THESE HIGH RAM INTAKES ARE A GREAT VALUE FOR THE COST--WE HAVE USED THEM ON MANY ENGINES AND THEY WORK LIKE A $3,000+ HOGAN OR WILSON, NOT LIKE SOME OF THE OTHERS OUT THERE. THESE ARE CAPABLE OF OVER 800HP NATURALLY ASPIRATED ON PUMP GAS IN THE RIGHT COMBINATION, AND WELL OVER 1500HP WITH POWER ADDERS!
