Looking for the proper NGK spark plug number?

And I have a 1991 240sx with a S13 SR20DET Redtop in it and the AC lines are different on the SR compressor so i was wondering how to hook it up?

Can i bring the KA AC lines somewhere that can connect them to the SR20 ones so i can connect the AC compressor? I have the SR20 lines and there cut about one foot from the compressor

ngk BKR7E regular copper plugs  
ngk BKR7E-ix irridium plugs.

copper works fine just changes them pretty much when you do oil changes. its what i do.

no clue on the A/C, edmonton is useless for having it anyways. look, april 18 and 1-3 cm of snow. gah.
