I edited that post with more points but they didn't make it!
My other point was that most of the aftermarket OEM replacements are made by the same companies, i.e. our Ford plugs are made by Autolite, the name on the side and dealer mark-up are the only differences. I also think there are a lot more factors that go into an engines workings than an ABS system. No to trivialize the system just pointing it out! When the sensors read a lock up the ABS kicks in. At least in our case! Granted the new BMW and Merc systems are much more comlpex than that.
I made some other point but that was 20 mins ago and I'm ... well I'll leave that alone!
