If you're looking to give your 2003-2004 Toyota Matrix XR 1.8L a serious boost, check out the HPS Polish cold air intake kit. This isn't just another shiny part; it’s designed to help your engine breathe better by relocating the air filter outside the engine compartment. Why does that matter? Cooler air means denser air, and denser air packs more oxygen into the combustion chamber, which translates to more power and torque. You’ll feel the difference in throttle response too—this thing really wakes up your ride.

One of the cool things about this kit is its versatility. It can be set up as a long ram intake or converted into a short ram intake, depending on your preference. The lightweight, mandrel-bent aluminum alloy tubing replaces that bulky stock air box, optimizing airflow and keeping things cool. Plus, you won’t have to worry about tuning after installation, which is a relief for those who don’t want to mess with their ECU.

Installation is pretty straightforward, thanks to the clear manual with step-by-step pictures. Just a heads-up, you will need to remove the front bumper during the install, but no major modifications are required. Once it’s in, you’ll appreciate the HPS signature reinforced silicone hoses and industrial-grade stainless steel T-bolt clamps—these are built to last, even if you push your car to the limits.

And let’s not forget about the air filter itself. The HPS Performance Air Filter is washable and reusable, so you can keep it clean without shelling out for replacements. It’s made right here in the U.S. and comes with a one-year limited warranty. Just keep in mind, this kit isn’t CARB compliant, so if you’re in California, you might want to consider that.

In terms of fitment, this kit is specifically designed for:

• Pontiac Vibe 1.8L (2003-2004)
• Toyota Corolla 1.8L (2003-2004)
• Toyota Matrix XR 1.8L (2003-2004)

So, if you’re ready to give your Matrix a little extra oomph, the HPS cold air intake kit is a solid choice. It’s straightforward to install, effective, and built to handle whatever you throw at it.
