Reviews of NGK parts For Business

The racing plugs from NGK are exceptionally expensive, their standard Iridium plug is great as well. I wouldn't spend the money on the racing plug... I've tracked my car with the standard Iridium plug extensively and had no issues with plug wear etc. I personally feel that the racing plug is just taking more money out of your pocket for no gain/return.

I currently have them installed and gapped at .025. I don't know if they're making a difference or not but the car is running great so I haven't bothered switching back to stock.

I just switched out a set of Bosch's for the NGK PFR7S8EG's...and to me it's night and day.

I ran those plugs with zero issues for many years on my stage 2+ car gapped at .028.

PFR6Q was equivalent to the stock Bosch plugs. They work fine.

I used NGK BKR5E-7938 they are awesome plugs, i only paid $14 for mine but i have a friend who pays cost. they are around $80.

I used to run NGK tr55's in my mach1 but for some odd reason they had a tendency to become loose I thought it was my heads but I switched to a brisk plug over 30k ago and haven't looked back I will be buying them for all my cars.

installed new plugs and R8 coils today no misfires anymore. this car is f'ing FAST now!

yeah ive ran them.... i guess there ok but they foul faster then the iridiums...

I went with some NGK coppers. I dont know the exact part numbers of them but the ones I got were crap lol My MPG went down to 19 mpg.
