ARC BRAZING OIL COOLER KIT FOR TOYOTA GR86 ZN8 FA24 1T414-AA001

 

ARC BRAZING OIL COOLER KIT FOR TOYOTA GR86 ZN8 FA24 1T414-AA001

What we know of ARC 1T414-AA001

From its description:

• It’s water-cooled (i.e. oil cooled via coolant) rather than air-cooled.  
• Mounting position is between the radiator upper hose.  
• Uses AN10 oil lines.  

Advantages

Here are the benefits you’re likely to get by installing this oil cooler kit:

1. Lower Oil Temperatures Under Stress
   Because the oil is cooled via the coolant, the system helps reduce peak oil temperatures—important during track use, spirited driving, or hot ambient conditions. Keeping oil temps down helps maintain oil viscosity and its ability to protect engine components.
2. Improved Engine Reliability / Longevity
   Hot oil accelerates breakdown of additives, increases wear, and can contribute to heat-related issues. By keeping oil cooler, you reduce chances of thermal degradation, extend oil life, and protect internal parts (bearings, seals, etc.).
3. Better Oil Pressure Stability
   Cooler oil is more viscous (within normal operating ranges), so less thinning from heat. That helps maintain oil pressure under load, especially in sustained high RPM or cornering where oil is stressed. (Though note: adding lines and cooling parts sometimes can affect flow/resistance, but good design mitigates that.)
4. Reduced Load on Radiator / Engine Cooling System
   Since the oil heat is being handled partly by the cooling system (coolant loop), this can reduce heat load on the engine’s cooling system overall, as compared with oil-to-air external coolers which draw air and may add drag or require additional ducting or space.
5. Cleaner Installation / Packaging
   Because it’s water-cooled and uses coolant hoses, and the mounting is close to the radiator hose, installation tends to be more compact vs external oil coolers mounted ahead of bumper or in fenders. This can mean less modification to bodywork. (Depending on the design.)
6. Maintained Cold Start / Warm-up Function
   If coolant temperature is low, oil stays warm via the coolant. In many water-cooled oil cooler designs, the oil doesn’t over-cool (or stay too cold) during early warm-up, helping engine wear less at startup. (Overly cold oil at startup causes wear too.)
7. Uses Less Additional Hardware vs Full External Cooler
   Because you’re tapping into coolant lines, not installing a huge external radiator plus big brackets, you potentially have fewer parts, less plumbing, possibly less weight or simpler routing compared to full external air-to-oil cooler kits.

Possible Considerations / Trade-Offs (to be aware)

While you asked for advantages, it’s fair to know where things might not be ideal, so you can judge if it’s the right mod.

• Water-cooled oil cooler designs must be properly installed to avoid heat soak (i.e. when coolant gets hot so oil doesn’t get much cooling benefit).
• There’s risk of introducing another failure point ( hoses, fittings, adapters ), leakage, or coolant/oil contamination if not done well.
• If over-cooling (oil stays too cold), viscosity can be high, increasing friction especially in cold climates, possibly reducing fuel efficiency / increasing wear until warmed up.
• Slight complexity added to system: need to ensure compatibility with existing coolant routing and capacity.
