If you're looking to give your 2003-2007 Honda Accord a little extra kick, check out the RD Series Performance cold air intake from Injen Technology. These folks really know their stuff. They've poured hours into designing and testing this system to ensure it not only boosts horsepower but also looks pretty slick under the hood.
At the heart of this intake is a mandrel-bent 6061-T6 aluminum tube. What does that mean for you? It means a smooth, uninterrupted airflow that helps your engine breathe better. This tube dives deep into the engine bay to grab the coolest, densest air it can find, which is key for performance. Plus, it keeps your air-fuel ratios in check throughout the powerband, so no need for any extra tuning—just bolt it on and go!
And let’s talk about the filter. The Injen SuperNano-Web dry air filter is fully serviceable and has a larger surface area, which means it allows for better airflow while keeping dirt and debris at bay. You’re not just getting power; you’re getting quality filtration too. And yes, you’ll definitely feel that power increase, especially when you hit the gas. It has this aggressive, throaty sound that really makes your Accord stand out from the crowd.
Want to customize your look? You can choose between a polished finish or a sleek powder-coated laser black. Either way, it’s going to give your engine bay a nice touch. Plus, Injen backs this product with a limited lifetime warranty, so you know they stand behind their work.
