Okay so before everyone laughs i am currently in the early stages of attempting to make a Gruppe M style intake for my Accord euro CL9..
This came on the back of a few mods i have done to bring the car back to a healthy state from nearly 200xxxkms of hard work.
Pictures and more details to follow. Will update daily

So heres the exposed pod and space i have to work with.
The original airbox and resonator have been removed (there are other DIY's on this) and the plan is to make a nice big airbox to separate the filter from the heat of the engine bay whilst channelling some of that cool air.
wish me luck!

First port of call was to mock up some space guidelines with foam i had laying around, foam is a great way of making a basic set of shapes which are easy to alter! heres a very quick look at what it looked like!

Next i pushed some chicken wire (ideally i would have had a smaller hole size but this is a budget DIY!) into the rough shape i had made out of foam and went for a test refit..
its very malleable to was also easy to make work.
N.B- for all first timers, make sure you keep in mind when making casts that casting the inside make it smaller and the outside makes it larger... make sense? im going to cover the outside of the chicken wire as its smaller than the original foam mock up!
heres a lame photo of some wire...

So here is the rough "papier mache" mold that i'm going to be basing the real thing off, obviously its not trimmed or anything nor sitting flush but all this can be fixed with my advanced fiber glassing skills (read: i can' t fiberglass)..
the plan is to glass it and add seals to be purchased at a further date to seal it against the hood seal and intake pipe.

Okayyy i have fiberglassed the the final stucture!
Its just like paper mache just much more sticky and messy! anyone else doing this make sure you wear gloves and follow instructions carefully!
i used a $30 fiberglass kit "Diggers" brand which was perfect for this size job.
Used all the resin and only have a tiny bit of matting left. To this point the cost of the job has been $30 and i envisage spending probably $10 more on seals and miscellaneous things. will post pics tomorrow as i forgot to take photos of it!

I still wanna see the finished product. High doubt for gains if any. I think his going to loose some killerwasps for sound here.
Good effort thou. Thinking outside the box, cause your a jew.
u mad?

Finished product tkmorrow, would have done it today but has to replace my rotors which look good too.
I would agree with te loss of power but I already has a exposed pod so it can't get any worse than It was. Like the sound anyway

Here is a bad photo because its night but will seal it and finish it tomorrow and post pics.
I know there is going to be a lot of hate coming my way but on the way to work it legitimately felt stronger through the revs. not quite as loud as a completely exposed pod but definitely punchier.

put the seals in today :) contemplating what finish to put on it but as for the structure and function its pretty much done.
sounds definitely tighter than just the exposed pod and i feel like its a little more torquey.
