2008-2009 Chevrolet Trailblazer 4.2L L6 Intake Manifold
Direct replacement intake manifold for your 4.2L inline-six engine. Built for durability and reliable fit. OEM-equivalent design restores proper air flow and engine performance.
Do I need to replace the gaskets when I install this manifold?
Yes. Always install fresh intake gaskets when swapping a manifold. The old gaskets will not seal properly on the new casting, and reusing them is a guaranteed leak. Pick up a gasket set rated for your engine.
What tools do I need to pull this off and install it?
You'll need basic hand tools—sockets, wrenches, and a gasket scraper. The manifold bolts directly to your cylinder head at factory points. Refer to your vehicle's service manual for torque specs and bolt sequence to avoid warping the new casting.
Does this come with new bolts or should I reuse mine?
Bolts are not included. Inspect your existing fasteners before reinstalling. If they're stretched or corroded, grab a new set—cheap insurance against leaks down the line.
