Spark plug NGK or BRISK

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 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.

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.

Apparently these are good for my race car but might not be good for street application.

I was running the junky ford plugs with little to no issues and switched to those NGKs and now I will actually foul a plug in warmup. This has never happened before and I would venture to say they are my least favorite plugs at this time. I have never had these issues until the NGKs.
