Hey guys can anyone shed some light if I can fit the PI spacer plate and keep the carbon fibre intake box?
Will it shift everything too far to the strut tower and not fit? TIA

1 I don't think it will fit.

2 get rid of it. Sell it and then go pasenger side inlets. Might break even? While you are in there do outlets I guess.

You will not know until you try but the cf box looks nice it is a hindrance for performance

Appreciate the feedback.
Im RHD so cant do relocated inlets and have already done bigger turbos and outlets.
Im running the helix and things seem sweet right but I would prefer PI

Regarding your final point it never hindered the performance, compared it with DCI and no difference....

I was under the understanding that with stock turbos the stock air box becomes a restriction. Maybe your cf intake's airbox is larger than stock with a larger filter?

While I am sure BMS wants to sell inlets there should be gains on stock turbos as shown on the dyno: https://burgertuning.com/products/bms-dual-cone-performance-intake-for-n54-bmw

With inlets, outlets, E85 tune, aftermarket turbos I would think your box would be an even bigger restriction.

As far as fitment I don't think you will know until you try it. Not many people run a CF air intake like yours. Good news is you should be able to sell your PI plate quickly if it does not fit or get rid of the cf intake and keep PI.

The box is a lot bigger than stock, and there aren’t restrictions.
From a performance stand point she has been on the dyno with DCI as that’s what was on her then we changed to the carbon intake and no change, real world change is my intake temps seem lower with the carbon intake.
Running FBO and bigger turbos, we haven’t seen any strict ions with the CF box. I may stick with DI and do Pi when I go RHD single turbo

Just by looking at that picture the filter area is MUCH smaller than DCIs. Wouldn't you agree? While the box is larger I believe filter size is the real restriction. That is why people go with DCI over the stock intake as the panel filter is the restriction. That filter looks smaller than a single cone let alone dual:

But if you are happy with it that is all that matters. My vote is go PI now and run full E85 max out the twins.

I did some comparisons and the inlet hole where the filter sits is over 6” which is bigger than the DCI.
The filter is bigger than one as I got to compare. But the dyno doesn’t lie there was no difference between the two.
We did
DCI
Carbon box lid on and off

So if there was no performance issue I decided to keep the CF box as it so much more aesthetically pleasing. I’ll still run some e85 as I’m currently running the helix OD
E85 isn’t sold here so I have to buy E100 by the drum

How much boost and timing are you running and on what fuel?

I wonder if you just have not seen the restriction yet because of your power level? For instance if you are running a conservative 93 tune w/ upgraded twins you may only be making 500whp peak.

They also made a TB injection plate for E85 iirc. Not sure if many used it though given the price of a spacer and doing it right. No E85 access sucks. I know all about it.
