yeah the only issue is its very tight clearance near were the OEM oil sensor is...another alternative is one of these OIL Filter Sandwich Plate M18 Commodore V6 Adaptor Pressure Temperature Sensor | eBay
with a standard holden oil filter you should have plenty of clearance between filter and chassis rail, though Im not to sure Id trust em... prob leak or drop the pressure a tad
as above ^^^^^ all easy
get the sandwich plate for oil, just make sure u aren't one of those wanks that mount them in the vents.
do it in the compartment under the dash like mine here.
