I`ve had a allard intercooler fitted to my E46 320d, however the original boost pipes do not fit the intercooler inlet/ outlet ports due to the original pipes being too small a bore and sfs performance do not supply a direct fit silicone boost pipe set. They would have to make a set of silicone boost pipes, but due to the length required they would have to be a custom build. They have expressed concern that due to this length, it may cause swelling of the pipe and possibly burst due to the boost pressure.
Basically the bore of the original pipe is too small to fit over the bore of the new intercooler.
Is there a hard boost pipe supplier that I can get in contact with that will supply pipes?
