it seems this might be worth doing, where can you get the new valve from??
will it work on my engine, or is it for a newer version?
should work on most engines, ino of people who done it to diesels and felt the difference, even people with alfa romeo JTD's.
im still in dispute weather to pay 60 for the allard blank pipe or just go for the blanking plate which is alot cheaper.
it seems to make sense as the EGR exhaust gas recirculation ... it will just be putting used nasty warm air back into the engine (manufacturers put it there to keep emissions down) ... so blanking this must mean strictly unused new cool air .... which would mean better combustion ... hence better performance and economy
theres another thing which was more suited for the BLT engines which was a small blanking plate with a hole in it, think it went onto a gasket pipe or something and it did the same thing. most people with skoda fabia VRS were doing it.
