K & N or not?

[sanct]

I know this topic has been tossed around for a while but I have a main service coming up very soon and feel like treating her with a K&N panel filter. Can we have a vote on who thinks it's a good/bad idea.
You decide............... Yes.......... or No...............
Cast your votes now!

If yes wins where's the best place to retreive one?

Did you notice a performance improvement or change in induction noise?

[ANTHONY]

a Little bit but hardly noticeable

So these k&n panels can be cleaned (with a cleaning kit) and reused, how offern do you guys, with them, clean them? And whats the oil for in the cleaning kit?

And is anyone who uses the BMC filter panels? am I right in saying their not reusable?

I'm not a fan of other filters, K&N or not. The air filter is there for a reason - to keep a lot of airborne cr@p out of your very expensive engine. If you put a more free-flow filter in, it allows bigger particles of cr@p into your engine which can not be a good idea.

Other people like to install mushroom filters instead of the original. These, by virtue of their design, draw hot air from inside the engine bay rather than cold air from outside. Given that more power is obtained from a colder petrol/air mixture, there's no sense in warming that mixture up by drawing in hot air - it can only result in a reduction of power.

If you do choose to install a replacement filter, do not install a "wet" filter (i.e. one which needs to be oiled first) - you will destroy your air flow sensor which, apart from the expense of replaceing it, will seriously reduce your power, most likely putting your engine into "safe" mode.

Have I put you off the idea yet? ;)

But surely these manufactures of performance air filters know about that and have accounted for it in design/production?

Well yes.. lol
I just remember the heady days of instaling a K&N filter on my mini and grinning as the induction virtually sucked your dash in :)
The 'ol day of glory

The air filter fitted to the car is not the best they could have fitted. The reason for this is simple - cost. Easy to manufacture and mass produce...

If they fitted every car with the optimum components, then the cost would then be passed on to the consumer. This is the reason why Porsches, Ferraris, Zondas etc are so expensive because they use the best materials and the cost of R&D associated with developing the products is very high.

I agree that the use of a mushroom filter is not recommended in VR-4 due to the high temperatures under the hood. I have installed a K&N panel filter yesterday so still draw air from the outside using the standard air box. I have noticed a mild change in the car. I wouldn't say performance has increased but throttle response, power delivery and fuel economy have definitely improved.

K&N are the world's leading manufacturer of a variety of filtration products - most especially air filters. Their position in the market should speak volumes for the quality of the product they manufacture. In all the cars that I have fitted a K&N filter to I have never yet had any engine trouble and I lived in a hot and dusty environment in South Africa...

K&N's biggest export market? U.K., Germany and Australia.

That's the end of my story.

[stuey]

Whilst I agree with the'theory' that oiled re-usable hi-flow filters may not be ideal, I have used K&N filters in most of my cars over the years with no problems.
They are a huge company that I would think to think has spent some money on research & development so would know a thing about induction air flow.
I didn't know you could get them for VR4's...

i found i got a little bit more power at the top end.

with the oil being bad - just dont over oil it!!!!!

[bernmc]

Read this thread (http://www.clubvr4.com/forum/showthread.php?t=14349). Then buy a decent filter - not a K&N!.

[ANTHONY]

sp apart from a standard mitzi or a K&N what other panel filter are there out there

Iv seen BMC (http://www.europerformance.co.uk/pages/products/product_info.mhtml?id=501296) & Pipercross (http://www.europerformance.co.uk/pages/products/product_info.mhtml?id=3661912) panel air filters on the market but dont see why these would be better then k&n..

[suttonp2]

Hi there, I've got one of those green HKS mushroom type filters and the general consensus is that it's filtration properties aren't great, plus as mentioned, it's just sucking in warm air from the engine bay. Basically I'd like to go back to the standard airbox but I didn't get it when I bought the car, does anyone know where I could pick one up for a pre-facelift Leggie??

Cheers in advance

[unclepete]

suttonp2: Dick Barton got one from Mo (I think his username is zeddy1?). I have his mobile number if you want it. He's based in Blackburn but sent one up to Dick in Scotland so no problem wherever you live.

[suttonp2]

Thanks UnclePete, that'd be great! If you PM me his number I'll give him a call.

Thanks again!

Ive had A BMC panel and Was told they're cleanable. I'd also like to point out that just because K&N has a huge marketshare this should in no way indicate their performance or quality, just think about microsoft for a sec. I'd go K&N next time personally as they're a fair bit cheaper than BMC, for most likely very little performance difference.

[jerryd_33]

Anyone thought about them?

The " STAINLESS STEEL " mesh ones.

The " BLING " effect in the engine bay area is worth it. Plus and this is definitely worth it, you can wash it in " HOT WATER & FAIRY LIQUID "

I have changed my HKS to a Blitz. Performance, cannot say any increase but sound effect.................YES!!!!!!!!!!!!!! COMPRESSOR HOWL!!!!!!!!!!!!!!!!!!!!

[kamal]

Worth looking hear if your considering buying an aftermarket filter:

I've got a panel filter you can have for a small consideration + postage. I think it is K&N, if you are interested I will venture out to the garage and check
