    super ETA spark plugs

    What are the proper spark plugs for an '88 325?


    All the documentation I can find reccomends a different plug for an m20b25 compared to an m20b27, but since the 88 "super-eta" has an 885 head I'm a bit confused which type of plugs to use? I'm guessing anything that works in a 325i will work in the super-eta?


    Thanks guys.

    It should be W8LCR which is now WR8LC or something like that. WR8LC+ has an yttrium conductor for longer life. 325e WR9LS has a silver conductor and are very expensive.

      Thanks, new plugs in place :)

      Old ones had oil on them though :(

      I hope its leaky valve stem seals and not bad piston rings. I need a compression tester.
