If I had to buy again, I wouldn't.

Box was opened, missing brass hose fittings and spring does not close better when cold. The device has a thermostat cooling system. with spiral spring , no bimetal

Pros
  • Type E sandwich adapter 3/4"-16 thread size
Cons
  • Does not fit all

Revainrating 4 out of 5

Terrible. The filter mounting surface is not vertical.

Terrible. The filter mounting surface is not perpendicular to the oil filter axis, resulting in oil leakage. I've tried different brands of filters, all of which threw out massive amounts of oil when working.

Pros
  • Oil filter factory equivalent saved
Cons
  • Crumpled packaging

Pros
  • Provides external oil lines for oil cooler without moving the factory oil filter
Cons
  • Available in black only

As long as it works well I don't know.

So far so good, I don't know if the 'thermostat' function works or if the adapter is in the 'always open' state. I installed this on a 2009 Toyota Tacoma 4.0L engine. I don't know the exact temperature difference, but it was only added as an additive for engine oil durability.

Pros
  • High quality cast aluminum
Cons
  • Low repairability
