Spark plug Bosch or NGK

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.

VAG engines seem to like their factory recommended Bosch plugs better than any other.

I used Bosch W4CS (cheap plug) with good results in my G60.

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

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.

I just replaced my plugs in an 89 16v yesterday. I ended up getting the Bosch platinum +2. I was leery of the platinums as everybody seems to knock them, but my car runs fine. They were 4 bucks each.

got my f6dtc's at the dealer (only place i could find them), and they were around 4 bucks a piece. car ran like a dream.

You do know that a bosch "7" is 1 range HOTTER than stock and 2 ranges HOTTER than a NGK"7"

I have a strong opinion in not suggesting the Bosch or the Beru. There is a reason that BOSH is no longer the OE spark plug in VW, Audi, BMW, Mercedes Benz etc., etc... Stick to the NGK, especially in a VR6, NGK has been OE since the intro of the VR6 six months after Bosh failed to produce a plug that would run in these engine during start up. The Bosch had nothing but running problems.
