AC Delco, I've heard other folks have had poor luck with Bosch as well as others.

Denso and NTK have always worked well for me. They're OEM for a lot of manufacturers as well, though perhaps not for our trucks.

I've used Bosch without issue, that's what NAPA and O'Reilly sell. Just got the front left one done couple days ago. I woulda done it myself but couldn't get enough leverage from the right direction to break it loose. Mechanic puts it on the lift and is done, r&r in 15 minutes.

biggest problem with the bosch is rednecks going to autozone and getting the cheapest one available, the one that requires splicing in (even includes the butt splices). i used bosch on my dyno for the wideband sniffer, and rarely had to replace. throwing it on the floor, contaminating, knocking against the internal pipe wall, etc

appreciate the replies I had read a couple of bad reviews on the bosch but no real reason I had one replaced a couple of months ago it needs replacing again not sure of make a friend with a shop put it in due to drowning it with anti freeze changing a head.now I think the flooding issue from miss fire and no start may have contaminated it again with fuel this time.he ordered it from his jobber so may not know brand then again it may not matter as I said fuel contamination may be reason.will see if more input more on their choice.
