Spark Plugs

[TomFraser]

I've been looking at all the types of spark plugs, and looking at all the different opinions of people on which type to buy.

Are there great differences between the $2 and the $8 spark plugs?

Whats the difference between normal, platinum, iridium, and is it a big difference?

I've looked around the internets but can't a good opinion that is backed up by any facts, just people saying that "my engine runs so much better with (x) spark plugs"

Thanks for the replies

i run copper ngk v power in my 2j, heat range 7. they are cheap ($1.80 each). i replace my plugs once a month and gap to .28

use to run ngk iridium till someone local to me blew their motor cuz the tip melted and fell into the chamber and blew a hole through his piston.

whats the logic behind replacing them once a month?
