Spark plug NGK or OEM FORD

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've noticed something interesting about the NGK BKR6E's that I'm running. #1 - They respond extremely well to the chip and the N75 J valve. #2 - I've also lowered my gap from .032\" (stock spec) to .028\" to reduce the possibility of misfires under high boost. The bottom line is that the BKR6E at .028\" is a great plug for the 1.8T AEB motor.

Im using BKR7E and I can say for $10 it made my car run so much better.

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.
