Why?
i find the sausage ones have alot more surface area for veg to go through easy, those chrome ones the filter part is very tiny, plus those sausage ones have been on many cars now with out a problem so far, and you can buy 5x for just over a tenner i think on e-blag/
i did buy to try them but as the others worked well didnt tchange to these. so just stuck in the shed...
