Spark plug NGK or OEM Subaru

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 can only comment on the ZFR5E-11 ... and let me say...THEY ARE AWESOME. Now of course these are not "official" OEM spark plugs for our engine, so just remember that...but the results speak for themselves. I'll say it again for effect... THE NGK ZFR5E-11 STANDARD COPPER SPARK PLUGS RUN GREAT IN VW 2.5L INLINE-5 CYLINDER ENGINES !!!!!!! Just had to gap down to .040"/1.0mm. The butt-dyno says YES, idle is smoother, MPG's are up (couldn't get more than 28 highway before, recorded multiple highway cruises on the NGKs at 72-75mph in the 30.X range!), and, oh yeah, did I mention they cost $2.50 per plug? The wallet also says YES. So run along now to your local auto parts store, where they are literally ALWAYS in stock (part #4435) and rejoice at the thought of walking out with 5 quality NGK copper plugs for less than $13.

I have tested the BCPR7EIX which did not make any difference to my car. I felt that the standard plugs worked well vs these.

DO NOT DO NOT DO NOT get laser series platinums! They are junk! I tried them out and our motors do not like them. I had so many issues with them I threw them away
