TWIN AIR Oil Cooling System for SUZUKI RMZ 450 2009

The TWIN AIR 160431 oil cooling system is designed for SUZUKI RMZ 450 2009. On a motocross or enduro four-stroke, the oil gets very hot in mud, sand or at low speed. An oil cooler takes the strain off the engine and protects the oil, which also lubricates the gearbox and clutch.

• 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.
