Four-Valve Modular Engine Upgrades – Cobra Crankup

Testing ported heads, cams, and intake upgrade—plus nitrous—on a 4.6L Cobra Mod mill.
Originally introduced in the Mustang in 1996, the Four-Valve modular motor recently gained a new lease on life when Ford introduced the latest and greatest 5.0L version. With the new Mustang sporting a 5.0L and the Shelby offering the supercharged 5.8L, you have to ask—where does that leave the old 4.6L?

2011 Ford Mustang GT – Plug And Spray

We make 502 rwhp and run low-11s with a sneaky JMS Chip and Performance nitrous kit on an ‘11 GT.

Three-Valve Intake Manifold Dyno Test – Three’s A Crowd

Three intake manifolds for Three-Valve Mustangs
There is no question that the DOHC 5.0L Coyote engine has taken Mustang performance to new levels, and the spotlight, but if you have a Three-Valve 4.6L, there are still a lot of performance options available to increase the fun factor. Ported heads, larger camshafts, and boost can all take you to the next level—but even with an intake manifold as efficient as the stock one, performance can be limited.
