After 2 time replacement ( 5 hours work ) of the original manifold , 1 used one, next with new flex hoses wig welded by a pro welder, both broke in short time again.Installed K-TEC manifold 2 years ago. Main concern was pass of German technical inspection every 2 years(TÜV) including exhaust test.Clio passed test 😁 ( And yes I know, officially is not TÜV conform).Best improvement, to get rid of the main CLIO 3 RS problem.
Great car for turning capabilities, nice upgrades to the engine too, although am ep3 ctr with the same upgrades hits at least 250. Not so good brakes and turning capabilities though!
