Cold Air Inductions Intake Systems

Cold Air Inductions intake systems have a simple goal--maximizing your vehicle's performance by keeping your intake air as cool as possible! First, every CAI intake is specifically designed and engineered for the vehicle it is sold for, resulting in maximum performance, an easy install, and a perfect fit. Next, their intakes are made of high-quality aluminum--not heat-absorbing plastic.

Sonnax Valve Body Reaming Fixtures

In certain applications there is no way to pilot a reamer to repair a worn valve body, forcing rebuilders to purchase new ones. This patented self-aligning fixture with specially designed tool kits allows these valve bodies to be repaired. The fixture provides an external rigid pilot bore for the reamer and guide pin. The self-aligning feature allows the fixture to be used on multiple valve bodies and valve bores. The fixture base is large enough to provide ample support for the valve body. Various transmissions locate some valve bores in the pump body rather than the valve body. These larger pump bodies do not readily fit onto the standard VB-FIX base plate. Sonnax offers an oversized pump base plate, VB-06, that allows large passenger vehicle pump bodies to be easily mounted and clamped to the VB-FIX for repair. Additional notes: * Patented, unique self-aligning device produces consistent, reliable results and eliminates the potential for reaming failures * Special tool kits have been designed to service a specific valve train bore, and must be used in conjunction with the valve body reaming fixture VB-FIX. Part numbers for these kits begin with an "F-" to distinguish them from the traditional Sonnax tool kits that can be used as standalone tools. * Contents: -- Base plate standard -- Clamp mounting plate -- Clamp plate round -- Outer races (2) -- Inner race -- Studs (3) threaded -- Washers (3) flat -- Wing nuts (3) -- Socket cap screws (4)

Sonnax Valve Bodies

Sonnax universal remanufactured valve bodies have been uniquely designed to fit a variety of '99-later Chrysler applications, regardless of OE checkball or solenoid configuration. The convenience of stocking one SKU number for various applications saves time, money and interchangeability confusion. The channel casting has been resurfaced to SAE recommended flatness and surface finish. The seasoned casting warpage is now eliminated, removing cross-leaks and manufacturing burrs that resulted in clutch distress and shift complaints. A new separator plate is also installed, along with gaskets, to seal the critical surfaces between the valve body and channel casting. Heavy-duty/high performance accumulator pistons with dual-guide seals are installed to prevent piston-to-bore scuffing and restore clutch pressures due to leakage. Patented Sonnax valves are installed to restore hydraulic pressures and eliminate shift complaints, trouble codes, converter concerns and overdrive clutch distress. Their patented accumulator cover plate—made from stronger, thicker material and secured with additional screws—is also installed to prevent flexing or breakage. To guarantee the highest level of operational performance, these remanufactured valve bodies are tested on state-of-the art equipment to verify that pressures match OE specification. Product notes: * One SKU fits all applications, saving time, money and confusion * Resurfaced OE channel casting eliminates warpage, burrs, and cross-leaks cost effectively * New separator plate and gaskets provide critical seal between cast surfaces * Patented Sonnax valves and pistons restore hydraulic integrity of circuits to eliminate shift complaints and clutch distress * Patented Sonnax accumulator cover plate stronger than OE to prevent flexing and breaking
