list for them for all I know though)
Any advice or oppinions are welcome!!
Cheers

Hi,
I tried panel filters and vauxhalls own and found absolutely no difference in noise or performance.
I then bought one of these....http://www.motor-world.co.uk/show_prod.php?prod_id=7410
The noise they make is very addictive and sound lovely. It is very quiet until you floor it and then it sucks like a prozzy on piece work!
Best of both worlds, quiet if you drive normal and F1 soundtrack if you dont!
Only cost a tenner too!
Matt ;)

Stick with VX own, there the best by far. Lighter on the wallet too.
Only reason for changing would be if "noise" was crucial to you.. :-X :-/

Or Performance
-
I doubt there'd be any improvement in performance with any of them. Unlikely to affect noise as the standard airbox is retained. I thought K&Ns were cotton elements too?
The slight advantage is that these filters are re-useable by cleaning but they require regular cleaning and oiling to maintain efficient filtration whereas the OEM filters you just bin after 20,000 miles and fit a new one. You're unlikely to make your money back any time soon through re-use, however!
On the downside, oiled filters can contaminate the MAF sensor.
I can't really see the point, TBH.
Removing the airbox and fitting a cone filter will get you noise but lose you power due to the fact that they draw in hot air from the engine bay.

.. as an aside, a rolling road day, as is being mooted, would be an ideal opportunity to test some of these items back-to-back to end the speculation.

It doesnt actually with the one i got (one in the pic) , as its a funnel filter so all you need to do is route the pipe from the front grill to sit insde the end of the funnel filter. Then only cold air enters the filter and it gives you the power increase due to better breathing and the noise as the air spins insie the filter.
My partner noticed the gain as soon as she drove it (and she knows absolutely nothing about cars)

:'( Surely there must be some advantage over a standard filter, Wat if my current one is a Halfords own and not Vauxhalls! (I dont have a clue cos not looked though, hehe) The surface area is increased on the green filters for better air induction! there must be some sort of gain otherwise they wouldn't bother selling them!!
:-/
Posted that before previous few posts so just ignore it!!!

Yeah sounds a good idea. Personally i think its more torque than outright power , but saying that it does seem to pick up alot quicker at 130mph on a private road.

There is a difference , honestly , i wouldnt say so if not.
Personally i wouldnt bother with a panel as you are limited by the airbox

Ahh, OK. If you have a sealed duct around the filter leading to a place of coldness that's fine. :y Cooler air is far better than having a little restriction.
My argument is that the original panel filter would have been designed with a fair margin of area in reserve to allow for contamination during the long service life so I'd be surprised if a significant improvement would result over a standard filter regularly changed.

But people sell plastic "superchargers" that are no more than hair dryers that bolt onto your car, all manner of additives and potions, magnets that you put in your tank to save fuel, etc. If people can be convinced to buy them, they'll sell them.

Canceled my order! Not Spending £56 for nothing! Specially if its could cause sensor errors!! :'(
-
Kevin,
Yeah, i spent money on 3 different panel filters and was disapointed everytime. I cant believe something that has the name "maxpower" attatched to it and only costs £9.99 can be so good.
Just goes to show , that price doesnt neccesarily mean performance.

Too true!! Some people will buy anything!!

How easy is this to fit? hose sizes etc. Dont usually trust things that cost so little and Motorworld aint really the most specialised shop!!
No offense intended by the way!! I'm sure it sounds great!! Some pics would be cool of the kit u have and any others people are using!!

Hi,
Very easy to fit. It took me literally 1 minute to remove the airbox and 2 minutes to fit the airfilter. The most time consuming part was routing the pipe from the grill round to go into the end of the funnel filter and stay there. Took about 20 mins or so.
Sounds lovely.
Matt ;)

i have been running a K&N filter for the last 18 months on my Omega.
Last Rolling road we did the car was chucking out 178bhp with the filter being the only mod.
Every other car that day was reading pretty much on the button so it may have made a small difference
cone filters will increase the induction noise, this can have the effect of making the car feel faster that it is actually going
-
I had a K&N panel filter in mine & didn't notice any difference.
I currently have an induction kit & the only difference I can tell is the noise....
-
Normal induction kits will only make an increase in noise and not power due to sucking in hot air from the engine bay.
Funnel filters are different in the fact that they are sealed when the pipe from the grill is over the end. Therefore only letting in cool air from outside and keeping the hot air out.
Its the best of both worlds , a less restrictive airfilter and cold air!

I tried K&N ..Better performance and noise. AND DIRTY AIR FLOW METER !!! :(
better stay away if you are not planning to change the MAF..

what were the side effects of dirty maf?

Your bank balance decreasing by £200...
I see a fair few Omegas, a few with various panels/cones etc. None are actually quicker that the excellent Vx one (huge surface area), most are slower, including those with cold feeds. The noise gives a different impression, but the tests on roads around here show (usually) a small decrease...
-
MAF sensors have sensitive chemical surface..Even used properly, in time will become contaminated by the oil particules in air.
open air filters speed up this reaction..

What would the symptoms be though?
Rough running?

Yes, as ECU will be misfuelling until it decides the MAF is lying (then it will substitute a value, which again won't be ideal feulling by a long shot)

I've had a Green panel filter in mine a few years now. Cheaper than K&N and just as good IMO. I also did not notice much difference, possibly picked up better but that is only subjective.
What did help was adding a second cold air feed to the airbox. Just a few quid for aluminium ducting and a bit of modding. Definately picked up better after that. I'd recommend do this first. There is a How-To over on cavweb.
Since then have 4 bar FPR and filed down some of the lips in the plenum to smooth it off at the same time. Better again. Now picks up so much better than when I first had the car as the power has always been there, just it never felt very "sharp". I must admit I did the cam cover gaskets (leaking) and breathers while I was there so that probably helped a bit too.
