It's one of those things where the products don't always have a quantifiable improvement. It's not like flashing your AP to Cobb Stage 2 from stock and noticing an immediate difference.

The products and solutions offered are rather expensive, and not all LGTs have issues with massive amounts of PCV oil consumption. Subaru engineered a catch-all solution in their PCV system that DOES work, but it does have side-effects.

Personally, I don't like having oil in the intake tract, so I opted to put Moroso AOSes on my car.

A good reason NOT to bother with an AOS... "if it ain't broke, don't fix it." If I hadn't seen a lot of oil inside my TMIC on both my STi and my LGT, I wouldn't have bothered with an AOS either.
