This is a very coveted 2Ublar 421 Manifold, which as we all know is difficult to get from them quickly. It has just been cleaned and Zirtec coated in white. I will double check the bore size later and post up some photos.
This came off a S1 K Series Elise, it should fit a S2 K series, but please check with 2Ublar before you buy.
Collection preferred from OX17 or I can post at a cost.
