TWIN AIR Oil Cooling System for YAMAHA YZF 250 2024-2026

The TWIN AIR 160429 oil cooling system is designed for YAMAHA YZF 250 from 2024 to 2026. This kit adds an oil cooler to a four-stroke engine: an air-cooled heat exchanger through which the engine oil flows. The oil runs cooler and keeps its lubricating properties better when the engine is working hard.

Key features

• Patented air-cooled oil cooler, independent of the coolant circuit.
• Tubular heat exchanger mounted behind the left radiator, connected with rubber hoses of 6 mm inner diameter.
• Complete kit: heat exchanger, bolts, oil filter cap, hoses, clamps and instructions.

When do you need it?

• Riding in sand, mud or slow enduro, where the engine runs hot.
• Tuned or hard-worked engine.
• Oil that breaks down quickly between changes.

The kit is specific to each model: check the bike and years. Quality engine oil and regular oil changes are still essential.

Fitting tips

1. With the engine cold, drain the engine oil.
2. Follow the instructions: mount the cooler in its intended location and connect the hoses, with no kinks and no contact with hot or moving parts.
3. Tighten the clamps, fill with engine oil, run the engine, then check the level again: the added circuit holds oil.
4. Check for leaks after the first ride.
