Which is better performance panel Air-filter. A K&N. Or a Pipercross ?

Difference is minimal, even to a stock paper filter, any difference you notice is a placebo. 

 

Also be careful when you clean it and re-oil it. Excess oil will end up coating various air intake sensors and throw off their readings. 

Bmc or itg are top end 

Clean OEM filter. A happy medium between airflow and filtration. 

 

For best outright airflow BMC are meant to be the great but are also the most expensive. 

 

I fitted a Revo one (similar to Pipercross, possibly same) to a remapped Leon FR TDI and noticed nothing at all.  Though Revo said the differences are more tangible on the TSI’s.

 

But having spent many many many hours online searching for any conclusive ‘evidence’; I ended up getting an OEM Mann filter with the obligatory 40% off from Euro Car Parts.  If swapped every 10k miles I’m sure it will be just as good as anything else (it was £10)

Have an Airtec foam cone filter with heat shield and red larger induction pipe which is part of the kit. About £300 fitted and sounds great. Must work as my 245 is probably the most powerful in the UK with a stock turbo.

Is it? 

 

You should have mentioned it sooner

Should I ask why a Superb owner is giving advice on the Octavia Mk3 section?

On a more serious note having mapped the standard 2.0TDi engine on a 63 plate Octavia Mk3 all I did was keep the standard airbox and used a Golf Mk7 K & N Filter (about £50) which gave and increase from 147bhp to 186bhp and torque went up from (standard is 236lb/ft) 246 to 317lb/ft.

I went for the APR carbon fibre intake system when I first got the car, and made a genuinely noticeable difference on pick-up than the stock setup. Admittedly, some of this could be attributed to the engine 'opening up' within the first 2000-4000 miles, but it made me smile a lot more so meh. However, what reduced the smile somewhat was that it cost a disgusting amount of money - especially when I found out that Carbonio do it about £200 cheaper . Depends if you're looking for a filter-only, rather than intake system. 

Just change the paper one every 12 months or 15k miles and save your money?

Such as an M badge on the back of their 320D.

Indeed Or  a vrs badge on their ps130/pd170 etc etc

 

Marketing is great...

 

Serious point though, regularly changed paper filter will filter well, not restrict airflow significantly and more importantly has no risk of contamination of MAF from over oiling certain filters.

have a look on Darkside developements page, they did a test and actually found that the stock OEM part is very good at flowing air, they also go on to show that the oil covered air filters kill mafs. This is not a new concept as when i had 400bhp scooby i had to get the maf deleted as it was a part that was forever failing when you an a cone filter ETC.

Funny that. A huge OEM with vast resources at their disposal; design, test and tune their components to be efficient. 

Meanwhile an aftermarket company welds a maf mount to a aluminium tube, sticks a cone or a sponge on the end and goes £300 please. 

 

Does it make a difference, some say yes.

Are they not diesel specialists?

They are but there are many other videos on youtube that show similar results. The problem is its hard to distinguish which are genuine and which are paid to give good reviews.

 

Like i said i ran an open cone on the scoob but ran a seperate cold air feed to prevent heat soak ( alot of the more expensive kits come with heat shields) and had the maf deleted.

So the science says the more you spend on an air filter to more power and torque and better acceleration you will get, even without a remap. K & N gained 4.3bhp the most on test.

I have had no issues with the mass air flow sensor but my induction kit came with a metal heatshield. The OP's question was Pipercross or K & N and having used both I don't think there is much between them apart from Pipercross slightly cheaper.

From this article:

The first thing to note is just how incredibly restrictive the standard airbox setup is. The engine is effectively being strangled with the standard airbox fitted, therefore the best thing you can do to a Fiesta ST, and indeed many other cars, is get rid of it and fit a less restrictive cone filter

 

When you hear them talking about the engine "pulling air through the filter" you know straight away that the physics is beyond them.

 

It is atmospheric pressure that pushes the air through the filter, guess what variable they did not measure and ensure was constant in all of the tests? You got it, atmospheric pressure.

 

To paraphrase my dear departed father "I bet you a pound to a piece of ****" that the K&N filter tests were done either on another day or at a different time of the day.

These performance filters are less restrictive and can improve mpg and acceleration (slightly), but do cost more and need to be kept in good condition.

I use Pipercross myself because no oiling necessary and can be washed and dried if it gets real dirty. 

I have noticed better mpg since I put it in. But if you don't want to believe me try this report in an actual scientific journal.

 

From the paper:

Conslusion ... The fuel economy tests shows that K&N air filter provides a better fuel economy compared to OEM style paper filter in both new and clogged condition. The acceleration tests also shows that acceleration times for K&N was slightly lower than OEM style paper filter in both new and clogged condition.

So back to the original question ... Pipercross for me every time. Running one in both my Fabia mk1 VRS and my Octavia 2.0 TDI (150bhp)

But the PiperCross, K&N, GreenCotton or what ever needs to be clean.

 

So maybe for 10,000 miles it is all good, first time cleaned all good, come time just a dirty Air filter.

Some are great when H20 would turn OEM filters to pulp,  or dust / dross is an issue and cleaning filters is part of regular maintenance.

 

Police Vehicles might get K&N Filters fitted, at Tax Payers expense, but then they get changed and binned, not cleaned and recoated as someone using them as a long term filter might do to be economic using a Long Life Filter.

No performance improvement if the filter is just making the car use more fuel without the car breathing better....
