Originally posted by GoRan008@May 16 2005, 06:16 PM I would go with the OEM spark plugs. I changed mine not too long ago and everyone that I asked said to go with OEM. And if I recall, they were bit cheaper than Bosch Plat 4.

OEM always provides better power, economy for me. I would stay away from autolite though and try a BOSCH plug instead. Just my .02cents
I have bosch platinum +4. $36 spent.....and i dont notice a difference. It's just a peace of mind issue I had to do s I dumped a lil extra cash into it. I doubt it makes a difference and copper may be better.
I have used bosche super 4's and Splitfires on other cars and the splitfires made a noticeable difference even over good standard plugs on an Escort XR3I.
One thing I would say about BMW aftermarket parts is that they are rarely as good as the standard kit.
I read a review on air filters which was a report on quite a scientific test of all the filters available for E34s. I believe it was on a 525. The standard BMW filter flowed just slighly more than a K&N pannel filter but the K&N filter let it 5 times more dirt and grit into the engine than the standard filter. This was observed in the engine oil. So I guess this would drasticaly reduce the life of the engine.
From experience pannel filters make virtualy no difference, induction kits do but I think its best to leave it alone unless you are gonna do a full on proper job!
