Reviews of NGK spark plug

The plugs were only part of the problem. (They were NGK VW/Audi part#1010000035AB, NGK BKB5EKU. Good plugs, lasted forever. Sure, they needed to be replaced, but the #6 plug well must have been flooded a time or two before the radiator was replaced last month. The metal plug jacket had a lot of green crud in it. I cleaned the plug jacket with cylinder brushes from Harbor Freight ($7.00 without coupon for an assortment 3 sizes in SS and brass) and finished with medium emery paper wrapped around a thin long screwdriver. The motor runs smoothly now, across the RPM range, without hesitation.. I'm wearing a pretty wide smile.

Not sure what exactly your setup is/how well you have tuned for it, but on BKR7EIX plugs @ .028 and 25psi, I was encountering some spark blowout. Basically felt like the car dropped 2 cylinders, and my exhaust had muffled misfire sounds that basically sounded like a very fast skipping CD of fart noises lol.

Oh and I missed on letter on the spark plug it's BKR6EOUP. It's a NGK "R" type.

I ended up swapping coils/ICM and put new correct plugs in, and now it runs waaaay better.

I have NGK double plat and they have been great. Over 10k miles. Just put some in my girlfriends 2.5 jetta as well with no issues.

Use the NGKs OP uses with factory gap. All stock apart from Stage1 Superchips tune now on 95RON. No issues 'cept consumption's falling now cooler temps are here (46\u00baF yesterday afternoon SE London) from 40+ on lightfoot long run to 36MPG same motorway run

I've been running these plugs for over a year and a half and hate em, I guess when I got them I wanted new fresh plugs for a hot climate but should have taken them out immediately as there was noticeable power loss. I'm looking to go back to stock now as the car really ran much better. This is an unmodded 08 gti.

ngk Same as prof315-jeff,bkr7eix on both setups,supercharger and now turbo and they still work,my only mishap is i bought a set bkr8 and one fouled do to much gas @ idle,now with megasquirt no problems so far.

i know of several 2.5T and 2.0T (big turbo) running BKR7EIX gapped at 0.028"... Myself included, and no issues.

I am running those in my car now and they are perfect!!
