Bosch, keep the ngk's for Asian cars and autolite's for fords.

put a autolight plug in some newer asian cars and it will instantly have a misfire. i just prefer to run what came from the factory.

[MR 325]

I run the OEM spec Bosch Super in any N/A M20.

[redsubdivisions]

OEM Bosch's for me. W8LCR's. Single electrode. None of this 4-prong "gives you more power" bullshit for $3 more per plug.

[nando]

I use NGK BPR6ES. single copper electrode. excellent quality. Bosch coppers work OK too if your motor is all stock.

funny, BMW seems to think NGK works good enough to be the factory plug for the S54. But I guess you're smarter than their engineers..
