Spark plugs

[Sandeagle]

After reading a bunch of stuff on this site I can never find what I am looking for. I just ordered a D.U.I. From 4 wheel drive parts, a recommended D.U.I. And the 8MM wires. I remember reading somewhere that some plugs are terrible. What are recommended spark plugs. Good plugs!!  Buy once cry once. Already have the 2150 m/c.

When I did the big cap/coil swap I bought new autolite copper plugs and the car ran like crap,
I put back in the champion platuim plugs and it runs great, there like 5 bucks each but I recommend the champion platinum plugs

Thank you,I think your post was the one I was looking for.

I prefer standard copper NGK's myself.

Champion or Autolite work great for me, gapped .35

[macdude443]

I've run the Champion Copper in mine and the NGK Copper that Eaglefreek mentioned.  No problems.  Stock gap is .35, post-HEI gap is a suggested .45.

I've been changing spark plugs for 30 years and I prefer in this order Champion ,NGK OR Bosch ,Denso. I've never had autolite or ac delco last for very long.

My msd ignition runs autolites gapped at .45. Never a problem very good fire with them. My stroker turns the tires in 3rd sr4 manual with 2.73's on my sedan.

Thanks everyone, gonna order both champ.and NGK and will let you know which runs better. Copper seems to be the trick. I am running champions now.

Unless the plugs were dropped or something, the Autolites should be fine with the correct gap. (there were 2 completely different ranges for our AMC 6 cyls, depending on emission equipment and head design)

I still like the NGK 2288s the best (BKR6EK) which are double grounds and idle without a miss with my HEI and stock carb.

Copper conducts better, Platinum and Iridium last last longer.

I've always had good performance with Champion & I'm probably the only who uses a torque wrench to torque the tapered plug to 11 ft./ lbs. The only plug I never liked was AC.

I personally like the performance and longevity of NGK.
