After 16k miles, the crappy jubilee clips I'd used on my charger to intercooler pipe finally gave up. I'd intended to change them a long time ago, but never got round to it - in all fairness, they did quite well!

Normal service resumed again, thankfully! This car really is pointless without forced induction!
