i have 02 mini cooper s with some mods recently add, it has msd ignition coil, bigger intercooler, i put the alta performance kit with 17% pulley, and yesterday put the pulstar plasma core spark plugs (be1h10) and went to a ride and when i push the pedal began to fail, so i put the ngk spark plugs and fixed but already spend $60.00 with the pulstar, does anyone know if they work or not?

 

Pure snake oil. Stick with NGK.

 

The metal crush washer on anything but NGK are made of inferior composite metals thus even after torque to spec, they eventually blow out stripping the threads = you saved nothing.....Stick with NGK.

And never use anti-seize compound on the threads !

 

Ok thanks for your replies, just the last question what ngk plug do you guys recommended for the 17% pulley? Iv been searching and this 2 models came up :

NGK BKR7EQUP (4285)

ngk BKR6EQUP (3199)

could you recomend wich is correct?

 

I’ve never used anything but NGK plugs in any of my cars, when I did I ran into issues. My previous car was a ‘96 V6 accord and I never had a problem with the NGK plugs even though it burned a little oil. Car before that was a ‘92 Accord and ran NGKs in that too. Switched to them in the R50 as well.
