If you're looking to give your ride a little extra oomph, the Injen RD Series Performance Cold Air Intake (CAI) is a solid choice. I’ve had my hands on this system for a while now, and let me tell you, it’s a game changer for the 2000-2004 Toyota Celica GT. The folks at Injen really put in the work to make sure this intake not only boosts power but also looks sharp under the hood.
So, what's the magic behind this intake? At the core, you've got a mandrel-bent 6061-T6 aluminum air intake tube. This isn’t just any tube; it’s designed to create a smooth, uninterrupted airflow that really makes a difference. It reaches deep into the engine bay, pulling in the coolest, densest air available, which is crucial for performance. Plus, with dyno-proven gains of up to 12 horsepower and 12 lb-ft of torque, you’ll definitely feel the difference when you hit the gas.
One of the standout features is the Injen SuperNano-Web dry air filter. It’s fully serviceable, which means you can clean it and keep it performing at its best. The increased surface area allows for better airflow while still keeping out the dirt and debris that could hurt your engine. If you’re into keeping things clean, you can grab a hydroshield too—part numbers 1035BLK or 1035RED—for that extra layer of protection.
And let’s not forget the sound. This intake gives your engine a deep, throaty growl that you can really appreciate when you’re pushing it hard. It’s not just about the numbers—it’s about the experience, right? Plus, you can choose between a polished finish or a sleek, powder-coated laser black look to match your style.
What’s even better is that this system is made right here in Pomona, California, so you know you’re getting quality craftsmanship. And for peace of mind, Injen backs this kit with a limited lifetime warranty. It’s nice to know they stand behind their product.
In short, if you want to add some serious horsepower to your Celica without the need for additional tuning, the Injen RD CAI is worth considering. Just install it and enjoy the ride.
