Hi guys can anyone help,

I've heard that the K&N 57s kit puts the diesel into limp mode, is this right? Reading on other sites they are recommending the Pipercross PX1746.

Anyone have any of these fitted to there diesel ST's?

Pro's & Con's?

Thanks in advance.

HI,

I fitted my ST with the Pipercross and no issues. Cant say I notice a great difference, but at least not having to change filter now. I also fitted induction hose (Mountune), nice little touch.

I want to save the trees.

Paper comes from trees hahahahha

So i can wash it, you cant wash a paper filter lol :)

Using paper is better for the environment and the cost is negotiable, about £7 every other year.

I was truly not having a anti deisel post and I did not take @Adam-ST3 post as one either, it is a valid point.

Yes petrol owners may increase their performance from the standard 250 horses but, if increasing performance/modifying is your thing surely it makes sense to start at the front rather than quite a way further back without ever getting to where you could have started if you had just bought the petrol.

You could now argue the petrol guys should go RS then and yes if you are buying today and willing to twiddle your thumbs for 12+ months you could have a point, but i doubt many have that luxury

To conclude please don't turn this in to a deisel defensive thread be better than that, mod you deisel.

Speak to arun882 he has the pipercross and it went into limp mode on the motorway the other week just lost all power.
It went into limp home mode once, but hasn't done it since. I reckon the filter on its own will be fine, and that I'm probably pushing it a bit by also using a RS airbox

I also found disconnecting the battery for 15 mins helped

Someone has nicked your number plate.

Not sure why you would change the filter on a deisel (genuine point not having a pop at deisels)
just looking at this,also an aftermarket filter has no use whatso ever on a derv,they run so cool and efficiently,no gains to be had(fact)im just sayin like and not winding anyone up. :brow:

i got a K&N filter free when i bought my blufin from demon tweeks

its run fine for over a month now.
How is this running now?

After so many saying that the K&N sends the car into limp mode, I was considering to leave it, but I have had K&N filters in my last 4 Fords... I'm compelled to buy another, or remove the one in my current car before I sell it, and use the K&N for my soon to come ST Diesel...
