Spark plug NGK or Autolite

Spark Plug Gap - Measuring and Adjusting NGK - BKR5EKUP

My personal preference is NGK's, I run em in everything I've ever owned. They seem more reliable, and last longer.

my 570+whp civic buddy terry couldnt get past 574whp... the plugs he was running, bkr7e race plug, had alittle brown speckle and melted the number 3 plug. after letting the car cool down for 30 mins or so, instead of retarding timing to run more boost he slaped in a set of ngk r5672a-9 plugs... and upped the boost 2psi from 27psi to 29psi... and BAM!!!!! 616whp.

Same plugs I'm currently running - used them with my Jacobs ignition, and they work like a champ.....

NGK v-power's. they are the entry level plug but they work awesome. there's no real need to get super pimp plugs though, i mean, it's not like they are going to add 10hp or anything

I have had no problems using the NGK BKR5EKU plugs. I do not spend the extra money for the platinum version. The copper plugs are fine.

Last time I tried the 3922s and I was pleasently surprised with how smooth the car runs. I haven't had a misfire code since I changed over.

On a stock or chipped VR, the NGK platinum OEM plugs (BKR5EKUP) are pretty good. I have tried the Bosch F6DTC (16V copper plugs) and NGK R5671A-7 (copper) for about 10K and 6K miles respectively on my supercharged VR and both seem equally good.

I know LOTS of people running NGK BKR7E's who are chipped w/o problems.

don't feel like changing them every oil change like I did with the autolites that constantly misfired...
