This is the most cost effective way to protect your rear cylinders on trucks under the 500HP mark. It addresses the restrictive factory intake manifold and the air starvation of the front and rear cylinders.
The Cross-Air adapts to existing ports at the front and rear of the intake plenum that are normally sealed off with a freeze plug style fittings from the factory. By splitting off the driver-side charge tube and creating two additional parallel paths to those ports, cylinders 1, 5, and 6 can be better supplied with air. This helps balance the engine temperatures and load at each cylinder greatly.
This entire package is fully TIG welded mandrel bent tubing, with a laser cut 1/2" flange and 1/4" dipstick mount. The intake manifold is standard equipped with two 1/8 inch NPT ports on the back for methanol/water injection, a boost gauge, etc.
This is a complete kit that includes instructions, machined cylinder head adapters, heavy duty 4-ply silicone couplers, stainless T-bolt clamps, an OEM gasket and hardware, and 1/8 inch port plugs for a quality install. For an additional charge, select powdercoating colors are available on this kit.
