i see a high range in price what is the reason for this in a spark plug (side question thanks)

Read their FAQ. It explains a lot about sparks plugs: copper vs iridium vs platinum, gap, heat range, etc..

thanks for the information

what do ppl think about iridium pulse plugs, good investment? not worth it?

i was looking at how they work seems interesting the

Pulstar Iridium Pulse Plug BE-1i BE-1 (for my 2004 530i)

Also can i use this on a non modified engine, my car is stock ( was reading stuff about heat ranges)

also what should my GAP be? Id like to buy a set of plugs with the correct gap

Personally I just stick to copper plugs. I honestly forgot what the OE gap is. You can't really gap iridium or plat plugs.

I thought the plugs are pre-gap if you buy it directly from BMW part store.
