Induction kit leon 1.8T

[Dan K]

Hi I was going to put a k and n induction kit on my leon cupra 1.8t and noticed that there is another pipe connected to the air box.

Can anybody tell me what this pipe actually does. It runs down to the bottom of the engine at the front and it's a circular connection plugging into the air box below the mad sensor.

From what I can remember from when I had the 1.8T - People generally get a small filter for it.

I think that's the SAI, I couldn't tell you what it does but I believe some people remove it so it's not hugely necessary

As for the filter I'd buy a Ramair Cheaper and lifetime warranty and I believe they're dry filters so no issues with MAF's

 

[Dan K]

Ok cheers.

I have a small filter for it

I'm still undecided whether the have a cone or panel filter. Anybody recommend any of these

go for a neuspeed p-flo, awesome gti do one for £136, including full heat sheil and sai filter , top quality too

Id buy a large pipercross filter and one of Richies heatshields save yourself about 40 quid aswell

open cone all day. Great induction sound. Sounds like you have darth vadar in your glovebox

Must say that's the best excuse for buying an induction kit I've ever heard

Anybody recommend a panel filter. Are these any good.

For noise no, For throttle response yes

Cone filter = noise

Panel filter = response

If you want a decent panel filter then go Green Cotton or Jetex

I'd recommend Pipercross but I'm not sure how well they behave with MAF's

 

[Dan K]

Ok brill. So you get better pull off speed from a panel filter.

Does the mpg increase if you have a remap.

 

[googujube]

Youll probably only end up getting a cone filter in the end anyway mate..

 

[markpile]

For me it's panel filter all day long mate my belief is upgrade for that reason not for sound the airbox is a sealed unit which will only draw in cold air a cane filter will at least 70% be sucking in hit air from under the engine bay, even with a shield the induction area is massive and for it work properly you would have to have it perfectly air tight and a ram air pipe to feed the entire surface area of the filter but that's just my opinion of over 20 years molding cars all depends what you want noise or response I personally have do e the n249 full removal and got a cotton green panel on order

As for remap mine is actually better on fuel I've found with most cars after remap designed for your car and a generic one mpg rises I'm getting almost 30mpg round town and that includes driving on boost as well

Yup MPG will increase with a remap because the engine won't be working as hard to get to the same speeds so engine RPM will be lower

However the saying is power corrupts so you'll be gunning it everywhere with a smile on your face so MPG won't exactly be important

I'm guessing you're AUQ lump?

I know where my money'd be going

Might switch back to my pipercross panel mod the airbox and see if i can feel any difference.

Think some on here have even put the cone inside the airbox?

 

[Dan K]

I tried the induction kit and it did fit in my air box without the lid on top but after driving home from work I felt the cone and it was warm so probably was sucking in warm air. I have now removed it and will get the panel filter then a remap.

What is n249 removal.

So green cotton panel filter is the better option you think

 

[Ryan6926]

Green filter is dry so no oil to worry about it

N249's been covered 1000's of times it's in the FAQ's for the best way to explain it

I'd map first before anything else to be honest

You don't buy a cone filter for performance you buy it for the noise

 

[Dan K]

Arh right so a panel filter is more for performance.

Have you any idea how much more horsepower and torque you gain from a map on these motors

I would say cone is better over all on a turbo car. Regardless whether the air is cold is irrelevant. If the air is freezing cold once it goes through the red hot turbo it will turn that into hot air. Turning hot air into cold air is the job of the intercooler.
If running higher than standard power I would say a panel filter inside the standard air box is more restrictive than a free flowing cone filter.

Simple way to test this would be to do a vagcom log on your mass airflow with both cone and panel filters
