This triggers a question (or concern..).
In fact I've used k&n on numerous other car and did not have any problems at all.
But I've read about the k&n filter for boxster and the problems it caused with the MAF. So this time around, I opted for a BMC filter, since there are a number of boxsters on BMC filters.
Frankly, the BMC and k&n filter looks similar in build and both uses oil on the cloth element, except the filters are different in color.
So why is it that a number of people recommend BMC ? Do they use a different kind of oil ? The construction doesn't look any different from k&n ?
Anyone ? Or will the bmc filter cause the same problems as the k&n ?
