Help installing intake? (Melbourne)

[Greg Roles]

it has been proven numerous times that oiled cotton 'performance' filters dont filter as well as dry paper filters. They do a good job of certain things, not a comprehensive job though. Its simple enough to see why - they flow more when new because they have much larger pores in the filter material - the oil is there to help trap passing particles - but they always have enormously less total area aswell, which means as soon as they become dirty the performance degrades extremely fast. However, its probably not an issue for anyone that spends most of their time driving in 'clean' areas, like around the city.

And then there is the risk of over oiling, which I have seen the results of more than a few times - it can happen pretty easily.

Either way, any airbox mod on a modern golf that isnt pulling over 300hp is really just for the sound fx or underbonnet bling in the end - so as long as it does actually adequately filter your air, then its probably not going to make much difference.

I'd agree on stock paper element vs oiled performance filter, but not dry performance filter vs oiled performance filter. The Apexi dry pod I ran for a while allowed very fine dust through, whereas the oiled K&N kept the intake spotless from what I could observe. I do agree intakes are 99% sound and fuzzy feeling when you pop the bonnet and 1% real power gain. Vraptor wanted sound, and that comes in spades with the bell mouth 42DD.

For the record, this time around I'm leaving the Yeti intake stock, the restriction is the DPF then the turbo.

Is there a good Provent 200 installer in Melbourne - I'm a bit late for the tech stuff.

Mate read the K&N site, I cleaned it when it looked dirty usually at each oil change. As it is very open it gets dirty fast.

I'm back guys.

have been running the 42dd intake with the pro dry s pod filter and it has been great, some awesome intake sound, and a lot of flutter.

BUT, i have noticed that when going slow, and activating the flutter constantly, a strange smell enters the car, and sometimes at night smoke can be seen coming from the filter. I assume this is bad? But i do not know why it is?

Secondly, is it possible to remove the maf grid with this intake?

[Greg Roles]

Yep you can ditch the grid. Smoke and smell is probably oil blowby, some may be escaping from your intake setup, but at idle you may see some blowby escaping from the open filter in the headlights at night. So too any oil in the turbo will make smoke, you always get a bit of oil loss through the turbo bearings. Probably time to take the pipe down to the turbo off and give it a good clean, but be super careful about what you spray into the turbo, as a diesel will run on any sort of volatile, and spraying some carb cleaner in at idle will make it rev out. Take care.

Thanks Greg. The reason I asked about the grid is that the 42dd intake still has a bend in it and I read that the grid was for flow?

Will removing it cause errors?

[Greg Roles]

No, it is there for the sharp 90 degree stock bend, a curve is fine. Go nuts.
