Lethal Performance 2011-2017 Mustang GT 18+ (now 21+) Manifold Power Package

The 18+ manifold power package for the S550 Mustang GT is proven to show BIG gains in NA and FI form.
We have customers reporting that they gained an amazing 25+ rwhp (peak vs peak) over the stock manifold and throttle body with just a cold air intake and cat-back! Not only that, this manifold drastically extends the power band and rev capability of the 5.0L without any loss in low end torque. Peak power is now made around 7200 rpm vs 6300 rpm with the stock manifold/throttle body combo and the usable power is carried to over 7500 rpm! Power gains of over 60 rwhp have been seen at 7200rpm+. The stock manifold has shown to fall off almost immediately after making peak power at 6300rpm.

On mildly modified vehicles running a gasoline based fuel, the stock fuel system is sufficient. If your car is a little more aggressively modded or plan to run E85, upgrading the injectors will be mandatory and in some cases, depending on other mods, a fuel pump booster may also need to be added.
