Can you remember the time you bought your first weekend warrior? You were still keeping tabs with your budget very closely. Your car was a capable runner despite its engine being naturally aspirated. But over time, your skills began to improve. Before you know it, keeping it stock didn't make the cut anymore. So you considered the most practical solutions to boost your car's power without feeling that you just survived a highway robbery? One of the first practical solutions to increase your car's horsepower is installing an aftermarket intake system. To see how much gain this modification can do to your car, we got an AEM intake hardware kit and installed it to our Subaru STI.
Features of the components included in the kit
- Mandrel-bent aluminum intake pipe
- DryFlow air filter assembly: Non-woven synthetic air filter material, rubber top, and tapered conical filter
- Silicone couplers: High heat and pressure tolerance
- Hose clamps: High-quality stainless steel and double wound
- Washers, bolts, nuts, flange
- We were able to perform the installation in our garage. We didn't have to ask for additional hands from another shop. If you have some knowledge on installing minor aftermarket modifications, then we believe that this phase will not be an issue to you. Besides, AEM has provided a step by step guide complete with photos in the internet.
- After installation, we drove the Subaru to a track. As we made our way through the highway, we felt increased oomph from the engine. The turbo spool also sounded as if it recovered from colds. Before running on the track, we placed the car on the dyno to see how much power the intake kit added. We noted about 10% increase in horsepower. We were convinced that it was ready for the track.
- We brought two STIs for our test. The one we modified and another that we left bone stock. The improved performance was evident. Throughout the test, the modified STI made the other one eat dust. But we think the drivers also had some influence on how big the margin was. So we can safely say that the stock STI could have kept a closer distance if a better driver was behind the wheel.
- Unfortunately, this aftermarket intake kit for the Subaru STI is not street legal in California. Should you be persistent in having it installed in your vehicle while in that state, you're better off building it as a track warrior. Since we wanted to evaluate road and track performance, we decided to execute the installation and testing of the AEM intake hardware kit in another state.
The AEM intake hardware kits can be a practical solution to answer your speed craving. It can add extra power without requiring you to spend too much on installation and troubleshooting. If you are resolute in having this modification, do your research well, and look for the parts that are applicable to your vehicle.
