Because of the angle of the drain hole, the F108SX outlet hole is always going to point at an awkward parallel angle to the skid plate hole. Although unlikely, if something catches on the body of the valve it also has infinitely more leverage to tear it off compared to the fixed stubby bodies of the non SX models.

The F108 and F108S both point in the direction of the drain hole, perpendicular to the skid plate hole as intended. The F108 has no nipple and is the safest, flushest valve. The F108S has a tiny nipple adapter that nevertheless does not significantly decrease clearance, and you can connect a plastic nipple with a hose to fill a gallon jug directly with zero risk of spilling a drop of oil. I have the F108S installed in my car and it is tucked well beneath the skid plate hole.

tldr; do not get the F108SX for our cars. get the F108 or F108S with 16mm-1.5 thread size. If you buy the F108S, also buy the 3/8" ID (inner diameter) clear hose and the plastic nipple adapter for extremely easy and clean oil changes.

All too true. Too soon old - to late smart.
