spark plug choices

[fisher83]

So I know that spark plugs dont "make"more power, but I do have a heavily modified motor and was wondering if I should run the stock copper plugs or would I benefit any from something lime platinum or iridium as far as longevity goes.

Copper is best, just depends on how cold you want to go, BPR7ES or BPR6ES. Keep it with NGK, time tested and proven, especially in our community.

I'm not sure those apply to the non turbo 420a motors.

The 420A cars came with NGK BKR series plugs.

I was meaning the BPR series. I wasn't throwing NGK out.

Didn't relize this was in the 420a subforum. Disregard my spark plug choices, I don't know the first thing about the 420a, read: zero.

I know, I was just clarifying -- I should've quoted IrishBeatdown's post instead.
