On late model TDIs they ruin MAF sensors. Even a very slight over oiling kills a $150+ sensor. I ran one in my Dakota for awhile, I could see no real performance or economy gain. I'd like to try blind tests to see if somebody could tell. Kid next door has a Mustang, I wonder if he'd be into the idea. Curt
