Spark plug NGK or Denso

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.

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

FWIW.....an electrical engineer friend of mine with a custom turbo BMW z-3 with over 500hp/500ftlbs at the wheels, did the homework and said NGK is one bad A$$ plug......he said unless you get into the really specialty racing plugs NGK is where it's at.....i say for the same money go NGK as soon as i get 20,000 on my 03 the NGK's you mentioned are going in for sure...$2.50ea was what i was quoted near me seems cheap enough compared to the $17ea BMW plugs i sell at work

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