If you’re looking to give your 2003-2004 Lexus GX470 a serious boost, the HPS Polish Performance Shortram Air Intake is a solid choice. I’ve had my hands on this kit, and let me tell you, it’s a game changer for that 4.7L V8 engine. The 3.5" mandrel-bent aluminum tubing really opens up airflow, making a noticeable difference in throttle response. We're talking about a dyno-proven gain of +6.5 Whp and +6.1 Ft/lbs of torque—pretty impressive for a simple upgrade.

One thing I appreciate about this kit is the heavy-duty powder-coated steel heat shield. It does a fantastic job of keeping engine heat at bay, which means cooler air for better performance. Installation? It’s a breeze. You won’t need to worry about tuning or triggering that pesky CEL light. Just follow the clear instructions in the manual, and you’re set—no modifications required.

The HPS setup comes with everything you need: reinforced silicone hoses that can handle the heat, and industrial-grade stainless steel T-bolt clamps that ensure a tight fit even when you’re pushing the limits on the road. The air filter is a standout as well—made right here in the USA, it’s designed for optimal airflow without compromising on filtration. And the best part? It’s washable and reusable, so you won’t be shelling out cash for replacements every few months.

Just keep in mind, this kit isn’t CARB compliant, so if you’re in a strict emissions state, you might want to check that out. But if you’re just looking to enhance your driving experience, the HPS Polish Performance Air Intake is worth considering.
