Fel-Pro Intake Manifold Gasket Set for Nissan/Infiniti V6 MS 97143 — Complete OE-Fit Repair Kit, Durable Seal

Fel-Pro MS 97143 is a complete intake manifold gasket kit engineered to restore a reliable seal on compatible Nissan and Infiniti V6 engines.

When intake manifold leaks cause rough idle, coolant loss, or poor performance, installing a purpose-built gasket set restores correct sealing between the manifold and cylinder head. The Fel-Pro MS 97143 kit is built for OE-style fit and durability, using application-specific materials and proprietary sealing features developed by Fel-Pro engineers and validated in real-world vehicle testing.

Which vehicles and engines will this gasket set fit?

The MS 97143 is intended for a range of Nissan and Infiniti models using the same intake manifold architecture. Always verify fitment with your vehicle’s year, make, model and engine to ensure compatibility before ordering.

• Compatible models include: 2007–2018 Nissan Altima, 2009–2020 Nissan Maxima, 2009–2020 Nissan Murano.
• Also fits select vehicles: 2013–2016 Nissan Pathfinder, 2011–2017 Nissan Quest, 2013 INFINITI JX35, and 2014–2016 INFINITI QX60.

How does Fel-Pro design this set to seal imperfect engine surfaces?

Fel-Pro designs gasket sets for the realities of repair work where sealing surfaces may show wear, warpage or minor damage. The MS 97143 uses tailored materials and engineered features to conform and seal where a simple flat gasket might fail.

• Application-specific elastomers and substrates that accommodate surface irregularities.
• Proprietary sealing beads and geometry to maintain compression under thermal cycles.
• Complete kit includes every gasket and seal required for the intake manifold repair unless noted otherwise.

What quality control and testing backs this Fel-Pro gasket set?

Parts in the MS 97143 set are engineered and reviewed by Fel-Pro’s development team and put through validation procedures designed to mirror on-vehicle conditions. This ensures the gasket performs under real driving conditions and installation stresses.

• Engineered and validated by Fel-Pro engineers through research and development processes.
• On-vehicle testing to confirm fit, sealing behavior and durability on the road.
• Manufactured with consistent production controls to meet repair-shop expectations.

What should I check before buying and installing this kit?

Verify part fitment and review any vehicle-specific installation notes before purchase. Proper installation practice and inspecting mating surfaces will improve sealing outcomes and long-term performance.

• Enter full vehicle information (year, make, model, engine and trim) in the fitment tool to confirm compatibility.
• Inspect and prep intake manifold and cylinder head surfaces for cleanliness and flatness prior to installation.
• Follow torque sequences and replacement recommendations during installation to avoid leaks.

Who is this for: The Fel-Pro MS 97143 intake manifold gasket set is aimed at DIY mechanics, independent repair shops and professional technicians working on Nissan and Infiniti V6 engines listed above.
