If you own a MK3 Ford Focus RS, you already know it’s a blast on the highway and a real contender on the track. But if you’re looking to squeeze out even more power from that 2.3L Turbo engine, you might have noticed that the stock intercooler just doesn’t cut it once you start cranking up the boost. That’s where the Injen FM9003i Front Mount Intercooler comes into play.
This isn’t just any intercooler; it's designed specifically for your Focus RS. The factory tube-and-fin setup can struggle with heat soak, especially when you start tuning or adding bolt-ons. The FM9003i features a bar-and-plate design that increases core volume by over 25%, which means it can handle the heat way better than stock. You can expect an average 35% reduction in charge air temperatures, so your engine stays happy and responsive.
What does that mean for you? Well, when your charge air temps stay close to ambient, you won’t see the factory ECU pulling timing due to excessive heat. This intercooler lets you keep the power flowing consistently, whether you’re cruising to work or pushing it hard on the track. We’re talking about gains of up to 14 horsepower and 15 lb-ft of torque, all while retaining factory boost pressure. It’s a solid upgrade for both stock and modified setups.
Installation is a breeze, taking about an hour. The FM9003i bolts right into place using all the factory mounting points, and it comes with all the necessary hardware to make your life easier. Just remember, it doesn’t come with new piping, so you’ll want to stick with your stock intercooler piping for this one.
Built with precision cast end tanks and CNC-machined aluminum flanges, this intercooler is all about purposeful airflow management. Plus, it sports a slick silver finish that looks pretty sharp under the hood. And if you’re worried about durability, Injen backs this product with a Lifetime Warranty, so you can hit the track with confidence.
