Had this on my car for about 6-9 months before deciding to just use blanking plate for a bit of turbo flutter. The small spring inside broke which Forge sent me a replacement along with the coloured tuning springs. I put the small spring back then decided not to bother with it altogether. £75.00 posted or can be collected from Bournemouth. Cheers Chris
No the blanking plate is being used as I decided to take it off completely. Did see the point in buying another blanking plate just to sell it with the BOV
