I was happy to find it, so I thought I`d mention it here that our d24/d24t (=vw diesel) injector heat shields in this picture can be ordered from FCPEuro at $2 a piece,
they are thick black aftermarket ones and they do stick to magnets, ... but the set that came out of one of my spare engines, those wouldn`t stick to any magnet.
(They were in bad shape and I tried to refurb them using some techniques suggested here on the forum (!strictly for fun!) but all of them developed cracks immediately.
Originally Bosch shields are also metal (black), I had a chance once to buy them in their old school original bags. (30pcs/bag i think). They seem to be much thicker/stiffer than the `copper` (?) ones.
A picture can only* show the ones that do stick to the magnet.
. Ps. Yes, there`s 1 `metal` type shield in that bag (They are used, won`t go back on any engine, I kept them for reference only. 2nd pict shows both sides of unused ones, also the fcp part number (ignore my handwriting on the bag).
Keep bricking guys.
