FINALLY
 

well u guys finally convinced me....when i was at checker today returning the CCS, i said to myself, why not get something....hmm...and so i bought 6 TR55s! Aren't you proud of me?!?!?! lol i am slowly anti Bosching...my o2 is still Bosch, but that is not due for like a year, so i will buy a delco in a year and do it up then...THEN, my car will be 100% Bosch free (unless GM has some other bosch stuff in there)

oh yeah, i will be installing them this saturday..PEACE!

As far as Bosch goes the worst thing would be a Bosch O2 from experiences of a lot of members. I don't think plugs are necessarily bad being Bosch as far as I know, but the TR55s are a good choice!

Bosch plugs are equally as bad as the O2.

I'd be surprised if your O2 lasts the year you want it to.
In fact, I'd bet it's already costing you. And I'm one of the victims.

I remember using Bosch plugs before I switched to AC Delco Rapidfires. I don't think I had them in long enough to notice any ill effects.

My Bosch O2 went out in 2 weeks. I was pissed. Check engine light came on, and the same P1133 "O2 Slow Switching Rate" code came up again. WTF? Got a Delphi O2 in there, and everything has been fine.

I used to think Bosch made nice stuff, but never again.

Your FPR is bosch..should be..right?
I am a Bosch victim too, back yonder a few years ago, i tossed a plug set in my FIRST SSEi...yeah..3 months and they were toasted oats!

yeah i know about the bad o2, i put it in on August 16th of last year...and its still ok...so we will see....

i would replace it right now....but i dont have that kinda money floating around!!! i had enough to pay for the plugs, and as for the 80 from the CCS, i have to keep that available so that i can get more stuff for the CC to diagnose it!...

i will let yah guys know....

also, what is the recommended plug change interval?

oh and, i know my o2 is ok for now, my engine puts out a PERFECT air/fuel mix through all RPM ranges....

well if Pat (93SLE) is right its ever 13 years or so :roll:

but id figure a yearly thing, anybody say otherwise?
