Thumbnail Filmstrip of 1999.5-2003 7.3L Powerstroke Intake Manifold Sinister Diesel SD-INTEL-7-3-BK Images
The Sinister SD-INTEL-7-3-BK is a Sinister Blue aluminum intake elbow for a 1999.5–2003 7.3 Powerstroke. It replaces the cast factory Y-pipe with larger-diameter mandrel-bent tubing and a wider radius, so the charge air is not pinched on the way to the spider.
The tubing is TIG-welded aluminum. The flanges are CNC-machined billet and bolt to the factory locations. The larger section is what Sinister uses to hold higher boost than the stock casting. Up to four 1/8-inch NPT bungs can be added for methanol, nitrous, or an intake-temp probe. Hardware and a high-temp silicone boot kit are included. It is backed by Sinister’s lifetime warranty.
It fits late-1999.5 through 2003 F-250 and F-350 7.3 trucks. Early 1999 trucks use a different turbo outlet. It is not for sale in California.

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.
