I just replaced my original injectors on my 1977 300D with Bosch rebuilts I boughtfrom FastLane.

Popped the old one's out and the new one's in. I was shocked at the positive performance difference. Easier start-up, smoother idle, less valve clatter, holds speed better going up steep hills, and I gained about 10 mph in top speed.

Best $ I have ever spent, maybe I was just lucky.
