Question: Anyone Using AC Delco RapidFire Spark Plugs in their C3?

[L82Dan]

I was wondering if anyone has or is using the AC Delco RapidFire #2 spark plugs in their C3's. If so, how do you like them or don't like them? Any problems with performance, drivability, or poor mileage, etc? I want to change my plugs and was debating about using these vs the standard R45TS.

Thanks for your feedback!

Just had my 72 out for a drive last weekend. After setting unfortunately for most of the summer.
I have about 3 years on the R44TS standard plugs and it runs great. Can speak for the Rapidfires but if what's in it works.....

Thanks,

Mike
