Looking for an Intake [F30/N47/2012/318D]

TormundUK · 09-29-2022, 06:48 AM

Afternoon all,

I have searched lightly for the past couple of months for an intake but to absolutely no avail. Search function here at Bimmerpost arrives at nothing apart from general discussion but no tangible leads.

The only thing remotely close I have seen is an Momentum GT aFe Cold Air Intake for a 320D F30 N47 which has a pretty much identical engine setup.

Posting here is a last resort but Id appreciate any help.

Car Specs:
Country: United Kingdom
Year: 2012
Make & Model: BMW 318D Twinturbo
Engine: N47N

Cheers

For what it's worth, the aFe intake causes boost lag and delays and loss of power. Also the silicone mount to the turbo slips off because it's not a good design. Take note your turbo is different, so the intake mount is a different size.
Stock intake is absolutely the best choice here.

How do you know the intake cause the lag and not other parts?

Because it was swapped back and forth between stock and aFe.

These do not add any power or discernible benefits

You're going to get people saying upgraded intakes aren't going to help, but this is not always true. While 90% of aftermarket intakes tend to create higher IAT's, they benefit greatly from increased airflow from bigger tubing and inlets. The air going in from the intake is getting cooled by the intercooler anyway, so the difference in temperature is marginal. If you look at actual testing and datalogging of intakes, they do provide more power.

Are you aware of any intakes for the 318d? Or should I just upgrade the stock panel filter with an K&N panel filter? Ideally wanted a full airbox cone filter.

dangerus_car · 09-29-2022, 10:43 PM

I am curious as what make the cone filter more effective or better than a panel filter? Any study that states that?

What is your aim with a 'performance intake' on a 318D?

It can't be for sound as you don't wan't more of that diesel rasp, probably not for performance as by itself there won't be any, so just cosmetic?

Don't judge me, but it was indeed for sound, I am however reworking my engine bay with newer aftermarket parts, struts as well as some new OEM parts.

You do realize we're talking about diesels here, which are fuel throttled. The air intake is always open in a diesel. You can add all the extra air you want, but it won't add more fuel. In a diesel, unless the current intake is a limitation to airflow, then a higher flow intake won't make any difference at all.

No worries

For gas cars, I agree, a bit of extra airflow will increase power, because the fueling is strictly tied to how much air there is present.

TormundUK · 10-06-2022, 08:42 AM

As stated, its for sound and engine bay asthetics. I have still been looking. But from the comments, fuck it off entirely?

If you just want sound, I'm pretty sure you can mod your airbox with some extra holes for that.
