TGV Delete Kits


You and us? Cut from the same cloth, we are. The very fact that you’re shopping for a TGV delete means you could hang out with us at our shop and carry on a conversation without a hitch. Like us, you’re looking for every extra way to milk more power and performance out of your project car. We’ve spent collective decades doing the exact same thing. We don’t settle for stock: We stretch it and push it to new heights.

One of the ways we’ve found to do that in a Subaru WRX is by removing the tumble generator valve. There’s a lot of debate about what that thing is supposed to do. In theory, it helps reduce emissions at low speeds, which is pretty much the definition of daily driving around town, and also assists a cold or idle engine. But it sure looks to us like an obstruction to good air flow, and a way to get your check engine light to switch on more easily.

Removing it is advanced-level work, because most cases will require some custom tuning. If this is something you want to do, make sure you’re replacing it with a TGV delete kit made by one of the industry’s best manufacturers, such as IAG Performance, Aluminati or Mishimoto, in a variety of configurations.

We say this a lot, but it’s even more important for TGV delete kits: Contact us, tell us about how you want to drive your WRX and grill us with your most nitpicky questions. We’ll walk you through all the benefits and drawbacks, and help you with every phase of the project from installation to tune. At Modern Automotive Performance, we’ve earned one of the internet’s best reputations for customer service, and we’ll put that to work for you. And our Loyalty Reward program will put some extra cash in your wallet for your next big project.
