Coupe B2 Service Parts

[IronJaw]

Hi, I'm after buying a load of service parts to bring our B2 coupe back to good health. I've just perused Euro car parts and some of the stuff they offer I'm not sure of. As a general rule I like to stick to known brands for things like spark plugs, coils etc. So Bosch, Champion, Lucas. I'm after some advice from owners of what and where is best to buy from. Below is a list of items we need, so any input is appreciated.

1) 5 x Spark Plugs ( I've found Bosch to be best)
2) Set of HT Leads
3) Distributor Cap
4) Rotor Arm
5) Ignition Coil
6) Air Filter
7) Oil Filter
8) Belts

Another item I'm in desperate need of is a thermostat housing. If anyone knows where I can source a new or good replacement I'd love to hear it.

Thanks In Advance
S.
