I decided to try out NGK Ruthenium, and it runs just as good if not better. Ruthenium is much newer technology and is supposed to be able to ignite a larger range of AFR's leading to better throttle response compared to good old iridium.

Pros: better throttle response

Mileage: 210000 km

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
