What is the proper color for an intake manifold?
Also is powder coating the only option that will last?

I did two or three sets of intakes and valve covers, powdercoat, the shop had alot of samples and they mostly used artic silver color. It turns out excellent, looks completely normal

If you go PC, Prismatic Powders has a specialty powder called 'Feathered Bronze' that's very close to original. Get a color swatch ordered first if you go this route as they don't always mix it up right! Tell your prefered Powdercoater to order up a few pounds for your job.
Note: this intake has a 60% gloss clearcoat on top.
Paint should be an easier match if you bring a color sample to your local auto paint supplier.

Hi all any one know the colour code for the beige inlet and camcovers row SE cheers

Hilton

Yes, Zermatt silver, just like regular S4 and GT. It was not beige when it left the factory, it goes that beige colour with age, heat and poor choice of cleaners.

I find that hard to believe . To uniformed colour and same on three cars that i own and seen the same on many other cars ?. Any one else got clues cheers.

Hilton

Its not a question of belief. Look at the photos in a factory brochure of the S4 engine e.g. 87 S4 brochure, or 90 S4/GT brochure, or 91 S4/GT brochure all have full-page shots of the engine out of the car (from a couple of different angles).

Of course, I have also seen a few photos of people's cars who thought the beige was the factory colour and had it matched when refinishing their engine bay

I worked for the printing company that printed many of the Porsche brochures and magazine inserts.
Those were the days when we had a difficult time getting silver and grey's to look correct. Grey computer boxes were really difficult. Times have changed but then we focused more on interiors and exteriors. Everything was a compromise

Dave928S

Mechanics who've worked on 928's from new confirm the silver is stock, and if you look at brochures as Hilton mentioned, and also look at factory videos you'll see they're silver.

They turn beige over time with heat cycles and engine bay fumes ... look at old white paint in many other applications, and you'll see what age, heat, pollutants, etc, does to painted surfaces in extreme environments (which an engine bay definitely is).
