Sinister SD-INTEL-7.3-BK Intake Manifold

The following is my review for the Sinister Intake Manifold set that I recently purchased from Full Force Diesel: Full Force Diesel Performance was excellent to work with! They had the Sinister intake manifold set for my vehicle in stock (2002 Ford F-350 7.3 Liter Diesel). Sinister actually told me that they were behind about 4-6 weeks if I ordered the intake manifold set direct from them. The Sinister intake manifold replaced a partially cracked stock Ford spider/intake manifold, and WHAT A DIFFERENCE! The thick black exhaust disappeared, turbo lag decreased dramatically, power is up by about 1/3 and my fuel mileage also increased. Another benefit of the Sinister system is that it includes all 8 new turbo hose clamps...those would cost about $25+ each if purchasing them separately, and their quality is superior to the stock hose clamps. This made the Sinister intake manifold purchase a better buy than the competitive products.
