JB4 #5 Misfire solved.. plug question..

Kuch335 · 08-20-2011, 03:02 PM

Started having cyl 5 misfires when the JB4 was on.. no problem when off.. so swapped the #5 & #1 coil and dropped a new plug from the dealer in #5 and all is well now. Going to get the full set of new plugs now, question is whats the difference, if any, between these two sets ?

Here's some pics of the one I removed.. have about 31k on the car now, 6k of it with me.. guessing prior owner had JB+ because the clip was already broke

Probably just get the Bosch, the cheaper one of the two, as the OEM plugs are Bosch also. I don't see the point of paying an extra $50 for the other ones......just my .02

Is that oil or gasoline on the thread of the plugs?

I personally wouldn't get anything from ECSTuning..they tend to have most parts for this car mixed in with the rest of the 3 series...i was shocked more than a few times actually

not really sure.. should the threads not be that dirty after 30k ? perhaps it was not screwed in tightly enough ?

Sometimes during oil changes oil will drip on the coilpak and make it's way down...

The difference is one has the BMW tax on it. Def change those plugs.

hmm.. got a misfire on #1 today.. guess it's the coil then.. picking up a new one tomorrow..

does the jb4 read afr from cylinder 1 cause i find it funny when i had my misfire in one there procede afr gauge would read zero when the dme shut the cylinder down that made it easy to fiqure out what cylinder it was with out pulling out the laptop

A Plug change is a good idea, and I usually recommend changing them every 20-25K when tuned. Its great preventative maintenance and if you DIY its pretty cheap
