DIY

First off, I would just like to encourage you with this: “These are easier to make than most may think.”

Proper activation of the secondary runners on the 5E-FHE's dual runner intake manifold is key to producing the most torque possible.  Without proper activation the manifold is not being used to its fullest potential, and lots of power is being lost.  Lets see how we can activate them correctly.

So, you finally bought that CT-9  you've been waiting for.  Now its time to bolt it on and have fun!  But, first you need a new turbo manifold, right?  You vaguely remember something about the 4E-FTE's manifold and its bad #3 cylinder runner.  Take a look inside and see whats needed to remedy that.

Spark plugs can tell us a lot about how our engine is running.  By looking at the tip of your plugs you can begin to figure out how well, or how bad, your engine is running.  Thanks to NGK we have these fine charts to use for reference.
