I tried Bosch plugs on a 1995 NG900. Problem as described. When they state compatible, that might only address mechanical fit. Stick with the original plugs

Cons: problem as described

Vehicle: Saab

My brand new out-the-box WEN 3500 would barely start until I tossed the Torch and replaced it with an NGK. It now runs as designed. Too many others have had similar issues and that's why Torch is widely regarded as junk.

Pros: runs as designed

Cons: barely start
