Ramair PRORAM SR Induction Kit – Toyota C-HR & Corolla 1.8 Hybrid (2016+)
The Ramair PRORAM SR Induction Kit (PSR-201) is a direct replacement for the standard airbox lid on the Toyota C-HR and Corolla 1.8 Hybrid. It is designed to improve airflow into the engine, giving a more responsive feel when you put your foot down, along with a more noticeable induction sound.
The standard factory air intake is built with cost and noise reduction in mind, not performance. By replacing the restrictive OEM airbox lid with this Ramair kit, you allow the engine to breathe more freely. The result is improved throttle response and a modest gain in performance – which, on a hybrid drivetrain, can feel particularly noticeable given how the engine and electric motor work together.
What’s Included
- Pleated PRORAM dual-cone performance air filter
- Precision-made aluminium MAF sensor tube (the MAF sensor – or Mass Air Flow sensor – measures how much air enters the engine, so a quality tube here is important for accurate readings)
- Cold air feed intake pipework
- Full fitting kit including all nuts, bolts, and brackets
- Step-by-step fitting instructions with images
Why the PRORAM Filter Makes a Difference
The pleated dual-cone filter design used in this kit offers a significantly larger filtration surface area compared to a standard flat-panel filter. This means more air can pass through at once, with less restriction, while still filtering out dust and debris that could harm your engine over time. It is a balance between performance and protection – not just an open, unfiltered intake.
The aluminium MAF sensor tube is precision-made to ensure an accurate, consistent airflow reading to your engine management system. A poorly made tube in this position can cause running issues, so the quality of this component genuinely matters.
What to Expect
On the 1.8 Hybrid, this kit is primarily aimed at improving throttle response and adding a more engaging induction note rather than delivering large power figures. Hybrid systems are complex, and while improved airflow does benefit the petrol engine’s efficiency and response, this should be viewed as a refinement upgrade rather than a significant power modification. That said, a freer-breathing engine is always a step in the right direction.
Installation is straightforward and does not require specialist tools. The included instructions are clear and image-led, making this suitable for a confident home mechanic.
Fitment Note: This kit is designed for the Toyota C-HR and Toyota Corolla fitted with the 1.8 Hybrid engine from 2016 onwards. Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific model before purchasing.
