If you’re diving into the world of performance upgrades, you probably already know that a good intercooler is key to keeping your engine happy. Let’s talk about why this 90027 GrimmSpeed Top Mount Intercooler Kit is a solid choice for your Subaru Legacy GT or Outback XT from 2005 to 2009.

When your turbo kicks in, it compresses the air, which heats it up. This isn’t just a side effect; it’s a physics thing. The tighter those air molecules get packed, the faster they move and the hotter they become. That’s where this intercooler comes into play. By removing heat from the intake air, you’re making it denser, which means better combustion and more power without the dreaded knock. Your stock intercooler might handle things fine at factory boost levels, but once you start pushing it, it can’t keep up. That’s when you’ll notice heat-soak, and trust me, it’s not pretty.

What’s in the Kit?

• Core Size: The 17.5in x 8.7in x 3.5in cross-flow core strikes a balance between high heat transfer and low pressure drop. It’s designed to keep the air flowing smoothly while cooling it down.
• End Tanks: These are cast aluminum with a machined BPV flange for a precise fit. No more worrying about leaks!
• Couplers: The 5-ply silicone couplers are custom molded and reinforced to handle the heat and pressure of your turbo setup.
• Wide-Mouth Splitter: This feature collects air from the entire width of the scoop, maximizing airflow.
• Mounting: Vibration isolation mounting helps protect the intercooler from wear and tear over time.
• Studs: Stainless steel BPV studs mean you don’t have to stress about damaging those fragile aluminum threads.
• Prepped for You: Each unit is cleaned, inspected, and sealed before shipping, so you won’t have to worry about any foreign debris causing issues down the line.
