Spark plug NGK or Champion

NGK are a good spark plug brand.

NGK plugs have never failed me at my shop. I'm pretty sure they're NGK 3199 plugs

i changed the plugs out for oem replacement NGK plugs (it had bosch platimun +2 in it) and a set of wires. and it ran just fine it was fixed. i then decided to swap my other coilpack back in and it ran fine no issues at all.

I put in NGK PFR7B plugs and R8 coil packs. Smoothed the idle out and judging by the butt dyno the rev/boost response seems great.

I run stock NGK with .026 gap as well and I've been anywhere from 10-18psi

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.

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'm at 60k figured, why not throw some new plugs in it for the hell of it. Ordered these as they're certainly not breaking the bank and again, reviews seemed promising. Now, immediately after turning the car on, (despite my disbelief when ppls said the car ran smoother) It actually did. My old plugs weren't in to bad of shape, nothing fouled up, gaps all looked the same, no excessive carbon build up and so on. When driving, engine truly feels very smooth but power doesn't seem as abrupt as it use to be. Before it would kick in and push you back, now its a slow, gradual kick. Almost feels as if I lost power. I have no way of determining how factual this is though. Fuel economy is roughly the same, if not a hair better. (based solely on my drive into work today) i received 24mpg as opposed to the 22-23 i normally get, driving no different than I normally do. Just wondering if anyone else noticed power loss or change in the feel of their car from these plugs. I'm seriously debating putting the old plugs back in, but I want to VAG COM my car first to see if I'm running any misfire codes.

I'm having the exact same problems with my 01 GTi VR6, ive replaced the coil pack and wires/plugs twice within 20,000ish miles...
