Well the first carbon piece has been made.Unfortunatly not perfect but i'll change a few things to get that solved in the future.I also found out the front support beam which blocks most of the air coming in is different between Sedan/coupe and the hatches.The hatch support beam has a extra lip with 2 holes right where the airduct sits. There's also a big price difference between the 2 the hatch ones are around $90 where as the sedan/coupe ones are around $30 .
I'm looking for a used one local and i might buy a hatch one and see if it also fits the sedan which i think it does.
The hatch one does not fit with the current lower airduct as it has the extra lip on it.
Why does the hatch one has that extra lip?Don't know yet ,but i'm thinking it's something from the Type R as the part number uses TGG and that's mostly used on type R parts.
I cannot find any parts that might go into those holes.

As for the part that blocks air i think the best option here would be to drill holes in it .
For airflow it is better to completely remove it ,but the support beam would have a weak spot there and might bend over time.

That's bad news for the Hatch crew.

Yes it might be , but that lip could easily be removed without changing the strength of the support beam.Don't know if people want to cut things on their car,but with this extra lip in there,there is almost no airflow going true there.So the coupe/ sedans have a little advantage.

Watching this with interest. Keep up the good work!

By the way, have you considered a duct like this?

Thanks Will do.
Yes i looked into that duct ,but since you have to cut a hole in the bumper i didn't want to do that.
That air duct would be much easier and more direct for airflow.
But it doesn't guide the air towards the filter or airbox and it still allows air that passes the radiator or ac condensor to get to the filter.
Which is hott air.

Agreed that the duct is not the only piece required and that it is not ideal to cut the bumper.

Hopefully there is enough clearance for your idea to work well.

After a lot of work with lots of errors i finally got to test the carbon air scoop and lower air duct today.
End result is under WOT the temperature drops immediatly 3-4°C .The heat soak now is max +7°C over ambient before without the scoop it would go up to +10 +12°C over ambient.Under light throttle and low speeds the heat soak is the same as before.
I also suspect the Radiator hose to still heat up the airbox ,so i might go and put some heat wrap around the hose.

More info on H.N Innovations .

A small update , after testing the carbon air duct for months ,i discovered the carbon is touching the hood .This is due too the hood flexing so much under high speed afaik.(Great work honda :rolleyes:)
So i need to change the mold and add more clearance .I haven't been doing any work for months ,but will be starting again shortly.
I also recently bought a 3d printer and been working on a MAF housing that i designed a few years ago allready.I finally got the ins and outs of the OEM maf housing which has more features then i initially noticed .The SI housing size worked great on my non Si (LTFT where around 0% up to +2% in the summer) I now have the stock unit back on and LTFT are -7% STFT even goes up to -9% :hmm:.

The stock MAF is off by ~5-7% throughout the range, leading to negative LTFT's and running rich during WOT, especially when tuned. If the SI MAF housing is indeed up to 5% larger in diameter (so ~ 7-8% in volume) it makes sense that the trims are about spot on and it might be an excellent idea to make one "light race" MAF housing for the EU model ... I'd be a huge fan anyway :)
Great work so far Nick!

Thanks , that could be spot on.
The stock MAF and the SI MAF housing is tapered not straight (with 3 different taper angles) and it actually is smaller on the filter side and tapers up to the hose side.
Stock (non si) size is 57mm and tapers up to 61.5mm.
Si size is 60.5mm and tapers up to 63mm.So yes the SI MAF housing is 6% larger.
In the beginning my Si airbox ran up to LTFT +3%.
After a few weeks it turned down to 0% and kept there during the whole summer.Which was perfect.
I now noticed again how bad the stock fuel trims are with the stock airbox,STFT goes up high sometimes even -11% .LTFT keeps around -7% .The MAF model i made is slightly larger then the SI size which would make it between street and a race model.(or light race )I haven't got the chance to test it on the car since i need a custom airbox for it.
But i can say this if you really want you can copy the oem Si MAF housing size and have it 3d printed in HP PA12 MJF which is smooth and can handle temps of up to 95°C .
My first prototype is printed like this and cost was 150euro.But mine had additional features on it ,so a more regular maf housing (like the prl) with a connection for a filter would be a cheaper.A company named ZiggZagg printed this for me and was the cheapest i could find.

Having this cnc milled out of aluminium cost more then double that.(for 1 piece )
It only gets a little cheaper after 10pieces.

Just started using fusion 360 a few months ago but it's coming along nicely.
Need to start testing the MAF housing and see what Fuel trims i'll be getting.:)
I hope it al works out.

I bought an air duct that required me to cut a hole into my bumper and ended up needing to trim the metal support beam to get it to fit, not too bad, just stressful haha

Been doing some testing ... ?
3D printer has been running great,getting close now.
I also stumbled upon a OEM big or "race" MAF housing which can be used on the 1.5T(non si) .(more on that later)

I also 3d draw the lower air duct from the beginning .Seems like a good option to make a mold and cast it out of plastic instead of fiberglass or carbon fiber as its not visable and only guides air.The top halve that i made out of carbon still needs to be remolded.

Also had time to finish the chrome delete on my car , had the chrome trim wrapped in black and replaced the door handles with oem white handle's imported from the USA.

So it seems like my first idea with the air scoop wasn't bad at all since Spoon is doing the same thing for the FK8 ... :cool:
Honda Civic 10th gen Hondanickx Civic FC1 hondata-sema-spoon-k20c1

"Under the hood, a prototype carbon Kevlar intake sends air to the airbox, and Spoon says a lower piece will accompany to better divert incoming air".

Seems like they will also do a bottom piece also ... :hmm:
It's easier to do this on a FK8 since it allready has cut outs in the plastic and a lower air duct.

Since i allready bought shore 60A pu rubber to make some custom sized rubber hose reducers I also made my own inserts for my type r RMM .Used the RMM as my mold,and added a 3d printed flange around the rubber .
I used filliting wax clay to seal off any edges that might leak.
Shore 60A is a little softer then the perrin inserts(which are shore 70A).
I made sure the flange isn't too thick which makes installing the RMM easier.
I noticed others where having trouble installing the RMM with whiteline or perrin inserts.
I used Smooth-On Pmc 746 PU rubber .

Since my warranty is expired I'm going to be doing my own oil changes again.
Made this 3d printed funnel with threads today to make it easier to pour in the new oil.
Under The oil cap there is a sort of mesh which prevents a normal funnel from sticking in properly.
So this makes it easier ,just screws in.
I'm also going to be cutting open some aftermarket oil filters to see if there still are great filters out there.Oem honda ones are not that great anymore.
