Which power stering fluid ok?
 

I've got a 94 E420. Since my car didn’t come with a manual I cant check it there. What power steering fluid am I allowed to use? Does my model year require the use the MB fluid? Fastlane has febi Bilstein power steering fluid. I am assuming that that’s okay to use. What about ATF?

While I have your attention... any recommendations on sparkplugs (brand and model/type) ????

Any power steering fluid except ATF. MB, Febi, auto parts store, etc. What FastLane sells is good stuff.

These cars have resistance in the wires or plug boots so you don't want resistance plugs. Stick to the proper Bosch Super plugs and you'll do fine. Some folks have problems with platinum plugs of any kind, even Bosch. Again, FastLane won't steer you wrong.

Spark plugs: Bosch F 9 DCO (original equipment)

Anything fancier is just a waste of money and will probably give you worse performance.

thanks for quick response guys. So bascally any quality power steering fluid is fine...cool. And thanks for the spark plug info too.
