Need new plugs & wires
#11
Chip, this topic is about plugs and wires. Please try to stay on topic. The brake information will rapidly take this off-topic.
In addition. Bosch themselves have acknowledged that their spark plugs (of all designs) are a poor choice for waste-spark ignition systems like ours. Knowing this, it'* very poor practice to suggest them to any person owning a car that uses this type of ignition system.
Bosch acknowledges a problem with using their Bosch Platinum spark plugs
in engines with ignition systems that employ 1 coil for each pair of spark
plugs (also known as a "waste spark ignition system").
The problem that Bosch has acknowledged when using their Platinum plugs
in engines with waste spark ignition systems stems from the tendency of
electrode metal to get transferred depending upon the polarity (direction
of current flow) of the spark. In waste spark ignition systems, 1/2 of the
plugs always see reverse polarity sparks. Given the very narrow platinum
center electrode of the Bosch Platinums, performance will be degraded more
significantly when reverse polarity sparks will cause material to be
transferred from the large ground/outer electrode onto the narrow platinum
center electrode'* exposed end surface.
All GM 3800'* are Waste Spark. This is not a myth. This is from Bosch themselves, and the information was obtained the same way I obtained my information above from NGK. A phone call.

And it'* not just them or us:

AT LEAST a 36.25% failure rate in our sample size of 80 vehicles
17.5% failed immediately
Another 18.75% that didn't fail immediately failed within 20K miles (premature for a platinum plug)
There are still another 31.25% that are working so far, but haven't accumulated 20K miles yet. So they are "up for grabs" statistically, an could inflate that 36.25% failure rate even higher.
Still want to gamble?

And there'* more information out there.

OK, but the ones at Advance auto parts are: (Iridium IX Plug; TR55IX) & since there is no NAPA here, the Beldem wires are not available for me. Should I stick to stock ones or is there a better option. We have PepBoys, Advance, & Wester Auto.

I'm fairly certain Pepboys doesn't stock any 8mm wires, even their best is only 7mm but they have a lifetime warranty and I've replaced them 3 times so far.
And Wetern auto is part of the Advance Auto/Parts America franchise as far as I know so I doubt they'd have much different.
I can't comment on the irridium plugs, I cant remember if they were a NO for our engines or for my truck...LOL
