Legendex Big Boy Intercoolers

The Legendex Big Boy intercoolers are for the serious off-roader wanting the best from their 4WD turbo diesel engine.

Cool Under Pressure Move over kiddies - the Big Boys are here! Big, new, man-size plumbing so even the hardest working bloke (and his 4WD) can stay cool under pressure. At 48% cooler charge air temperatures than stock, you get up to 3 times more efficient cooling (results will vary between vehicles). That means better performance for towing, off-road and hillclimbs. A more efficient engine means better fuel economy and longer engine life.
