well I searched and found this part number for a SR20DET spark plug: BKR7ES-11  
and I found this number, I think for a CA18DET? BCPR6EIX-11

but I went to crappy tire and bumper to bumper and crappy tire couldn’t even get in the BKR7’s and bumper to bumper can only cross over a copper and an iridium($16 each!!) and I was hoping for some platinums.

any help? do I have the wrong number, or is there just no platinum that will cross over?

thanks

Copper are just fine, just change them more often. Platinum and iridium etc just has a longer life.

well it seem like the platinum and iridium have really fine electrode tips which help ignite the air/fuel mixture by creating a smaller but hotter spark. and that is more what I am after than what the tip of the electrode is coated in.  
I agree, as far as basic operation copper is great, it conducts really well, just wears out slightly sooner. and iridium seems too expensive for what it accually offers. so the platinum is a nice compromise between the two at a more resonable price.
