Cheap: 8 Rapidfire #5's

[Aurora40]

I have 8 AC Delco Rapidfire #5's that have under 2,000 miles on them. $10 plus shipping (I'd guess about $3). I believe these work in aluminum head L98s.

Not cheap enough? How about $10 shipped?

They are in fine shape, they just aren't a good plug for the LT5. I swapped them with some NGK iridiums in a colder plug to reduce some torque-peak knock I was getting.

The LT5 uses rapid fire#9 not #5 The rapid fire is a good plug if you install the right one.

Not according to ACDelco it doesn't. #5 is the one.
