Welcome to our MNJWS Intake Gaskets category, where you'll find top-tier replacement parts designed specifically for popular Chevy and GMC vehicles. If you're dealing with vacuum leaks, poor engine performance, or routine maintenance on your Silverado, Suburban, Tahoe, Sierra, Yukon, Savana, or Escalade equipped with 4.8L, 5.3L, or 6.0L engines, these intake manifold gasket sets are engineered to restore airtight seals and peak efficiency.
Why Choose MNJWS Intake Gaskets?
MNJWS has built a solid reputation in the automotive aftermarket for delivering high-quality, precision-engineered gaskets that meet or exceed OEM standards. What sets MNJWS apart is their commitment to durable materials that resist heat, pressure, and common engine chemicals, ensuring long-lasting performance even under demanding conditions. Unlike generic options, MNJWS gaskets are direct replacements for part numbers like 89060413 and MS98016T, making installation straightforward without custom modifications.
These gaskets are particularly valued by truck owners and mechanics for their ability to prevent coolant leaks, oil contamination, and compression loss—issues that can lead to costly repairs if ignored. Whether you're tackling a DIY rebuild or professional service, MNJWS provides the reliability you need to get back on the road quickly.
Key Features of the MNJWS Intake Manifold Gasket Set
Our featured MNJWS Intake Manifold Gasket Set is tailored for LS-based engines in Chevy and GMC full-size trucks and SUVs. It includes all necessary components for a complete seal between the intake manifold and cylinder heads, featuring:
- Multi-layer steel construction for superior durability and sealing under high torque.
- Precisely molded ports and bolt holes for perfect fitment on 4.8L, 5.3L, and 6.0L V8s.
- Resistance to ethylene glycol, oils, and fuels to prevent degradation over time.
- Easy installation with no special tools required, compatible with stock hardware.
This set addresses common failure points in these engines, such as warping from overheating or brittleness from age, helping maintain optimal air-fuel mixture and power output.
What to Look for When Shopping for Intake Gaskets
When selecting intake gaskets in the Intake Gaskets category, prioritize compatibility with your engine size and model year. Check for cross-references to OEM parts like 89060413 or MS98016T to ensure a seamless swap. Material quality is crucial—opt for MLS (multi-layer steel) designs over basic composites for better heat tolerance and reusability in some cases.
Consider your vehicle's mileage and usage: high-mileage trucks may benefit from gaskets with enhanced sealing beads to compensate for minor manifold distortions. Always inspect related components like intake bolts and throttle body gaskets during replacement to avoid repeat labor.

Common Use Cases for MNJWS Intake Gaskets
These gaskets shine in scenarios like preventive maintenance during upper engine rebuilds, especially on 1999-2007 Chevy Silverado and GMC Sierra models prone to plastic intake manifold cracks. They're also ideal for performance upgrades where tuned engines demand tighter seals to handle increased boost or nitrous. Off-road enthusiasts with Tahoes or Yukons appreciate the robustness against dust and vibration-induced failures.
If you're comparing brands, MNJWS holds its own against established names. For instance, while Fel-Pro Intake Gaskets offer premium pricing for racing applications, MNJWS provides excellent value for daily drivers. Similarly, options like ZONFANTAUTOPARTS Intake Gaskets cater to budget builds, but MNJWS strikes the perfect balance of quality and affordability.
