Any video links or hints greatly appreciated.
Thanks!

Did you check this video, I'd imagine the process should be similar if not exact?

Yes, thanks watched it a few times however at the 5:45 mark the pipe just jiggles right out. Mine is not coming off. Almost tempted to cut it off it's on there that tight.

You have removed the C-Clamp and cannot squeeze the PCV connector off? From what I’ve seen, it’s easier to remove the C-Clamp, and get some wiggle room to remove the connection by pinching it.

These are a few videos I have been watching to prepare the install… this is one.

Also, take a look at the following video at the 3:58 mark as they remove turbo inlet pipe:

Watch the video above… looks like you need to remove the C-Clamp holding the pipe onto the turbo inlet.

[Ripsin]

Thanks, I'm actually stuck trying to remove the hose that everyone seems to just pull out after loosening the clamp, not the c-clamp on the turbo inlet.

Ahhh, I see. Once you loosen the clamp of the intake tube, you cannot shake it loose? I did see that someone recommended cutting it. I cannot find the video where they did that though.

Here is another video whereby it looks incredibly easy once the clamp you’re referencing is loose… Just need to pull up with a bit of force?

So frustrating mid-install and running into roadblocks. Been there before!

[raannathr333]

I wonder if there are any couplings that are holding the silencer in place that would prevent the lower intake tube from being removed… Just thinking out loud at this point… I’ll be going through this shortly so nice to work through it prior to getting under the hood.

[Ripsin]

Yes, I've twisted and pulled on it but can't get it to budge. Nervous about cutting it since if anything goes south with the install I won't have the OEM to fall back on. Will have another shot at it tomorrow morning. In the meantime thanks for the posts and videos I've been jealous watching these guys just wiggle and pull out the hose, haha.

I did try to remove the valves on the silencer you circled but damn, difficult to remove as well.

One other thing, when you press in the tab on the PCV aren't you supposed to be able to pull it out? That's the other piece not coming out easy.

The video where I mentioned they cut it, they cut the metal clamp, not the actual housing.

You can leave the PCV tubing on the housing as long as it’s disconnected from the top. The whole unit can come out and then switch out the PCV tubing once the turbo inlet pipe is off the vehicle (I believe).

[Ripsin]

I haven't looked at where the PCV connects at the top yet but there's also a very difficult connection left, disconnecting the EVAP line with little space with that hose in place.
It would be nice if Dinan_Engineering made videos for models and showed how to navigate through the difficult steps. Or at.least include instructions with photos of the model engine/vehicle you are purchasing the $$$ parts for.

If you are still having issues after this weekend please give the support folks a call this morning at 1-800-341-5480 and they can assist/walk you through what needs to be done with any problematic parts of the install.

Install was pretty straight forward outside of the two EVAP lines. They’re pretty tough to get off, tougher to get on given the lack of movement in the Crank Case Vent hose… ended up snapping it off while trying to install & line up the turbo inlet pipe, and both connections.

For those that may need the part number for the Vent Hose it is BMW part No. 11157934559. Was an easy fix. And after separating the two connections of the EVAP lines, it was a little less difficult to get on. The trick is you really have to try to line up the two EVAP lines, the turbo inlet, and allow them all to click into place simultaneously, with a little bit of uncomfortable force.

Below is a video with some commentary to supplement the videos already released on intake & turbo inlet pipe installs on the B58 platform with other models.

Pictures too of some spots to pay attention to.

Hopefully it’s helpful. Will get some sound clips up shortly as well.

Cheers.

Sound clips below.

To be fair, the sound clips do not do the drivers experience justice. There’s an added awareness to the turbo spooling up that makes you thoroughly enjoy the sound and moving through the RPM range. This car has the Dinantronics X chip, AA Catted DP, and now the Dinan Intake & Turbo Inlet Pipe. The catted Downpipe gave the car a nice exhaust note…. And the intake & turbo inlet pipe round out to complement the drivers experience. Haven’t dyno’d the car before / after… so cannot comment on power gains. Have noticed a bit of quicker throttle response and pulling through redline nicely.

Definitely throttle response is very much noticed for the good a little bit more slight burbling for the exhaust Definitely pulls better

Absolutely I called the support helpline and was referred back to the instructions as if I didn’t know what I was talking about. Would be nice to see a video of different models instead of just pictures that don’t even refer to the car or you’re working on.

What brand is your catted downpipe?

Active Autowerke Catted DP… picked it up from mike@x-ph.com 💪💪💪. Solid supporter of the community and have helped ensure I’m ordering the right parts every time I’ve work with them.

Wonder if you’d have any knowledge of what the horsepower gain would be if you had a dinan xtronic dinan cold air intake and active autowerks catted dp .

I haven’t dyno’d the combo, so it would be a guess…. I would imagine somewhere around 30-50whp with all three. With a more aggressive tune, you I would expect around 50-80hp out of the engine with intake & catted DP.
