Spark plug NGK or BRISK

Just thought I'd come back and post what I found to possibly help others. New coil packs solved the issue. All of them were in pretty rough shape when I took them out. Picked up new packs from the stealer for $60 a piece. Also bought the NGK BKR7E's, Gapped to .28 best I could. Fuel economy has returned thankfully, and low end performance is great. The turbo seems to be building boost a little more easier, and it takes less throttle to get the car accelerating. Can floor it from 2500 rpm to the limiter at 6900 without any hesitation, hiccups or blips in power.

I'm running NGK 1675 PFR7S8EG plugs with OE R8 red top coils with APR Stage 2+ with no miss fires.

When I upgraded to R8 coil packs I swapped plugs to NGK Platinums and did nothing but thread em in and walk away. Nothing but great performance since.

Finished up another swap over the weekend. Runs great. Gapped a new set of BKR5E's to .032" and put them in a buddy's daily driven B4 VR6.

I actually have those exact plugs in mine for about 10K miles now and have not hat any problems.

I have been using them, never had problems. Start up is faster, idle is smoother, throttle feels more responsive.

I miss my NGK V powers. I always ran them in my 1.8T's and changed them every oil change because they were so cheap to buy. Put these in and she's as smooth as butter. Torque profile feels better at partial throttle too. Needless to say I am very happy.

I began reading and ended up buying a set of NGK BKR7E-11 (Stock# 4464). From researching, it looks that the ones I got had the v-groove center and a little less projected tip. They are also 2 steps colder. It's been about 3k miles and the car is running great. Big difference over the Denso plugs as far as smoothness. I did not notice a difference in mileage.

I've been pulling my CR8EIX iridium plugs out to check how they are burning a lot recently. I've been seeing some light ash deposits and high speed glazing and the iridium tips of the plugs are not as hot as I would expect them to be, i.e., they are not *white*.

I changed them over to the NGK bkr7eix #2667 and was wondering if spark plugs would have any effect on boost? It seems like the car isn't boosting as it should, I have a boost gauge and it also seems the PSI is a couple LBs lower than before the spark plug change. I have not experienced any misfires (that I can tell) and no CEL it's just the boost doesn't seem as high.
