Product description

Magnuson’s Toyota 4Runner MP90 Supercharger System is designed exclusively for  2003 - 2009 model years, equipped with the 4.0L 1GR-FE V6 engine. Engineered to be robust, system incorporates High-thermal transfer intercooler for maximum aircharge cooling, yielding super low inlet air temps for consistent power from startup to shut down and to abate belt slip even under extreme conditions, the MP90 boasts a custom engineered supercharger belt-drive system for worry-free driving both on and off-road.

This system was developed to be a direct bolt on kit with minimal downtime, and straightforward installation. An enthusiast with basic tools can install the system in a weekend, or about a day for an experienced installer. The MP90 also looks and fits like OEM, almost like it belongs there. With no cutting or welding, it’s also easily reverted to stock. The supercharger itself is maintenance free- pre-filled and sealed, nothing to check or top off for the lifetime of the engine.

With Toyota reliability and Magnuson power, what are you waiting for?

FAQs

Does the MP90 Supercharger Tuner Kit fit both automatic and manual 2003-2009 4Runners?

Yes, this MP90 kit is designed for 2003-2009 Toyota 4Runner vehicles with the 1GR-FE 4.0L V6 in either automatic or manual configuration. It’s engineered as a complete bolt-on package for straightforward integration.

Does this MP90 kit include tuning and calibration?

This is a tuner kit, so calibration is not included. It’s designed for builders working with a tuner who will supply the correct calibration for the vehicle configuration.

What makes the MP90 kit feel stock-like at cruise but strong under throttle?

The integrated bypass strategy unloads the supercharger at idle and part throttle to keep cruising smooth and efficient. When you tip into the throttle, boost comes on immediately and predictably.

How does the MP90 kit support consistent performance for off-road or long pulls?

The kit uses a high-thermal transfer intercooler strategy to keep charge-air cooling efficient under load. A custom-engineered belt-drive system is used to support stable drive behavior under demanding conditions.
