- Bosch Makes a Silver plug and it is the ONLY type I use in my Merkur XR4Ti
- In my case this has been the only plug that can withstand the boost this
- car produces...I do have some modest mods to the engine, but nothing
- outragous,,,,
- The Plugs are expensive.I pay 6-7 bucks a piece but nothing I've tried
- works as well under sustained boost as these plugs...
