Hello To you all

Hoping that some one can help.

I have a 20V turbo fiat coupe and recently fitted a K&N cone filter; however, the only thing it did is made my car run like a sack of poo.

As soon as you floored the car the turbo seemed not to be creating as mush push as with the standard air filter. That was the main problem I kept it on for an hour or so to see if that made a difference but it did not.

As soon as I put the standard filter and box on it was, all back to normal push you back in your seat acceleration.:slayer:

Does anyone have an explanation for this.

Thanks

Where did you fit the cone? If it was sucking in hot air that could explain the loss of power.

I wouldn't fit a cone at all on the 20v Turbo Coupe. It is bound to give you trouble.

Your car just doesn't like the cone then, drop a panel filter in the standard airbox instead. Most coops (mine included) lose a little low-down torque and gain it top-end.

When you fit the K+N cone and drive it for the 1st time it is disappointing - that kick in the back has gone and the car seems slower, yes?

It isnt but you lose a little torque lower down and get more higher up the range - the car is acting as it should with a k+N cone fitted. One bad thing with them is that they are oiled and therefore the induction pulls that oil through your maf sensor and will coat it - shouldnt cause massive problems but obviously it isnt how things should be. Dont touch or attempt to clean the sensor btw!!!!

Alot of people use the Apexi cone filter - it is dry and is highly rated by many coupe modders.

The K+N sounds nice though

Another vote for the Apexi - I sold the K+N a couple of years back. Too many "it's fccucked my MAF sensor" posts.

Thank you for all your replys.

Thanks

you should spray the MAF with contact cleaner every service (£3 per can at maplins), its amazing what a difference it can make. the same applies to every car with a MAF.

you shouldnt oil a filter on a car with a MAF, you can burn the maf out, or at least cover it in oil causing underfueling.

I remember when I was getting my car mapped the guy from angel scotland said using oiled filters with a maf sensor if fine. Aslong as after cleaning the filter and oiling it you remove the maf and plug the hole and run the car for a few miles after, then simply put the maf back in.

I wonder where people get these horror stories from oiled cotton gauze filters?

Nobody has been able to prove this ever. K&N made a test with a heavily over oiled filter and pumping for 24 hours 1,000 cubic feet of air through it into a particle collector. The traces of oil where not enough to coat the actual sensor (not the housing).

The only problem I know with oiling in my over 25 years in the field when engine oil was pushed back from the breather (in turbo applications) or when people used oil based liquids when maintenance work was done.

Having just taken my maf and cone off the car - fitting a straight induction pipe - I can safely say that the inside of the housing and the sensor were dripping in the oil from the cone - that said, I havent experienced any running problems on both coupes, both of which have the K+N cone.

perhaps then the problem lies with re-oiling the filter too much? regardless, it makes more sense to just go for a dry-type anyway, just in case

have a look at this

i had the same problem lack of low power but have left it on and have got used to it now , but thanks to everyone who commented as i explained the problem to me

I'm running a K&N 57i kit and do not have any loss in power.

There isn't enough oil on a cone filter no matter how big to see something like you describe unless you dropped the whole car in an oil tank.

Heh Oldschool, I was just coming on to eat my hat - as I say I have just been fitting my straight induction pipe and explored the oil thing a little further.

:worship: I would conceed and agree with you that it isnt infact the cone oil. The pipe, maf to cone, was bone dry but the sensor housing had oil in it - having explored the oil some more I know it now not to be the cone oil and therefore stand corrected.

Always good to learn something new and proves there is always more than one opinion and never take just one opinion as gospel.

Now on with chewing my hat... :yuck:

after having a slight low down power loss from installing a 57i , i have just installed my gtec 1 from graham of ebay and the car is flying now , i,m glad i left it on coz the noise from it now is SUPER LOUD . next is a frount mount intercooler and larger turbo ...........

I've heard of oil affecting the MAF sensors when K&N panel filters are fitted, but not induction filters.

Maybe there's some mix-up between the two?

Have missed this post previously. Have to say that I will pull my hat when I see you next time as there are not many people who humbly admit when they are wrong.:worship:

It is claimed by many people but so far nobody came up with any evidence. To the contrary it is proven that it is not possible to over oil the filter that much un less you put a bucket load of oil on the filter.
