Re: GSR Air-Flow Induction Hose
When he first started these kits they were made by SFS, superb firm, good pedigree etc, but expensive, so he switched to someone else before getting his own tooling. Now GSR have their own tooling they can knock the kits out using cheap silicone.
Its exactly the same with the filters, they raved about how amazing BMC were, CDAs, twin cones etc, but they are expensive for a reason, quality. So they switched to some cheap Chinese filters, cheap, but they tell everyone they have better flow rates than BMC.
After the dispointments i've had on a personal level with GSR and seeing this episode I wouldn't recommend them at all.
