Harrop Engineering

This collection lists the Harrop Performance products we stock: intercoolers and a breather kit. Both are practical upgrades for 4WDs that tow, tour or cross water.

Intercoolers

An intercooler cools the air from the turbo before it enters the engine. A larger intercooler can help keep intake temperatures stable when you're towing, climbing or running a tune. Compare options in our front mount intercoolers range.

Breather kits

Diffs, gearboxes and transfer cases breathe as they heat and cool. When a hot diff hits cold water at a crossing, it can draw water in through the factory breather. A breather kit relocates those breathers higher up, out of the water. See all breather kits and diff breathers.

Plan the rest of the build

• A snorkel raises the engine's air intake for water crossings.
• A catch can helps keep oil vapour out of the intake.
• Check each product page for vehicle fitment.

Choosing parts

Harrop parts are vehicle-specific. Add your vehicle with the vehicle finder to see which parts are listed for it, and read each product page for the engine and model years covered. If you're planning a tune, ask your tuner whether an intercooler upgrade suits your setup.
