Spark Plugs For 733i (1983)?

[Rudybs2003]

I purchased my teenage daughter this car and with a little work it runs great. My loacal Import parts dealer said htis car needs the Bosch Silver spark plugs (wich are a bit expensive; about $9.00each). Is there another type of plug that can be used and give the same performance?

Also I am not able to reset the OBC (On Board Computer) , it keeps polling. Is there a way to test it to dertemine if it is good or how can I reset it ? The last 7 digits of the VIN are 7853203.
Thanks for your advice in advance

The BMW parts catalog calls for Bosch WR9LS spark plugs. Also, if you go to the Bosch website they probably have 2-3 options for your car, though it's a little hard to navigate as I recollect. Here's the link to the Bosch website:

For the OBC problem, try to disconnect the battery for a few minutes so that it'll reset when you hook it back up. If your car has a radio code you'll need to know it in order to get the radio going again.

The only plugs you should use are Bosch WR9LS.If you do a little shoping around you can find them for aprox. $6.00. They last for aprox.
25,000 miles . Any other plugs will cause a rough idle and stalling.
You shold also NOT use any anti-seize compond as this will cause a heat transfer problem.
