GM 3800 V6 Engine. I've had trouble with Wix filters leaking at the gasket before, so this time I decided to try the factory recommended torque spec which is 14 foot pounds. The torque wrench I used is a brand new Snap-on QJR117F inch pound torque wrench. I've used the same torque wrench previously to do the upper/lower intake manifold gaskets at 89 and 189 inch pounds respectively. No leaks from the replacement intake manifold gaskets. I will monitor the filter in the coming days, but 168 inch pounds feels really really tight. I kept hoping I would hear the click and I finally did.
