The stock heater tube has nipples that run coolant into and out of the throttle body. This causes the throttle body temperature to be increased due to the ~200 degree fluid running through it. This modified heater tube eliminates this coolant bypass through the throttle body. The stock section of pipe right there is also very restrictive, so this modified tube will have better flow through the heater core. The tube is ground smooth, sandblasted, and powdercoated black for a flawless better-than-factory appearance, and outfitted with a new viton o-ring.  This modified heater tube is one of the simplest ways to improve performance, and simplify the engine bay so it looks better and is easier to work on.

We've added different color options for the powdercoating to personalize your vehicle.  Please note that these other colors are a custom order, because we only do different color heater tubes as they are ordered, and for this reason, it will take a little longer to receive your heater tube.  Typical lead-time for a black heater tube is 1-10 business days depending on current inventory.  Typical lead-time for a colored heater tube is 10-30 business days because we have to put together an entire batch of that color to shoot that color to maintain our low prices.  Please contact mikem@milzymotorsports.com for questions regarding current inventory and lead-times.
