BMW e46 coil and spark plug replacement

[@adamsoloman5291]

You should remove the windshield cowel to get to those back ones!

[@daynebiehl9303]

Is that hard to do? I have a 325ci I’m about to do this on and have been dreading because of those back cylinders being covered up so much

Removing the cowel is easy. Just a few screws then pull it off

Hi, whats is the correct gap on those? I found out three different gaps sizes. 0.032,0.040 and 0.044. So i checked mine. Dound mine was gapped at 0.044, i tried the other two gaps. 0.032 was idlled bad and died. Then 0.040 was not good also. Put it back to 0.044 it was fine. But inwas buying new ones and was happed at 0.032. Now it makes me wondwr what is the right gap.

My 1998 320i e46 has an LPG fueling system added and I would like to change the coils and plugs, would the same coils still be used or do you think they'd be different ones? Thank you!

I would think so, but unsure.

Why won’t my car start after I did this

I just installed fresh coils and used the spark plugs used in this video with the anti seize and it is still misfiring, I read a post that says to not use anti seize on new spark plugs. Can anyone confirm the correct way to install spark plugs? And if my fresh spark plugs are now ruined because I used the anti seize

[@santiago1026]

According to FCP Euro's customer service: "It could be applied if you wish but we do not advise applying antisieze to spark plugs. Modern spark plugs have trivalent plating which prevents corrosion in the spark plug threads. This is also strongly discouraged by spark plug manufacturers such as Bosch and NGK"

[@santiago1026]

Another thing to note, a customer reviewed Bosch's spark plugs saying the following: "I changed out 60K mile OEM NGK plugs for these and had misfires under load after 20 miles. Took everything apart and found that the plugs loosened up. Retorqued them to 22ft-lbs and the same thing happened after about 20 miles. I changed these plugs out for the 60K mile used NGK plugs and everything is fine again. Not sure what the issue is with these coming loose" Make sure they aren't loosening up while driving
