If you're looking to give your 2018-2019 Lexus GS300 2.0L Turbo a little extra oomph, the HPS Black 4-Ply Reinforced High Temp Silicone Post MAF Air Intake Hose is worth considering. This isn’t just any aftermarket part; it’s a solid upgrade that replaces that restrictive stock intake tube with something that really opens things up.
What I love about this hose is its construction. Made from high-temp reinforced silicone, it’s built to withstand the heat without breaking a sweat. Unlike the OEM rubber hose, which can really choke off airflow, this bad boy increases the overall intake volume significantly. It starts out with a generous 3.5-inch (89mm) inside diameter, tapering down to 60mm at the exit. This design ensures that air flows smoothly into your engine, which is crucial for performance.
And let’s talk performance. You can expect a nice bump in power with dyno-proven gains of +6.2 horsepower and +7.3 ft-lbs of torque, all without needing to mess around with re-tuning your setup. Plus, it keeps your air/fuel ratio safe, so you won’t have to worry about any engine trouble. The best part? No check engine light issues here—just pure, unadulterated driving pleasure.
Installation is a breeze, too. You can get this installed in about 30 minutes and it requires no modifications to your car. HPS even includes industrial-grade 100% stainless steel T-bolt clamps to make the process that much easier. Just a few simple tools and you’re good to go.
So if you’re ready to enhance your Lexus experience, this silicone intake hose is a solid choice. It fits a range of models, including the GS200t, GS300, IS200t, IS300, RC200t, and RC300, so there’s a good chance it’ll work for your setup.
