4-Bolt T4 Divided Turbo Manifold Gasket by GrimmSpeed

If you've dealt with sourcing turbo manifold gaskets before, you know that there are a lot of different options at a lot of different price points. Unfortunately, a gasket with stainless, multi-layer construction and guaranteed quality is nearly impossible to find. Until now.

At GrimmSpeed™, we have worked with endless amounts of aftermarket gaskets, but none seem to work as well as the multi-layer steel gaskets. The issue with most T4 gaskets is that even if they're multi-layer, they're not completely constructed of Stainless Steel which leads to leaks. Well, GrimmSpeed™ has your answer, a premium multi-layer stainless steel w/ stainless steel fire-ring gasket at a great price. Another thing that you'll notice is that we've opened up the bolt holes to 12.5mm and slotted them 5mm to ensure that you've got flexibility, even with custom-made turbo flanges or larger bolts.


  • 304 Stainless Steel Fire-Ring
  • 6x Stainless Steel Layers
  • Universal T4 Fitment


  • Turbo systems utilizing a T4 turbine flange (undivided)

What's In The Box?

  • 1 - 4-Bolt T4 Divided Turbo Manifold Gasket

Works great

Everything you'd expect from a gasket. It goes in, it seals, it makes you happy

Ryan Hughes
Better than I expected.

These were very nice steel shim gaskets. They were very thick for good compression and a tight seal.

Holds very well

The gasket came in a nice packaging and holds a nice seal. Haven't had any issues after installing this gasket!


Fits perfectly. You will need this

Required for Stage 2!

Don't waste your time installing a J-pipe without this. You will have a leak and spend a lot of time stressing and looking for the leak when you can just use this to properly install your J-pipe with your catback exhaust (or the stock exhaust using an adapter) and make sure there are no leaks.
