Spider - 105 & 115 Series (1966-1994)
Hi,
I recently bought a 1982 S2 Spider, and since the engine was failing, I checked the spark plugs (NGK B7ES), and they were severely worn out.
From what I read on several posts, I ordered 4 Bosch Super 4 WR78X, and to my surprise, after replacing the worn out ones, my car won't even start...
