New Breather System for the 4.6L & 5.4L Engines ! !


     We now a have new and very efficient Breather System for the 4.6L & 5.4L Ford engines!  The new Breather traps both airborne oily deposits and oil that emits from the valve covers.  If left un-attended, it can cause many problems, most notably to the 03-04 Cobra engines, which suffer from blocked Inter-Cooler Passages, Carbon build-up on the back on the Intake valves, degraded intake track and many other issues associated with oil in the intake air flow like faulty sensor readings and clogged Idle air control motors.  This new system uses the best parts for the best results, AN-10 Hose and Fittings, Aluminum Catch Tank W/drain cock, and the whole thing bolts to your existing Terminator Engine.  While made especially for the 03-04 Cobra SC engine, it can be used on any 4.6L or 5.4L engine.  Also available in Black, Polished or traditional Red/Blue fittings.

Finally....A Book on How to Build a 03-04 Cobra Engine!!!



I know I have been asked a 1000 times, the same question.....Is there a Book on How to Assemble a 03-04 Cobra Engine?

Well Now There is !!

     We put together a great Book on How to Assemble a Cobra 03-04 " Terminator" Engine.  This book starts with the long block completed, and guides you through the step by step process of building your very own "Terminator" Engine.  In it, we not only guide you on the step by step process of the build, but also give detailed explanations of how the each part works and what it's part is in the over-all engine operation.  Besides the actual build, we also help guide you through the Wiring Process, and the installation of many Aftermarket Parts that are common to this engine.  In all, there are some 124 pages, with hundreds or Drawings, Pictures and Detailed Specifications to guide you through a problem free engine build.  We give all Torque Specifications for every part, with drawings and actual pictures of both the part your installing and where it goes on the engine.  You simply follow along as the Book builds a 03-04 Cobra engine, step by step, one part at a time.  The Book is supper friendly, and explains not only what the parts look like and where they go, but also why they go there and how they fit into the over-all design of the engine.

      If you're Serious about Building a 03-04 Cobra Engine, or just what to know more about how they work, this Book is a Must Have Item !
