The JLT airbox isolates power-robbing engine heat by sealing to the stock hood scoop, using all the available air inlet locations. The box and tube's crosslink polyethylene material keeps the air cool as it flows to the engine. The huge air filter and tube produce a more aggressive sound than stock.
Extensive dyno-testing throughout the development of this intake kit ensures that it makes the most Horsepower possible. A stock Challenger 5.7L, had gains ranging from 10-15 HP.
