Description Reviews Craven Speed Hotlink Adapter The Hotlink does not sit in line with a factory sender like the other adapters, but it does install easily without permanent modification. This piece replaces a coupling in the coolant hose of the second generation MINI engine. Our Hotlink coupling has a 1/8 NPT threaded tap for the sender. Thanks to your feedback; this adapter will now work on all second generation MINI models with or without standard transmissions. Instruction Hot Link
