Vorsprung GLT™ TruSeal Intake Manifold Gasket Set, Audi Supercharged 3.0T (S4/S5/SQ5/A6/A7/A8/Q7)

Vorsprung GLT™ TruSeal Intake Manifold Gasket Set

The last intake manifold gasket set you will ever need to install.

If you own an Audi 3.0T supercharged V6, you already know "service position" is practically a hobby. Every time that supercharger comes off for a porting service, a thermostat, a PCV fix, or just curiosity about what's living under there, you only want to do the job once. Reusing flattened, crusty factory-style seals is how a routine teardown turns into a comeback vacuum leak.

The Problem: Generic Rubber Doesn't Survive the Valley of Death

Whether it's the factory gasket or a generic reman kit, the standard-issue intake manifold seals on this platform are molded from commercial-grade rubber. That material sits wedged between a hot supercharger snout and cylinder head, cycling through engine-bay heat on top and winter cold underneath. Over time it compresses, hardens, and loses its ability to spring back, which is exactly how a "while you're in there" job becomes a lean-code comeback a year later.

The Solution: Genuine Viton™ GLT Technology

We upgraded the material, not just the mold. Our TruSeal Intake Manifold Gasket Set is manufactured exclusively from Viton™ GLT, a peroxide-cured, low-temperature fluoroelastomer built to solve the exact failure mode that kills standard rubber intake seals on this engine.

• Stays Flexible When Factory Rubber Cracks: Standard FKM starts stiffening around -4°F (-20°C) and can crack on a cold start. Vorsprung GLT™ remains fully elastic down to -40°F (-40°C), so the seal keeps active sealing pressure against the manifold instead of pulling away from it.
• Holds Up Under Sustained Heat: Rated to +400°F (+204°C), well beyond what this engine bay throws at it, without the compression set that turns factory seals into hard plastic.
• Chemical Immunity: Peroxide cross-linking makes the polymer highly resistant to blow-by gases, oil vapor, and fuel vapor in the intake tract, resistance standard bisphenol-cured rubber can't match over the same service life.
• Made to Exact OEM Dimensions: Molds are formed to match the factory 079129717B/079129717D and 06E129717 gasket profiles, so it drops into the stock supercharger-to-manifold and manifold-to-head mating surfaces with no modification.
• Complete Kit: Everything you need to reseal the intake runners top to bottom after a teardown, in one order.

Key Specifications

• Material: Genuine Chemours Viton™ GLT (Low-Temperature FKM)
• OEM Matched: Molds made from the original OEM gasket profiles for an exact fit
• Temperature Range: -40°F to +400°F (-40°C to +204°C)
• Chemical Resistance: High resistance to synthetic engine oil vapor, fuel vapor, and blow-by gases
• Projected Durability: Engineered to outlast standard rubber seals by 2-5x, an estimated 15+ years of service versus the 3-5 years typical before a factory-style gasket compresses, hardens, and needs replacing

GLT™ TruSeal Intake Manifold Gasket Set FAQ

How is this different from your standard Intake Manifold Gasket Set?
Same fit and coverage, upgraded material. Our standard set uses a factory-style rubber compound; this TruSeal set is molded from genuine Viton™ GLT for the low-temperature flexibility and heat/chemical resistance standard rubber can't match, at a higher price point to match the material cost.

Do I need to replace these every time I remove the supercharger?
With standard rubber, yes, every removal. GLT™ TruSeal is built to survive many more heat cycles than factory-style seals, but we still recommend fresh gaskets any time the manifold comes off, cheap insurance against a comeback vacuum leak.

How much longer will this actually last than the OEM gasket?
Factory-style rubber typically needs replacing every 3-5 years, or anytime the manifold comes off, whichever comes first, since heat cycling and oil/fuel vapor exposure age it out. GLT™ TruSeal is engineered for 2-5x that service life, a projected 15+ years under normal use, so it's built to outlast the intervals when you'd naturally be back in there anyway.

Does this kit include every gasket needed for a full manifold reseal?
Yes, this set covers the intake runners top to bottom, matching the factory 079129717B/079129717D and 06E129717 gasket coverage.

Will this hold up in cold weather better than the factory gasket?
Yes. Viton™ GLT stays flexible down to -40°F, while standard FKM and factory rubber start stiffening around -4°F, which is exactly what causes cold-morning vacuum leaks on aging factory seals.

I'm installing Vorsprung's Artus-Sturm porting service or doing a PCV relocation. Do I need this too?
If the intake manifold has to come off to access those components, yes. Reseal it once with material that won't be your weak link again.

What tools do I need to install this?
Standard hand tools are sufficient, no special tools are required beyond what's needed to remove the intake manifold itself.

Complete Your Build

Frequently paired with this set:

• Vorsprung TruSeal High-Performance Oil Gasket Upgrade — reseal the oil filter housing and PCV breather while the front of the engine is already apart.
• Vorsprung TruSeal AFLAS Coolant Gasket Upgrade — cover the coolant crossover pipes and thermostat seals under the supercharger.
• Vorsprung GLT™ TruSeal PCV Valve Diaphragm Upgrade — for owners doing a PCV relocation while the manifold is off.
• Vorsprung Artus-Sturm Ported Supercharger Service — since the supercharger has to come off to port it, reseal the manifold in the same job.
