I didnt know what to make for the title of this thread. Anyways, there is a more-subaru specific site, which sells sender units for oil pressure and temperature. Instead of tapping the block or oil pan, this adapter is sandwiched between the oil filter housing, and the oil filter. I was wondering if this would work on a 7m or not, if anyone knows about the WRX/STI enough to make a comparison i think this would be really helpful to the MKIII croud. Here is a link to the product. http://www.daddysscp.com/dcart4/product.php?productid=109&cat=13&page=1
