If you're looking to swap out that stock intake tube in your 2018-2019 Lexus GS300 2.0L Turbo, let me tell you about the HPS Blue 4-Ply Reinforced High Temp Silicone Post MAF Air Intake Hose. This isn’t just any aftermarket part; it’s a solid upgrade that really makes a difference in how your engine breathes.

The factory intake tube is pretty restrictive, but this HPS silicone piece opens things up. With a hefty 3.5-inch (89mm) inside diameter at the primary section—compared to the stock's 3-1/8 inch (80mm)—you get a noticeable boost in intake volume. It tapers down to 60mm at the exit, which helps keep airflow smooth and efficient. What does that mean for you? Better performance without needing to mess with your engine tuning. We're talking about a dyno-proven gain of +6.2 Whp and +7.3 Ft/lbs of torque, all while maintaining a safe air/fuel ratio. Plus, it doesn’t trigger any check engine lights, so you can drive worry-free.

Installation is pretty straightforward, taking about 30 minutes tops. You won’t need to make any modifications, which is a huge plus if you’re not into cutting and welding. The kit even comes with high-quality stainless steel T-bolt clamps to make the process easier. Just pop it in and you’re good to go.

Here’s a quick rundown of the features:

• Crafted from HPS Performance’s race-proven high-temperature reinforced silicone.
• Replaces that restrictive OEM rubber intake hose, boosting airflow and reducing heat soak.
• Delivers solid performance gains without any re-tuning needed.
• No check engine light issues here.
• Easy installation in about 30 minutes.
• Includes durable, industrial-grade stainless steel T-bolt clamps.

And just to be clear on fitment, this bad boy works with:

• Lexus GS200t 2.0L Turbo (2016-2017)
• Lexus IS200t 2.0L Turbo (2016-2017)
• Lexus RC200t 2.0L Turbo (2016-2017)

• Lexus IS300 2.0L Turbo (2018-2024)
