The VMP 3500 sensor is designed for larger housings (100mm and over) that need more range. It is a better solution than the HPX/5000 sensors which provide too much range in bigger housings. This is a direct bolt in for 05+ Fords, older cars will require a flange and pigtail (sold seperately on this website). Pigtails and adapter harnesses can be found here. Flanges for mounting this sensor directly into a tube can be found here. Entire housings for this MAF sensor can be found here. Tube Size Est. HP range with VMP 3500 sensor 4"/100MM 650-750RWHP, 113MM 800RWHP, 123MM 1000+RWHP, 127MM 1000+RWHP. This sensor can be used on any vehicle or computer system that requires a 0-5v input, there is also a resistance based temperature sensor built into the MAF that can optionally be used or left disconnected..
