Is it the panel filter or the induction kit:augie

 

[harajack]

The replacement element part no. is E-9251
The induction kit is 57-0125.
Hope this helps.

hello
the filter thats in there is a circurlar one
thanks

I have recently read that oiled air filters like K&N are not compatible with MAF equipped vehicles as they tend to coat the MAF wire with oil over time. I don't know how true this is or otherwise, but given the limited improvement a K&N gives and the number of people who have MAF problems anyway, I'm not sure that I personally would bother.

Stef it sounds like you mean the replacement type that sits inside the existing airbox. The induction type is a cone-shaped filter that sits in the breeze, replacing the airbox altogether.

TERRA - read a few of those too but I don't believe them - frankly you'd have to drown the bloody thing in oil inside and out for it to be an issue.....with the K&N you just wash it in the special cleaner they provide, leave to dry, then spray on the red-coloured oil ON THE OUTSIDE ONLY until its properly coated (colour helps you see where its been put) and thats it - once every 50,000 miles...never had a problem.

Not really - don't take much to upset MAF, ask anyone who's had to replace one.

thanks guys
i will have a think about it ,few other issues to sort first,power steering fluid leak,air con leak, knocking on full lock front passenger side,luckily all under warranty from garage i purchased it from

Yeah but I remain an optimist until I see thread that says "I got oil off MY filter on MY maf"....they're nearly always "I knew someone..." or "My mates cousins best friends motor...".

Since these things are nothing more than a bit of hot wire I'd love to know exactly what the causes of failure are - I suspect its more about the innards than oil on the wire, cos the Hitachi would fail just as often if that were the case.....

hello
whats the benefit of fitting the complete induction kit rather than just changing the filter?

I have done 18k miles on a K&N filter so far , no probs as yet

 

[zippy656]

more bhp and mpg.
but im not sure the £ is worth it.

unless som eone tell me diferent that is

Induction kit is more efficient air routing and thus you may get bit more power and economy out of one.

On the downside you're more likey to get water into the engine as you no longer pick up air from the pocket in the inner wing behind the headlight that stays full of air when you're moving forward even in water over the headlights, whereas the under bonnet area gets splashed with mud and water quite regularly when offroad and on the road too when theres decent puddles around.

As Terra says, the induction kit has much better airflow - basically its a filter that sits in the breeze with a much greater surface area sucking in air than the existing airbox.

As to the induction kit sucking in more water, well I have to disagree with him on that.

Firstly, I've had a K&N induction kit on the wifes truck for about 120,000 miles and never had a problem. Even driving through continental downpours that make the worst of our weather look positively pathetic.

Secondly, the wing area where the standard airbox gets its air from is open to the breeze and just as likely to fill with water as with any other bit of the car, so I don't buy that bit...in fact if you look, the airbox entry point is actually lower than where the induction filter sits.

Thirdly, If you havent got a snorkel, look under your bonnet at where the electrics sit....ok they are fairly well protected but they drown way before the filter gets wet.

Fourthly, the filter sits about a metre above the ground, approximately twice the T2s recommended wading depth....not that we take any notice of that mind you. But think of the potential effect of extremely rapid cooling on your hot turbo for example....not good. If you want to wade anything deeper than a couple of feet, either drive carefully, like I do, or get a snorkel.

Fifthly, I've driven through floods (inadvertantly it has to be said!) that, because of oncoming traffic, have caused a bow wave to completely cover the bonnet for an extended period. Nothing.

Sixthly, these filters are oil-impregnated and microporous, so even if the water got through, unless you are stationary in four feet of the bloody stuff, its only going through in small amounts that won't do any harm (think water injection).

Seventhly, I could go on, but until someone says, "I've got a K&N filter and my engine definitely failed because it sucked water in through it", we're talking conjecture aren't we.

And yes, it makes a noticeable improvement....approx 10% mpg (I went from 23 mpg to 25.5 mpg consistently on my old auto) and therefore pays for itself (£56 or so) in approximately ten tankfuls of diesel, or less if you are lightfooted. Plus a bit of performance improvement as a bonus - not mega but noticeable....

Just get one....:clap:clap:clap:clap

I thought long and hard about which to fit and went for the Induction kit. It is or at least apears to be very good indeed.

I have not come across evidence of water induced problems directly attributable to the K&N. Yes theyve been fitted to units that would have drowned anyway but thats a different set of stories and not mine to tell :lol

Lacroupe explains very well the various different points Ive heard before, particularly the oil/microporous bit that helped me make my mind up in the first instance :thumbs

I phoned K&N re the MAF one. Very polite and helpful bloke who'd heard it all before promised me a no quibble refund if that was the case

Quick, lets open a book on the number of seconds before someone comes along and says "yeah but meantime you've totalled your engine"... :lol

But I suspect the 'heard it all before' reference says it all...:thumbs

So far i've not had a prob with mine but it had covered around 10K when I bought it so it was'nt soaked in oil like a new one. When I fitted one to my old escort I plotted it with paper towel to remove the extra oil:augie
