Today, after about 3 months I let my 172 breathe better, I fitted the BMC CDA and Samco hose bought from Dave, its very nice, now I have a nice deep sound as well, it was a pain to get a cold air fed from the grill but I managed as well, and as advised bu Andy_GDI, i did not connect the cold feed to the airbox,just left it by the inlet on the airbox. I am very happy with it, but small problem, to work better i took the battery out and I cant find the code for the stereo, if any one can help me on that i would very much appreciate it, thanks. Vince. PS Shouls upload pics tomorrow of the airbox as well.
