Hi Minione Sam,
the Vipers are a nice
mod. as you now know, but I found the cold air feed pipe was just a bit fragile and after a couple of weeks it fell apart on me (reinforcing spring came apart).
I found a really good replacement on Demon Tweeks Motorsport site, they do a double skinned reinforced pipe, in red, very fexible and good for temperatures upto 300C (used for brake ducts).
