GrimmSpeed TMIC Blow Off Valve Gasket for 2002-2007 WRX & 2004-2021 STI | 020023

Video description

Prevent boost leaks and ensure a secure seal with the GrimmSpeed Top Mount Intercooler (TMIC) Blow Off Valve Gasket. Designed for 2002-2007 Subaru WRX and 2004-2021 Subaru STI models, this premium gasket seals the connection between your blow-off valve (BOV) or bypass valve and the top mount intercooler flange.

Constructed with a reinforced multi-layer design, the GrimmSpeed gasket is three times thicker than the factory gasket and features an internal metal layer to help prevent blowouts under high boost, making it an excellent upgrade for both stock and modified Subarus.

Fitment:
Subaru WRX (2002-2007)
Subaru STI (2004-2021)

Features:
- Direct replacement TMIC blow-off valve gasket
- 3X thicker than the OEM gasket
- Reinforced internal metal layer
- Provides an optimal seal between the BOV/bypass valve and intercooler flange
- Compatible with OEM-style flange locations
- Works with many aftermarket blow-off valves using the factory flange pattern
- Sold individually

Overview  

Fitment Information:

2002-2007 Subaru WRX

2004-2021 Subaru STI

Features:

The GrimmSpeed Blow Off Valve Flange Gasket is a direct replacement of the OEM gasket to provide an optimal seal between your blow-off, or bypass, valve and the flange on your top mount intercooler. Not only is this gasket three times thicker, it also contains an inner metal layer which helps prevent blow-outs and overall creates a better seal for better protection against leaks. That's where the 3x thicker TMIC BOV gasket's extra thickness comes in handy!

  • 3 times thicker than the OEM gasket
  • Provides an optimal seal between your blow-off valve, and the flange on your top mount intercooler
  • Will work with other blow-off valves and aftermarket flange locations with the OEM flange type
  • Sold individually

Works perfectly, great fit.

Hard to take a picture of this installed but it does exactly as advertised. It survived the smoker test too with 0 leaks from that area!

It’s a great gasket.

Thicker than stock by a little. Definitely feels sturdier. I opted to use that than the turbo smart one that came with my hybrid valve.

Your average gasket. It was a bit stuck to the paper it is packaged in so I did have a hard time removing the small paper pieces from the gasket before the install.

Boost leak stopped!

This gasket stopped on of points of identified boost leak. I had reused the stock gasket a few times and subsequently leaked and could not be tightened any further. This thicker gasket is far superior and fully stopped the leak.
