Motion LS Steam Kit for Holley Lo-Ram Cathedral Port Intake 10-10040

Motion Raceworks steam kit for the Holley Lo-Ram is the solution to your LS1 coolant crossover/steam kit issues facing use of the Holley Lo-Ram Intake.

Because of how low this intake sits to the valley cover, it does not have clearance under the intake to run a proper traditional hard line steam kit coolant crossover setup. 

Parts are machined from 6061 aircraft aluminum. Also utilizes top quality Fragola lines.  This kit allows you to have a high flow 4 CORNER coolant crossover with a common manifold. 


This kit will only work with Cathedral versions of the Holley Lo-Ram intake

    Do not risk premature engine failure due to blocking off rear coolant crossover/steam ports.  These kits are recommended by nearly all aftermarket engine builders! (Fast 92 intake pictured).

    Note:  This kit comes with a -4AN male fitting to return coolant back to your RADIATOR.  No line is included as routing and length varies depending on application.  We always suggest running the coolant crossover return line to a fitting just below the radiator cap.  This allows the pressure and air to be sent to an area just below the radiator cap, allowing the radiator cap to release pressure as intended thereby removing the steam/pressure from the system.  Plumbing to the water pump risks reintroducing steam/air pressure back into the system. 

    Kit includes the following:

    • (4) Corner manifolds w/ steel AN fittings
    • (1) 5-Port Common Manifold
    • (1) Nickel Coated Steel T
    • (3) Black coated Fragola lines
    • All necessary hardware

    ***Note: No radiator return line included. 4AN line/fittings are available on our website.***
