This is our Side Feed plenum design with Q45 throttle body pattern commonly used in bottom feed manifold designs such as our Honda K-Pro. The main flange is drilled and tapped for our bolt on plenum design, you can use one of our plenum flanges and easily put the pieces together to meet your needs or give us a call for a custom manifold estimate. We’ve tested our bolt on flange to over 100 PSI. We’ve also set it up with clearance to accept our 4 port velocity stack plate when bolted to a flange making velocity stacks an easy, affordable option in your custom intake build.
The plenum has a 3.5 liter volume and 4 – 1/8″ NPT port for vacuum fittings. The bolting flange is threaded for 10 – 6mm bolts.
Q45 throttle body, throttle cable bracket and velocity stacks sold seperately.
