Make sure to select correct size for your application Made of .250" 304 stainless, very similar to factory piping size. Great for blocking EGR to test for air leaks/coolant leaks. Plates with gaskets and copper nuts are meant for turbo manifold applications whereas plates with gaskets and bolts are for egr valve/cooler applications. Large: CJAA High pressure EGR at turbo and EGR valve at the intake CKRA High pressure EGR valve at the intake BRM at EGR cooler and EGR valve at intake BEW/BHW all ALH all V10 TDI all except exhaust manifold Medium: CJAA at low pressure EGR valve/cooler BRM at turbo Small: CKRA at low pressure EGR valve/cooler CKRA High pressure EGR at head
