Noticed that one of the plastic intake tubes was broken, so I replaced them both. Fortunately, the intake pipes only costs 11 euro per piece, which is a steal!
I added gold plated tape, to fend of radiating heat and keep the incoming air as cool as possible. Took quite some time and effort, but I am happy with the end result and how it looks in the engine bay.
