NGK › Spark plug

FWIW.....an electrical engineer friend of mine with a custom turbo BMW z-3 with over 500hp/500ftlbs at the wheels, did the homework and said NGK is one bad A$$ plug......he said unless you get into the really specialty racing plugs NGK is where it's at.....i say for the same money go NGK as soon as i get 20,000 on my 03 the NGK's you mentioned are going in for sure...$2.50ea was what i was quoted near me seems cheap enough compared to the $17ea BMW plugs i sell at work

Pros: NGK is one bad A$$ plug

Vehicle: BMW Z3

Mileage: 20000 km

Also I'm using the 3922's and love them. They went a long way in solving my timing pull probs w/ my ATP Stg3.

Pros: solving timing pull probs

Part number: 3922

It was time to change the plugs so I went for one range colder (from Autolite 3923 to 3922). Before I installed these plugs, the power would drop off dramatically above 5500 in 3rd, 4th, and 5th. Now it is a much more progressive decline. The car actually maintains that pushed back in the seat feeling in the upper revs now.

Pros: progressive power decline

Cons: power drop off dramatically

Part number: 3922

I've noticed something interesting about the NGK BKR6E's that I'm running. #1 - They respond extremely well to the chip and the N75 J valve. #2 - I've also lowered my gap from .032\" (stock spec) to .028\" to reduce the possibility of misfires under high boost. The bottom line is that the BKR6E at .028\" is a great plug for the 1.8T AEB motor.

Pros: responds well to chip, reduces misfires, great plug

Part number: BKR6E

The cheapo Autolite 3923 works very, very well. Works well with chipped and K04 cars also.

Pros: works very well, good for modified cars

Part number: 3923

I got W7DC spark plugs from the local foreign parts place...performance hasn't been ideal, and I've already looked at some of the other common issues; I'm considering new plugs in part due to fouling (bad CTS, drove with a failed CTS for too long, lots of carbon on the plugs...cleaned them up some, but I'm not convinced they're OK).

Cons: performance hasn't been ideal

I have a strong opinion in not suggesting the Bosch or the Beru. There is a reason that BOSH is no longer the OE spark plug in VW, Audi, BMW, Mercedes Benz etc., etc... Stick to the NGK, especially in a VR6, NGK has been OE since the intro of the VR6 six months after Bosh failed to produce a plug that would run in these engine during start up. The Bosch had nothing but running problems.

Pros: Stick to the NGK

Cons: Bosch running problems
