Owner reviews for spark plug

Now I'm running autolites one range colder than stock at .028 and they run great...

using the BKR7E for the past 6 months without problems.

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 once had to use 99 cent Champion plugs in my car for a few months when I was flat broke. They worked fine but didn't last long.

I was running the bkr7e, but I fouled two of them in 1000 miles

Just installed my autolites 3922 (one range colder than stock 3923) they were gapped to 0.025" with this gap I'm having some problems on hot startups, colds ones are ok. I'll regap them tomorrow and see if it gets better, maybe I'm having some loss in performace as well due the small gap....
