PRL.1109.1.0 - PRL Motorsports 4847RS Drop-In Turbocharger Upgrade - Honda Accord 1.5T (2018-2022)

When we set out to develop a turbocharger for the 11th Gen 1.5T, the goal was simple: deliver real power gains without compromising the drivability that makes this platform so enjoyable every day. The result is a true drop-in turbocharger upgrade that installs seamlessly in place of the factory unit, requiring no additional hardware modifications, but delivers explosive responsiveness behind the wheel.

This isn’t a “big turbo” that sacrifices spool for peak numbers. We engineered this unit to come on strong early, with stock-like spool characteristics, while unlocking substantially more power throughout the rev range. It’s designed to maximize the power potential within the factory turbo footprint, giving drivers the ability to push their build further without stepping into a more complex setup.

The balance between performance and usability is what makes this turbo stand out. Whether you're daily driving or pushing the car harder, the experience remains smooth, predictable, and consistent, with noticeable gains where the factory turbo begins to fall off.

For those looking to get the most out of the 1.5T platform while staying within a direct bolt-on configuration, this is the piece that helps take your build to the next level.
