The new intake is now fitted. The installation is quite tidy, with the Green Filters air box sitting underneath the battery tray. I have one bracket left to fabricate to support the MAF sensor properly. There is a bend in the pipework fairly close to the MAF, which is not ideal, but the diameter change from inlet to outlet on these MAF sensors seems to make them less susceptible to non-laminar flow effects.
Performance seems to be much as before but the annoying level of induction roar has gone.
