Product Summary
Details

DIY FABRICATION KIT ONLY

This kit is designed for fabricators looking to build their own intake manifold for medium-large turbo setups on virtually any 4 cylinder engine with adequate room for the plenum. Designed to bring our performance-leading cast plenum and velocity stack design for the VW/Audi 1.8T engines to any 4 cylinder build. This kit allows options to assemble the intake manifold portion up to the runners. Fabrication of the engine flange, fuel injectors, intake runners, etc... will be required to be fabricated and welded separately and is completely dependent on the engine and chassis being used. The DIY fabrication nature of this kit is perfect for those looking to build a custom swap, large power, or building a unique engine/platform with little or non-existent aftermarket manifold support. Please ensure you have the ability to fabricate and/or source other needed parts/flanges before ordering.


AVAILABLE KIT OPTIONS 

  • IE cast aluminum intake manifold plenum & hardware
  • Multiple Plenum throttle body flange sizes available 
  • IE CNC machined aluminum intake manifold flange
  • IE MIcro Vacuum Manifold

 

IE CAST MANIFOLD PLENUM

The IE cast aluminum unique modular symmetrical designed manifold plenum allows placement of the throttle body on either side of the engine.  The plenum has been very carefully engineered and digitally optimized to distribute airflow evenly to all 4 cylinders regardless of the loading conditions. Each manifold plenum is cast, machined, inspected and packed all in the USA. The plenums are cast from a special self-aging and self-hardening alloy with strict requirements for chemical composition. Top of the line Japanese machining centers machine all major surfaces of the parts in one setup, ensuring a perfect fit, finish, and maximum value.

Available Throttle Body Flange Sizes 

  • VW/Audi 1.8T stock size 60mm flange
  • Dodge Hemi 80mm flange

 

IE CNC ALUMINUM PLENUM FLANGE

Designed for a perfect fit with maximum airflow, the IE Aluminum Plenum Flange is the perfect solution for fitting the matching IE Cast plenum to custom welded runners using RMR oval tube.  CNC'd in-house from one solid piece of aircraft grade aluminum, the plenum flange is tuned for medium to high RPM power.  Carefully designed and flow tested velocity stacks deliver more air to the cylinder than any other intake manifold runner flange design on the market. The plenum port spacing is 88mm.

IE MICRO VACUUM MANIFOLD

This simple fitting provides all of the vacuum sources needed for most any setup without the worry of drilling into your IE plenum. Eliminate the need for drilling, tapping, cluttered lines, or ugly fittings on the manifold. This innovative vacuum fitting fits directly to the IE plenum using supplied 3/8 NPT threads and can be installed to face any direction.

Fitment

This is a universal product designed for fabricators and engine builders as a DIY solution on inline 4 cylinder engines. 
Be sure to check the size chart and make sure you can source or fabricate the rest of the needed flanges and fueling setup before ordering.
