99.5-03 Ford 7.3L DieselSite 4x6 Intake Plenum Boots

 This kit includes the two boots that connect the intake manifold piping ("Spider") to the intake plenums on 1999.5-2003 7.3L PSD trucks.  Also included are four worm gear drive clamps. 

4in x 6In


   Stock boot material is silicone. However, this type of material is NOT oil compatible. This is unacceptable in our application as the Powerstroke incorporates a closed crankcase vent system. This means oil travels thru the intake and comes in constant contact with the boots. This oil contact causes deterioration and leaks due to the incompatibility of the silicone boots and the oil from your crankcase. In fact, if you have seen an oil mist all over the valley of your PSD and wondered where it was coming from, chances are it was caused by leaking, deteriorated stock boots. The stock boots WILL leak air and oil. In many cases, 3-4psi leaks are very common.

   As an added bonus, this boot kit will keep those who put out higher than normal boost numbers from "blowing boots". A Higher boost in the PSD can stretch the limits of a saturated set of factory boots and could blow your boots right off. In some cases, guys with numbers MUCH lower still running the stock boots saturated with oil, having lost their integrity and gripping ability can have their boots slip off as well. Not quite as dramatic, but still a bummer. Even a stock truck can have problems keeping boots on if they become saturated with oil.

   As with all of our DIESELSITE.COM "Originals", these are QUALITY PARTS. We ordered sample upon sample of hose material and clamps until we were satisfied with the quality of the parts and certain of their integrity in our application. Our boots are made of hose that is reinforced with synthetic fabric. It will not kink or collapse. The special synthetic rubber is exceptionally resistant to oil, heat, ozone, gasoline, gasohol, methanol, ethanol and diesel fuel. It can withstand engine heat and 100psi boost pressure. This is virtually "indestructible" boot material.
