Slant Six Intake Manifold Heater Kit

This product is designed for use with non-EGRMopar Slant Six intake manifolds, including Offenhauser 1x4bbl (PN5270) and 2x1bbl (PN 5041) intake manifolds.\

Do NOT order thisproduct if you have an Offenhauser 6019DP manifold for 240/300 inline6-cylinder Ford engines.  ForOffy 6227C manifolds, order our KIT0008.

Helps fuel distribution and minimizes off-idle bog by restoring a hot spotin the intake manifold floor. This product helps with cold operationeven with fully cold water because even cold water will counteract theevaporative cooling effect of vaporizing gasoline.  The heatreplaced by the water vaporizes any puddled fuel under the carburetorthat has fallen out of the airstream. For Offenhauser dual carburetorintake manifolds, the heater plate fits properly and ensures that eachcarburetor has its own hotspot.  

We are offering this product as a Basic Kitbut a Complete Kit (with silicone hoseand gear clamps) and as a Bare Kit withonly the plate itself are also available.  We recommendsplicing the plate into the return line from the heater core. Thisensures that cabin heat is maintained at all times in cold weather.

This plate is machined from 1/2"" 6061-T6 aluminum.  It boltsonto the bottom of the Slant Six intake manifold and has a machined-inpocket to match the bottom of the intake manifold.  The pocketpositively locates the plate without smearing the silicone seal andensures that the seal will not blow out.  Straight hose barbadapters (rather than elbows) are provided to ensure that the heaterhose clears the exhaust system without any contact.  The plateis equipped with threaded holes so that the plate may be easilyinstalled with 2 hands.  Once snugged-up, the bolts aresecured with lock washers and nuts.

The Basic Kit consists of:

  • 3 each of 5/16"" nuts, bolts, & washers
  • 2 each of 3/8"" NPT x 5/8"" hose barb adapters
  • detailed installation instructions

The Complete Kit includes the followingadditional items:

  • 10' of silicone hose
  • 6 each of 5/8"" ET-10 SS Gear Clamps

The Bare Kit consists of ONLY the plateitself.

We recommend the Complete Kit because ofthe heater's close proximity to the exhaust pipes.  Siliconeheater hose will not harden over time and will remain easily removableeven after many years of service.  The ET-10 gear clamps havean internal shield to prevent damage to the very pliable hose.

If you require starter solenoid mounting holes when using headers ortwin DutraDuals exhaust manifolds, please contact us tospecial order this item.

This product does NOTfit EGR-equipped manifolds without extensive modifications. For newer EGR-equipped intake manifolds, the intake manifold heater maybe ordered WITHOUT the pocket.  However, much more care mustbe taken when installing to ensure good adhesion between the intakemanifold base and the heater.  Please contact us for moreinformation.
