I find that they are an acceptable middle of the pack plug but most people like the tr55. Any reason you didn't go with those in the first place? They aren't expensive. Have had some bosch go out on me before

Stay away from Bosh plugs, do yourself a favor and get some Irridium plugs (they are OEM now).
You won't likely ever have to replace them again.

I run the Bosch 4505s in my LS6 with no issues.

I have run Bosch plugs in a variety of applications for many years, including cross-country motorcycle racing which is particulary hard on spark plugs, and I have had consistently good luck with them.

I have Bosch and have no problems, when i change my heads I'm thinking of going with the Champion Iridium.
