I've noticed that I'm starting to get rfi when I'm listening to the radio, I guess that means my suppressor's on the way out? Whereabouts on the car is it and where can I find a replacement (I've looked on MX5 parts but couldn't find anything).
When I bought the car the previous owner had butchered the ISO connector so I had to do a bit of TLC on the radio harness. I'll have the HU out and recheck the connections, especially the earth,
