Includes the MAP sensor bung, bracket and seal, a 1/8" NPT accessory port, 3" silicone boot and stainless T-bolt clamps, new O-ring flange seals and an FPRV block-off kit for clearance to the fuel distribution block. Minimum T4 pedestal height is 5" with an S300 and 6" with an S400. Bridge only; the cold side pipe is not included.
