Hey there, fellow car enthusiasts! If your engine feels like it's gasping for air and you’re itching for a little extra horsepower, let me tell you about the Injen SP series cold air intake. This isn’t just any intake; it’s a game-changer for your 2017-2018 Honda Civic Si L4-1.5L Turbo. Seriously, if you want to let your engine breathe better, this is the way to go.
Now, Injen isn't just another name in the aftermarket scene. They’ve got the chops to back it up, being the first to ever patent a tuned air intake system. Yep, they hold four patents on their tuning process, which is pretty impressive when you think about it. The SP series packs in a ton of their patented tech, including MegaRam (MR) and Air Fusion technologies. What does that mean for you? It means you’re getting an intake that’s engineered for performance and efficiency.
The heart of this setup is the 6061-T6 aluminum air intake tube. It’s designed to create a smooth, uninterrupted airflow, which is crucial for maximizing power without compromising on safety. You’ll be happy to know that it’s dyno-proven to deliver gains of up to 29 hp and 25 lb-ft of torque. And the best part? You won’t need any additional tuning to make it work. It’s a direct fit, so you can install it and hit the road without any worries.
One of my favorite features is the Injen SuperNano-Web dry air filter. It’s fully serviceable, meaning you can clean it and keep it in top shape for years to come. Plus, it has a larger surface area for better airflow and filtration. And let’s not forget the sound—this intake gives your engine an aggressive, throaty tone that you’ll definitely notice when you hit the gas.
If you’re looking to add a personal touch, Injen offers this intake in multiple finishes, so you can find one that matches your style. And just to give you peace of mind, it comes with a limited lifetime warranty. How cool is that?
Just a heads-up, this intake isn’t CARB exempt, so if you’re in California or have a vehicle registered there, you might want to look elsewhere.
Features:So, if you’re ready to give your Civic Si the boost it deserves, the Injen SP cold air intake is a solid choice. Your engine will thank you!
