dont suppose anyone knows if they are produced as a patent part? tried fitting mine today as old one is fubar, but was supplied with the wrong one. looked up in all catalogues i have at work and the one i was given is the only p/no. listed for a 2.0 16v, but being a 182 (with cup packs) cant find one different for it! has anyone replaced theirs and if so where did you get it from? if it helps the one taken off of the car is smaller than the one listed for the 172, both in diameter and length. need to get a new one tomorrow morning as im meant to be getting the car re-mapped and matched inlets fitted, but my car aint moving lol!
