The Process West Radiator Cover is a functional engine bay upgrade designed to improve airflow management across the radiator while delivering a clean, finished appearance under the bonnet. It bridges the gap between form and function by enhancing both cooling efficiency and engine bay presentation.


Form Meets Function Cooling Design

A missing or poorly sealed radiator cover allows incoming air to disperse throughout the engine bay rather than passing efficiently through the radiator core. The Process West Radiator Cover addresses this by:

  • Directing airflow toward the radiator core
  • Reducing airflow leakage around the radiator support area
  • Improving overall cooling efficiency

The result is more effective heat exchange, particularly beneficial during:

  • Track driving
  • Spirited mountain runs
  • Hot climate conditions
  • Sustained high-load operation

Improved Thermal Consistency

By helping maintain consistent airflow through the radiator, this cover supports:

  • More stable engine operating temperatures
  • Reduced heat soak under extended load
  • Improved cooling system efficiency

Durable Construction & Finish

Manufactured from high-grade aluminium and finished for long-term durability:

  • Lightweight aluminium construction
  • Wrinkle coat powder finish (Black or Red)
  • High resistance to corrosion and wear
  • Built for long-term engine bay use

Straightforward Installation

Designed as a direct-fit engine bay component:

  • Includes all required installation hardware
  • No modifications required
  • Compatible with factory inlet chute setup

Key Features:

  • Improves radiator airflow efficiency
  • Helps reduce heat soak in demanding conditions
  • Lightweight aluminium construction
  • Wrinkle black or red powder-coated finish
  • Direct bolt-on installation
  • Includes all necessary hardware
  • Engine bay dress-up + functional cooling upgrade

Clean and adds a nice touch

I ordered this along with other engine dress up items on IIR. Wanted something more low profile without the huge logo. The quality is great, easy to install, and fast shipping! Adds a nice touch to the engine bay. Would highly recommend if you want something more low profile. Can’t beat the price!

Looks good, took some "adjusting"

Installed on my 2020 STI, and realized the rubber gasket has blocking almost half my intake. Played with the fitment as best I could before coming deciding to "influence" it the last little bit. Had to bend the left portion up slightly to get it to not conflict with the performance of the factory intake. There is the possibility it had a small tweak in it that I didn't notice before installation. Overall, looks good and installation was easy.
