In terms of the intakeside, even if the BLUE SKY SHEET came off, it would stop at the airfilter, so it must be fitted to the intake side for safety and efficiency. Q6 Can anyone fit the BLUE SKY SHEET easily? A6 You must look at the airfilter box carefully to assess which is the intakeside or engine side. If the fitteris not competent, there is the possibility of fitting the B.S.S into the engine side.
