A heads-up. The 2006 LS2 like all of the older LS1/LS2/LS6 years takes the Delco UPF44, PF44 (now obsolete) or PF46 series filters or the aftermarket models that are compatible to 44 and 46 series. The 2006 LS7 engine was the first to changeover to the newer 48 series. The 2007 LS2 a year later converted to the 48 series. THEY ARE NOT INTERCHANGEABLE!!! The 48 series filters use a different mounting thread pitch. According to my notes, the M1-113 is compatible for the 48 series Delcos not the 44 & 46 series. M1 does make a 44/46 series premium filter and I seem to recall that it is M1-117 but check it in the catalog first before buying blindly.
