4 X 4’s, typically, see a combination of off-roading, towing, hauling and a variety of strenuous uses regular vehicles don’t encounter.
This “extra” duty can easily strain your 4 X 4’s cooling system, raising temps:
1) In the engine
2) Under hood
3) And in the cabin.
That’s when you need RunCool Hood Louvers! Hot air rises – let it out with our Desert-Proven™ Hood Louvers, as proven and used by the U.S. Border Patrol, Dept. of Homeland Security and many off-roaders and racers across the U.S. and around the world!
Our Hood Louvers lower underhood temps by 47° (per police testing) and lower your operating temp – owners report drops of up to 27° on the engine temp gauge!
This means cooler intake temps – which yields more power, thanks to a denser intake charge.
The cooler underhood temp means longer life for under-hood components – belts, hoses, sensitive relays and sensors, ABS Controllers – even the battery.
The lower operating costs mean RunCool Hood Louvers pay for themselves over time!
