Though Acura managed to equip the 2021+ TLX Type-S with a rather larger intercooler from the factory, there is always room for improvement, especially when adding power. We wanted to develop an intercooler upgrade that provides significant gains in terms of internal airflow volume and cooling without hindering turbocharger spool. After many weeks calculating a desired core size, optimal end tank fitment, all while avoiding CNC tooling constraints, we're finally able to order up a few custom cores for prototype sample testing.
Our TLX-S intercooler upgrade will utilize a 710mm x 125mm x 163.5mm core (in comparison to the the factory 595mm x 81mm x 127mm core) with billet machined end tanks. The hot-side inlet will utilize the factory ID for optimal spool. The cold-side will utilize a 3in OD to match the tubing in our Charge Pipe Upgrade Kit (which has an approximate ID of 2.87in or 72.9mm) for smooth airflow. To reiterate, our intercooler outlet has a flow diameter of 72.9mm compared to the stock 46.5mm.
Stay tuned for more updates to follow!
