Help installing intake? (Melbourne)

[vk]

Hey guys,

Wondering if anyone is experienced with intake installation on a TDI?

And if there's anything to watch out for? ie what to do with the filter, etc? (as i heard not to use oiled ones? i dont even know what mine is.....)


thanks

Sorry to miss your PM's, not on here often.

Installing an intake on a TDI is pretty much identical to a GTI, and it's not a complex thing to do. I'm afraid I don't have a "how to". Perhaps you can ask 42DD, but they can be slack on doing up instructions. Best idea would be to look on youtube for a GTI intake install video, as you have to do is remove the stock intake back to the MAF housing, and then fit the aftermarket one in it's place, it just clips down to the stock factory mounting points, I think you have to swap over the stock box bottom rubbers. The filter element is oiled, and it's ready to go.

Actually here is a somewhat similar intake, doesn't show the standard box coming out, but it does show a similar rubber hose to the MAF housing beside the battery like the 42DD. https://www.youtube.com/watch?v=xEtasrVwN-E

Here is getting the stock box out, only need that part, the rest is all GTI petrol engine specific and you are just mounting onto the MAF beside the battery.https://www.youtube.com/watch?v=CJ_gf_h8j3U

If this is still beyond you, I'd suggest going to a meet night, where lots of guys can help you in person, or finding a good recommended VW mechanic, who could do this pretty easily.

Thanks Greg,

All good, my main question was around the filter? as I thought the oiled filters were not good for our diesel engines...

Should I be using a dry filter?

[Transporter]

The factory filter is very good, not worth of changing for something else. If you go for a wet filter make sure it's oiled properly - not too much, and clean the MAF sensor overtime you remove the air filter.

Well im replacing the whole intake, and the new one uses a K&N cone filter. Which is not dry, and I have heard this is bad for the car? especially diesel, comments?

[Greg Roles]

Load of rubbish, only a problem if you dramatically overoil the filter and some oil gets on the MAF sensor, screwing up that sensor. I ran oiled filters for years with zero drama, just don't go nuts at clean and reoil time. No other issue to a diesel, and this can happen to any car running a hot wire MAF sensor.

Thanks Greg, i accidentally went ahead and ordered a dry pod online, at least this means i can install it at the moment.

So the 42dd filter is all ready to go? what is the recommended clean and re-oil process?

[Ryeman]

Reports I've read say that the standard system actually filters better than the oiled ones.....if filtering is the priority.

[gldgti]

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.

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'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.

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?
