Subject:spark plug upgrades.....3 electrode for 1.9L and 4 electrode for 2.1L
From:Smola, Tony

I upgraded my 1.9L to the Bosch 3 copper electrode in my 85' years
ago......forgot the part number.....will post it later....but it works
fine....same price as stock.

The 2.1L has the option of installing the platinum + 4 plugs.....a little
more money, but problably lasts longer than stock.......

Anyone know of the Bosch number for the 3 electrode sparkplug that fits the
1.9L?........brownie points?

Springtime tuneups are soon upon us and I think tuneup advice would be a
good posting......
