I purchased these Torx Safety bits from Sears over the weekend. It makes it real easy to take the sensor off of the housing for cleaning or modifying the actual housing(removing the sampling tube). Not sure if this has been posted already, I thought it would be useful to many...<ul><li><a href="http://www.sears.com/sr/javasr/product.do?BV_SessionID=@@@@0875548702.1086105392@ @@@&amp;BV_EngineID=cckeadcljdmdmllcehgcemgdffmdflk.0&amp; vertical=TOOL&amp;pid=00925702000&amp;bidsite=CRAFT&amp;vertic al=TOOL&amp;com.broadvision.sess

He's got only two tools on him when he shows up: big-ass channel locks and a big-ass hammer. Oh, and he usually attempts to borrow my screwdriver. :-P

that takes a 2.5mm allen wrench to install/remove. Thats the reason all S3 MAFs leave here with stainless sensor mounting hardware.

I spent the night in Chugwater Wyoming (if ya don't believe the name look it up) with my TT waiting for them to get a tamper-resistant Torx wrench in after the part arrived. The part was in-stock in Cheyenne. But there was no TR Torx bit in the entire state of Wyoming!!! Had to buy one out of state and buy it a plane ticket. No more TR Torx for me, EVER!! On ANYTHING!!
