Review: Fits ok but be gentle - Fits absolutely fine on 1.9 cdti 120 engine. Be gentle with the pipe when pushing it on, bit by bit. Little bit of plastic burring might want trimming but its nothing to worry about. I thought at first it didn't fit, the O rings are slightly larger than original. Remove the E clip first, remove old connector. When inserting new one use something to push the top down, i used pliers and leaned my weight on them and you can feel it drop in. Replace e clip. Then carefully connect pipes and good to go. Im first to moan about stuff that doesn't fit but nothing wrong with these at all.
Review: Poor Quality. Broken on arrival and others on installation - Unfortunately one of the set was broken on arrival. Not a problem as only need 2 from the set. However, these snapped on installation also. Very brittle plastic. I will now go to a main dealer and buy OE for improved quality.
