Made a few airbox mods this weekend
I made a few modifications to my air intake this weekend. I needed a new air filter and had a bit of time on my hands so got tinkering. I wasn't doing it for power gains.
It does now have a nicer intake growl and I could say that the throttle response feels snappier, but that could just be me putting my foot down harder to hear the noise. Anyway, I'm happy and that's all that matters New Pipercross filter - A ram air tube into the airbox - The ram air tube goes down beside the front fog light - Inlet for ram air tube - Air scoops - Some holes cut in the airbox to let some sound out (2 vertical rows of holes beside the ram air tube) - |

Two questions here:
What does the ram air tube do, and how hard was it to put in place? and Doesn't drilling the holes in the side defeat the purpose of a sealed cold air intake? |

Euro Airbox - cheaper than the BMW PI, and changing/cleaning the filter with the Euro is much easier as you simply need to remove the top cover - with the BMW PI you still need to remove the entire intake and take the halves apart to change/clean the filter + the PI retains the secondary charcoal filter (unless you dremel it out) while the Euro does not...

I like the secondary air inlet - similar to the Dinan intake mod
I agree the holes drilled in the housing defeat the purpose of a sealed intake and more than likely will allow hot underhood air to enter - that will probably be overcome by the increased volume of fresh air from the 2nd inlet, but you are still losing pressurized intake system by allowing air to bleed out thru those holes... Interested as to what type snorkel you used behind the black grill in the bumper where the hose attaches - or did you mod the original in some way? Did you use 3" dia flex hose, or bigger?

It was a bumper off job to fit it as I wanted the trumpet snorkel to sit behind the grill in the bumper as it looks much neater. It was then bit of a squeeze behind the headlight to get it to enter the airbox. Quote:

There might be an issue here, you need to close out the snorkel inlet or else this is useless cuz alot of air is escaping out from the other end.
This will be nice for engine bay cooling but not intake setup, you want the air to go to the manifold

Hows the pipercross holding up? Any changes after a few miles on it? Just curious too with it being foam would the chances of it getting damp with moisture increase? That version of the pipercross is dry and non oiled correct? Sorry for all the questions lol

Pipercross is holding up well and i'm still enjoying the sound I'm getting. Yes it is a dry foam filter. I have only opened the airbox lid once after fitting it and there was certainly no moisture in it then. I haven't put a huge amount of miles on it as I've been in Chicago with work for the last few weeks (I live in Northern Ireland).
Going back to a previous post, what is the silencer on the intake tube? |

Seems like a clean set-up similar to Dinan. Did you use automotive grade tube? The only negative that I can see is that brake cooling inlet is used but that shouldn't be an issue if you are not tracking. It would be nice if there is a way to utilize the center lower section of the bumper to scoop up additional air to keep the brake cooling intact. Let us know how that filter is holding up after a few K km. |
