the plugs are autolite platinums AP3924. the wires are the blue ignitors from techtonics. the rest of the ignition is stock. do i regap the plugs, or should i leave them where they are now. i'm leaning towards leave them since it ran fine before and i don't want to deal with a no start issue when i start it or the first time with the new cam.
I use Autolite plugs plat 1 cheepos that get me 400 miles per tank and seem to handle continuous high rpm output ( drove across the US in four days)
Now I'm running autolites one range colder than stock at .028 and they run great...
Last time I tried the 3922s and I was pleasently surprised with how smooth the car runs. I haven't had a misfire code since I changed over.
I bought some Autolite Platinums and now I find out they are crap Anyway, I needed something fast. Replaced them earlier this afternoon after work and so far so good. Acceleration is ALOT smoother.
My experience with auto lite has been complete trash, and their review ratings are always great. Anybody else have problems with auto lite plugs?
Throw them away, they're shit plugs. Autolite just didn't crack the code for making quality iridium plugs at a super cheap price. I wouldn't even put these in my lawn mower.
Don't buy Autolite spark plugs. They suck. I had 2 out of 4 in a pack that were faulty and failed within days of installing them.
When we got our 535xi one of the first things I did was visit the local parts place to buy new spark plugs for the N54. After driving the car a while and visiting many BMW discussion boards I learned most folks have a very low opinion of them
Autolite made the only plug I've ever had that was dead when brand new.
