[perryyip73]

For those E46 325 owners, what is the spark plug that require to install in ur car. Currently i tried DENSO IRIDIUM POWER IK27 0.4mm. It can be install, but no idea the gap is good for my 325ci SMG.

Not sure / no idea about DENSO IRIDIUM POWER IK27

As far as I know, beemer mainly use the IK20 range. IK20 has gap of 1.1 while your IK27 has gap of 0.8. My advise is change it before it ruin your engine.

P/S - that 0.4 advertised by Denso is the DIAMETER of the electrodes. The gap for IK27 is 0.8.

i think you can also use the NGK BKR6E instead of NGK BKR6EQUP... for Iridium can use NGK BKR6EIX
