I'd like to replace the under bonnet heatshield in my car but not the wing sections as these are fine. As such I'd like to replace the old one with an OE looking part.

Does anybody know where I can pick one up from? Also, do they come ready made to stick on or can you only buy the material and the services of someone with a sowing machine? hehe

Andy

I've just done mine and it looks very good.

Bought the mat from Racetechdirect and it cost £52.43 delivered and I also bought 2 tubes of high temp silicone from Clever Trevor for £29.82 delivered.

I cut it to the same shape as the original and had the edges sewn as original.

Colin.

yikes that's more than I was expecting, I can get non-OE material for about £15/m locally, but what price originality...

Nice chassis BTW Colin! yes

Yeh Andy, it wasn't cheap and the silicone seemed a little expensive also but when it comes to my baby I like to spoil her.I thought that this combination would give me the best chance of it looking good/original and lasting.

There is no way you should need to spend £30 on silicone for this job.
I spent about half of that and still used high temp sealant, but if you read about silicone sealants most will withstand high temperatures anyway and if you think about the job the shield is actually doing why should the sealant/adhesive need to be high temperature at all?

The easy way to fit the new shield is to remove the bonnet, but I did mine without doing this because I was on my own and impatient as usual.
I covered the engine with blankets/duvets etc to give it a nice padded area, then smeared the adhesive to the half of the shield nearest the screen. Fitted it into place, rubbed it firmly with a cloth and then layed the bonnet shut onto the engine and left it for a day or so.
Then repeat the process for the front end of the shield. Just be aware you will need a lot of padding for the front end if you have a pre cat because of the space in the engine bay.
You might need to go around the edges afterwards to stick them - especially at the front because of the curvature at the edges of the bonnet there.
Those little spring loaded clamps are good for this job - protecting your paintwork before attaching them obviously.

Don't worry yourself over how I did it
