Both have their benefits and drawbacks, and the right choice will depend on your specific needs and goals. In this section, we will discuss the advantages and considerations of upgrading your intercooler, helping you make an informed decision for your WRX STI.
Benefits and Considerations
Improved Turbo Efficiency - The primary benefit of installing an aftermarket intercooler, be it a top mount intercooler or front mount intercooler, is its ability to cool more air than the stock intercooler. This leads to a denser air-fuel mixture, which can improve combustion efficiency and ultimately result in better engine performance. If your Subaru WRX STI has undergone other performance modifications such as installing a larger turbocharger, increased boost, or implementing an aggressive ECU tune, an upgraded intercooler can help manage the increased heat and keep your engine running efficiently..
TMIC vs. FMIC - When it comes to choosing between a TMIC and FMIC, there are a few factors to consider. TMICs are generally easier to install, retain the stock look, and respond quickly due to their close proximity to the turbo. However, their location under the hood means they can suffer from heat soak in spirited street driving or when you’re at the race track. On the other hand, FMICs are positioned at the front of the car where they have better access to cool air. They are generally larger and offer superior cooling performance, but they may lag slightly in throttle response due to the longer piping and often require more extensive modifications for installation.
Reliability and Durability - Aftermarket intercoolers are typically built with high-performance driving in mind and are often more robust and reliable than their stock counterparts. They can withstand higher boost pressure and are usually more resistant to heat soak, providing consistent performance during spirited or track driving. However, it's important to remember that professional installation is often recommended to ensure proper fitment and operation.
