Intercooler Upgrades
Intercooler Upgrades: More Cooling Capacity for a Boosted Engine
An intercooler sits between the turbo and the intake, pulling heat out of the compressed charge air before it reaches the cylinders. Cooler air is denser and more knock-resistant, so a boosted engine that keeps intake temps down under repeated pulls holds its power more consistently. These intercooler upgrades cover the pieces that make that happen: larger and more efficient cores, replacement end tanks, mounting shrouds, and protection hardware. If your stock unit is heat-soaking on back roads or track days, this is the section that addresses it.
What ThreePiece Stocks
Right now there are 8 products on this page from 5 brands: CSF, Cusco, Perrin Performance, Mishimoto, and Vibrant. CSF makes up the largest share with four listings, mostly bar & plate cores. Current pricing runs from $43 for a Perrin intercooler stencil up to $529 for a CSF water/air core - that spread reflects what is in stock now, not a locked-in price.
On the core side, the CSF Water/Air Bar & Plate Core (12in x 6in x 6in) and the larger CSF High Performance Bar & Plate Core (22in x 12in x 3.5in) anchor the range. For custom or repair builds, the Vibrant end tank pairs with a horizontal core. Subaru owners will find the Mishimoto WRX top-mount shroud, the Cusco Impreza protection grill kit, and the Perrin FMIC stencil.
How to Choose
Not everything here is a full intercooler. The bare CSF cores are for builders fabricating or rebuilding an intercooler and need matching end tanks like the Vibrant piece - a water/air core versus an air/air core changes your whole plumbing plan. A shroud or top-mount shroud directs air onto an existing unit rather than replacing it. The Cusco grill kit and Perrin stencil are protection and dress-up items, not cooling upgrades. Decide first whether you're replacing a core, feeding an existing one, or protecting it, then match the physical dimensions listed in each product name to your bay.
What Else You Need
A core swap rarely stops at the core. Plan for connecting plumbing from Intercooler Pipes (125 products) and Intercooler Hoses (197 products). If you want a complete pre-built unit rather than a core, browse Intercoolers (215 products). To keep clean air heading into the turbo, look at Cold Air Intake Kits or the rest of the Air Intakes section.
Fitment and Ordering
Three of the eight products list fitment data, and the covered vehicles are all Subaru - the WRX, Impreza and STI, across model years 2008 to 2023. Bare cores and universal end tanks are sized by dimension, so confirm they physically fit your setup before ordering. All orders ship free, and Affirm and Katapult financing is available.
