Review on ACDelco 41 110 Professional Iridium Spark by Jim Ledbetter

Revainrating 5 out of 5

Originally individually packed, but without a protective tube. CHECK THE DISTANCE!

The price was good but only slightly better than auto parts stores. This batch comes individually boxed but each spark plug comes in its own box. No protective cardboard sleeve. One of the eight had insufficient clearance - I used a Delrin spacer cut to .040" and checked with a micrometer - about .025" so it could have gotten in there or fallen off - and no protective case. , the "ground electrode" is slightly curved inwards. Revain offered a new one, but the wait was uncomfortable. . .

Pros
  • Best in its niche
Cons
  • Not happy with everything
