Honda K series Pro intake **50 mm**
Our 50mm K-Pro intake is designed to work well with All motor builds in the 300 to 320 HP range with the addition of velocity stacks or boosted street motors under about 550-600 HP.
We've maintained the use of the stock placement 4 injectors to allow the use a stock style fuel rails as well as added bosses to the bottom of the runners for up to 8 injectors total. The bosses can also be machined for nitrous or water/meth.
The two piece manifold allows the use of either our end feed plenum or the side feed (Down facing - shown). Maintaining the two piece runner/plenum design allows easy porting or plenum volume changes without cutting and re-welding as well as the addition of velocity stacks using our optional velocity stack plate.
We can use any throttle body you want to run, add nitrous, port and polish, lengthen the runners to meet your calculations, we can even powder coat the outside or polish the plenum for hot looks.
We've eliminated all welding to keep the price down and eliminate the fear of weld leaks or breakage but kept all the advantages of this style manifold.
The manifold is available in both water port and non water port. We can also thread a 3/8" NPT port in the Z3 flange for the water port to use a hose barb, just let us know when you place the order. If you're not sure if you have a water port head or not, you can send us a pic. K20A, K20A2, K20A3 will have the non water port flange or short flange. The K24A2 and K20Z3 have the long water port full flange.
This manifold is not known to bolt on to the K24Z3/Z7 head and doesn not have the same size injector bosses!!
We also offer a throttle cable bracket if you're running the Q45 throttle body, part number UI-Q45-TCB-S1. Most applications will work with an EP3 throttle cable. The cable will have a bit of extra slack that can be taken up at the gas pedal with a cable clamp.
