There are several reasons it might not be. Here's a few :
1) anti-drain back valve (basically a check valve that prevents oil flowing
back out of the engine through the pump when the engine is not running).
2) bypass valve (to allow oil to flow around the filter when the filter is
clogged). TRs don't need this, it's already in the filter head.
3) Filter flow rating.
4) Burst strength
