Lskioer Intake Manifold Gasket Set for Chevy GMC 4.8L/5.3L/6.0L – 2-Piece Rubberized Seal, OE Fit

Lskioer 2-piece intake manifold gasket set seals the intake manifold to cylinder heads on GM 4.8L, 5.3L and 6.0L engines to restore vacuum integrity and prevent leaks.

If your Chevy, GMC, Cadillac or related GM vehicle is showing symptoms of vacuum leaks, rough idle, or coolant/oil seepage around the intake manifold, this Lskioer gasket set is a direct-fit aftermarket replacement for OE part numbers including 89060413 and 89017589. Designed for workshop use, these gaskets use a rubberized compound to maintain a resilient seal under thermal cycling, exposure to oil, coolant and EGR gases. The set is sold as two pieces and fits a wide range of models powered by GM 294 (4.8L), 325 (5.3L) and 364 (6.0L) engines.

Which vehicles and engines will accept this gasket set?

This Lskioer intake manifold gasket set fits many GM cars and trucks that use GM 4.8L, 5.3L, and 6.0L V8 engines. Confirm fitment by cross-referencing the listed part numbers or your vehicle’s engine code before ordering.

• Compatible models include Chevy Silverado, Tahoe, Suburban, Avalanche, Colorado, Express, Trailblazer and SSR.
• Also fits GMC Sierra, Yukon, Sierra, Envoy, Canyon, Savana and C3500.
• Other compatible makes: Cadillac Escalade, Buick Rainier, Oldsmobile Bravada, Hummer H2/H3/H3T.
• Engine families: GM 294 (4.8L), 325 (5.3L), 364 (6.0L).

How does this gasket set improve engine performance and reliability?

By restoring a consistent seal between the intake manifold and cylinder heads, the gasket set prevents unmetered air and fluid leaks that upset the air–fuel ratio and vacuum systems. That support helps stabilize idle, reduce misfires, and maintain correct intake vacuum while protecting surrounding components from leaks.

• Rubberized compound resists hardening, cracking, and leaks under heat.
• Designed to seal imperfect surfaces typical in repair scenarios.
• Helps preserve correct air-fuel mixture and throttle response.
• Reduces noise and heat transfer from the intake assembly.

What materials and quality standards are used in these gaskets?

The gaskets are engineered to meet or approximate OEM performance using a durable rubberized sealing compound and stable backing materials. They are intended for the repair environment where surfaces may not be factory-flat and must withstand typical underhood contaminants.

• High-quality rubberized compound resists oil, coolant and EGR exposure.
• Stable construction endures thermal cycling without premature hardening.
• Manufactured to replace part numbers: 89060413, 89017589, 17113557, MS92211, MS4657, MS18007.
• Trusted by mechanics as a practical aftermarket replacement option.

How do I install the Lskioer intake manifold gasket set and what should I watch for?

Installation requires removing the intake manifold, cleaning mating surfaces thoroughly, and following the vehicle manufacturer’s torque sequence and specs. Use new gaskets only and inspect mounting surfaces for warpage or damage; improper installation can allow leaks to persist.

• Clean and de-grease all mating surfaces before fitting gaskets.
• Follow factory torque sequence and recommended torque values.
• Replace any damaged bolts, studs, or seals encountered during removal.
• Test for vacuum and coolant leaks after reassembly before road use.

Who is this for: This Lskioer intake manifold gasket set is aimed at DIY mechanics and professional technicians repairing GM V8 engines (4.8L, 5.3L, 6.0L) in trucks and SUVs. It’s suitable when you need a reliable, workshop-grade replacement for failed or leaking intake gaskets that restores engine vacuum, reduces noise, and prevents fluid seepage without the premium cost of some OE parts. Always verify part numbers and engine compatibility for your specific vehicle before purchase.
