If you're looking to swap out that flimsy stock intercooler, the GrimmSpeed Top Mount Intercooler Kit is where it's at. Seriously, that plastic factory intercooler just doesn’t cut it, especially if you’re cranking up the boost. The stock FA20DIT TMIC does a decent job for daily driving, but once you start pushing those boost levels, things can get dicey. Higher post-turbo air temps can lead to pre-detonation, or as we like to call it, 'knock,' which is definitely not what you want when you’re trying to make power.

This intercooler is built to handle the heat and keep those charge temps in check, even when you're driving hard. It’s got cast aluminum end tanks that are tough as nails, and a large bar and plate core that really helps with cooling efficiency. Plus, the TIG welded construction means it’s built to last. You’re not just getting a performance upgrade; you’re getting peace of mind knowing it’s solid.

• Cast Aluminum End Tanks: No more worrying about cracking or leaks.
• 5-Ply Silicone Couplers: These bad boys are durable and help maintain a tight seal.
• Fully-Integrated Two-Piece Splitter: This design helps with airflow and keeps things streamlined.
• Vibration Isolation Mounting: Keeps everything steady, even when you’re pushing it to the limit.

Now, if you’ve got a Subaru WRX from 2015 to 2021, this intercooler is a perfect fit. It’ll clear those pesky 35s with just a bit of trimming if you’re looking to go big with your tire setup. So, if you're ready to take your WRX to the next level, the GrimmSpeed intercooler is a solid choice. It’s all about keeping your engine happy and making sure you can push it without worrying about heat issues. Trust me, your ride will thank you.
