Spark plug Bosch or NGK

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

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!!

Personally I prefer NGK and have had excellent results on our customer's cars with NGK. They make a great plug.

So far we have; Changed to new spark plug wires, distributor cap and rotor and the distributor is not leaking oil, tried two different sets of spark plugs Bosch F6DTC and NGK/RIDIUM BKR6EIX.

I changed over to the BKR7E model to see how they worked. I wasn't impressed because after that the RPMs on my tach wouldn't stay steady at idle.
