Reviews of NGK spark plug

the BKr7e's NEED to be switched out with every oil change (IMO).. The new plugs feel great and look great on vag logs (less timing pull than seasoned plugs)

I went to the dyno today and ended up with some pretty good #'s 321HP 304TQ Car was ran on SPS3 settings boost 9 timing 9 with Sunoco gt100 fuel. Temperature was mid 70's My car: 2003 A4 1.8t quattro ATP/Revo GTRS ATP Manifold Ecode Front Mount Intercooler Ecode Test Pipe Neuspeed Xtreme Turbo intake pipe Neuspeed Exhaust Stock airbox with K&N panel filter stock N75 valve working And NGK BKR7E plugs South Bend OFE SS clutch I could have done better if I had the right plugs (Bosch 3 electrode) and a manual boost controller but im pretty happy overall. Also the car was pulling 0 correction factors all the way through the rpm range so Lemmiwinks could have helped me with some more timing.

BP7ES gapped at .025 aren't doing it.

Cooler plugs (NGK BP7ES) gapped first to .028, then to .025 have changed NOTHING.

I put in a set of BP6ES today, gapped to .022", and had every bit the misfiring problems as before, and probably a bit more severe and more frequent.

I run ngk bkr7e plugs gapped to .024 at 15psi. No probs here.

Mine popped up with the NGK's all i did is tighten the spark plug a little more and it stopped.

I have been runing the NGK BKR7E which is one step colder than stock (NGK Part# 6097) and I have a K04 with GIAC K04 software and other mods. They work great with a .028 gap. I change my plugs every 5K.

I just installed some of these NGK (BKR6E) plugs. I set the gap to .030 These went my 99 A4 1.8T Avant Quattro. The car is stock except for a K&N filter. Idle seems awesome and flawless all the way through the rev range.

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