I've got the EGR ones on the Disco, mainly cos they were cheaper than the Climair ones at Billing.
The y have put up with the abuse of three Belgium Nationals and a few other trips and, although scratched, are still in position and not cracked. :D
I had the Climair ones on my 90 and they were just as good TBH, although I did manage to crack the edge of one when I put it on, not a problem with the EGR's.
