The Katech Gen 4 LS Reverse Intake Valley Cover is designed specifically to support reverse-mounted intake manifold installations on GM Gen 4 LS engines. In reverse-intake configurations, the factory valley cover and oil pressure sensor orientation can interfere with intake manifold placement. This Katech valley cover resolves that issue by repositioning the oil pressure sensor for proper clearance.
This component is intended for specialty engine builds where a reverse intake layout is required due to packaging or system design constraints.
Designed for Reverse Intake Applications
Provides proper oil pressure sensor positioning when installing a reverse-mounted intake manifold on Gen 4 LS engines.
Oil Pressure Sensor Reorientation
Rotates the oil pressure sensor 90 degrees to improve clearance between the sensor and the intake manifold.
Gen 4 LS Engine Compatibility
Engineered for GM Gen 4 LS platforms when used with the correct sensor adapter.
Purpose-Built Katech Design
Developed to solve a specific fitment issue encountered during reverse intake installations.
GM Gen 4 LS engines
Applications requiring a reverse-mounted intake manifold
Correct oil pressure sensor adapter selection is required based on engine type:
LS2 & LS7 Engines
Requires Katech Oil Pressure Sensor Adapter – KAT-A4784
Not compatible with LS3 intake manifold clearance
LS2, LS3, & LS7 Engines (and applicable Gen 4 variants)
Requires Katech Oil Pressure Sensor Adapter – KAT-A6678
Failure to use the correct adapter may result in clearance or installation issues.
Intended for reverse intake manifold configurations only
Professional installation recommended
Always verify intake manifold and sensor clearance prior to final assembly
Since 1977, Katech Engineering has developed precision-engineered solutions for GM engine platforms, addressing real-world packaging and fitment challenges encountered in high-level engine builds.
