The performance of a vehicle can often be enhanced with aftermarket parts, and one of the most debated upgrades is the intercooler. In this article, we will explore whether aftermarket intercoolers are worth the investment by testing the Mishimoto vsGarrett intercooler on the Toyota IS300.
Understanding Intercoolers
An intercooler is a heat exchanger that cools the air compressed by the turbocharger or supercharger before it enters the engine. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which can lead to improved performance. Upgrading to an aftermarket intercooler can provide significant benefits, but it’s essential to understand how they work and what advantages they may offer.
Why Upgrade to an Aftermarket Intercooler?
There are several reasons why car enthusiasts consider upgrading to an aftermarket intercooler:
- Improved Cooling Efficiency: Aftermarket intercoolers often feature larger cores and better materials, which can significantly improve cooling efficiency.
- Increased Power Potential: By allowing for cooler, denser air to enter the engine, an aftermarket intercooler can help maximize the power output.
- Better Reliability: High-performance intercoolers are designed to withstand higher pressures and temperatures, leading to increased reliability.
- Enhanced Aesthetics: Many aftermarket options come with a sleek design that can improve the overall look of the engine bay.
Introducing the Mishimoto vsGarrett Intercooler

- Reconnect the piping, ensuring all connections are tight.
- Reinstall the front bumper and check for any clearance issues.
Performance Testing
After installation, performance testing is crucial to determine the effectiveness of the aftermarket intercooler. We conducted a series of tests to compare the stock intercooler with the Mishimoto vsGarrett intercooler.
Testing Methodology
Our testing methodology included:
- Baseline dyno runs with the stock intercooler.
- Dyno runs after installing the Mishimoto intercooler.
- Temperature readings before and after the intercooler.
- Real-world driving tests to assess performance improvements.
Results
The results of our testing showed significant improvements:
- Power Increase: The Mishimoto intercooler provided a power increase of approximately 15-20 horsepower.
- Temperature Reduction: Intake temperatures were reduced by an average of 10-15 degrees Fahrenheit under load.
- Throttle Response: Improved throttle response was noted, especially during high RPMs.
Conclusion: Are Aftermarket Intercoolers Worth It?
Based on our testing of the Mishimoto vsGarrett intercooler on the IS300, it is evident that aftermarket intercoolers can provide substantial benefits. The improvements in power, temperature management, and overall performance make them a worthy investment for enthusiasts looking to enhance their vehicles. While the initial cost may be higher than stock options, the long-term gains in performance and reliability justify the expenditure.
