Again I say that they (motorcraf filters) are not "bad" but that there might be better filters for the SVT due to the increased oil presure resulting from the increased rpm's to reach higher engine power. When pump rpm's (engine is a pump) are increased the oil flows faster within the engine, thus increasing the oil pressure. It must. Another example, take the non SVT and SVT and see where are the rpm's for a given gear and you will see that SVT are higher for a given gear. And as for the redline. Well let me say this, some time a go I had a MB 190, with a 90 HP engine. The max power was on 5100 rpm's, while the redline started at 6000. So redline is just the place where one should not bring it's engine (hence the rev limiter) not allways where the max power is. It is Itallian cars that are mostly redline/max power. So to answer your question if you are driving an non SVT and are regularily taking it past it peak power rpm;s all the way to the redline, you are just wasting fuel, engine and time because nothing happens there except your bills increase. Besides, uprated engines require uprated parts. Filters are just some of those.
