Injen Cold Air Intake for 09-13 Honda Fit

Injen SP Cold Air Intake - 2009-2013 Honda Fit

Your Fit's got a 1.5-liter engine making 117 hp at the crank. It's slow. The stock airbox is restrictive. The intake tube's got bends and ridges that choke airflow. The engine's starving for air and you're feeling it every time you try to merge onto the highway. Injen's SP cold air intake replaces the entire stock airbox and intake tube with a 6061-T6 aluminum tube and a high-flow SuperNano-Web dry filter. You're getting smoother airflow, more cold air, and more power. Injen's dyno'd this intake at 8 hp and 7 lb-ft of torque. That's on a car that's only making 117 hp stock. You're getting a 7% power increase just from letting the engine breathe. The intake also sounds way better than stock. You're on the throttle and you're hearing the engine pull air instead of the muffled wheeze the stock airbox makes. This is what you install when you're done being embarrassed at stoplights and you're ready to actually feel something when you hit the gas.

Here's Why the Stock Intake Is Choking Your Engine

The stock Fit airbox is designed to be quiet. Honda doesn't want you to hear the engine working. They want the car to be appliance-quiet so it appeals to the widest possible market. The problem is the baffles and sound deadening that make it quiet also restrict airflow. The stock intake tube's got bends that create turbulence. The filter surface area is small. The intake pulls hot air from the engine bay instead of cold air from outside the car. Hot air's less dense than cold air. Less dense air means less oxygen. Less oxygen means less power. Injen's cold air intake fixes all of that. The aluminum tube's smooth and straight. No bends. No ridges. No turbulence. The filter's got way more surface area than the stock paper filter. The intake pulls cold air from in front of the radiator instead of hot air from the engine bay. Cold air's more dense. More oxygen. More power. The engine's not working as hard to pull the air it needs. You're getting more power and better throttle response.

MR Technology and Air Fusion - Injen's Patented Tuning Process

Injen's not just slapping a tube and a filter together and calling it an intake. They're the world's first company to actually tune intake systems. They hold four patents on the intake tuning process. MR Technology (patents 7,359,795 and 7,669,571) is Injen's MegaRam technology that uses specific tube diameters and lengths to create pressure waves that force more air into the engine at specific RPM ranges. Air Fusion (patent 7,721,669) is Injen's process for optimizing the air velocity and turbulence at the filter to maximize airflow without sacrificing filtration. None of this is marketing hype. It's actual engineering. Injen's dyno testing every intake they build to verify the power gains and to make sure the air/fuel ratio stays safe. You're not leaning out the engine. You're not causing knock. You're just getting more airflow and the ECU's compensating correctly. No tune required. Bolt it on and drive it.

SuperNano-Web Dry Filter - More Flow, Better Filtration

Injen's SuperNano-Web filter is a dry filter. That means you're not oiling it like a K&N. Dry filters are easier to maintain. When it gets dirty, you wash it with soap and water, let it dry, and reinstall it. No oil. No mess. The SuperNano-Web material's got microscopic fibers that trap dirt particles while still flowing way more air than a stock paper filter. More surface area means more flow and longer service intervals. The filter's cleanable and reusable. You're not buying a new filter every year like you would with a paper filter. Injen sells replacement filters (part number X-1010-BB) if you want a spare or if you manage to damage the filter. They also sell hydroshields (part numbers 1035BLK and 1035RED) if you're worried about water ingestion. The hydroshield's a pre-filter that keeps water and large debris out of the main filter. Most people don't need it but it's there if you want it.

Polished or Black Finish - Pick What Looks Good

Injen offers this intake in polished aluminum or black. Polished is the classic hot rod look. Shiny aluminum in the engine bay. It looks good. It shows off the welds. Black is the stealth look. It blends in. It doesn't draw as much attention. Both finishes use the same tube, the same filter, and the same engineering. You're getting the same power gains regardless of which finish you pick. Pick whatever looks better to you. If you want to show off the intake, go polished. If you want it to blend in, go black. The performance is identical.

CARB Legal and Lifetime Warranty

This intake's CARB legal with EO number D-476-8. That means it's legal in California and it won't cause you to fail emissions. If you're in California or any state that follows CARB rules, you're good. Injen backs this intake with a limited lifetime warranty. If it fails, they replace it. That's how confident they are that this intake's not going to break. It's made in Pomona, California. It's not some cheap offshore intake that's going to crack or corrode. It's a quality piece that's going to last as long as you own the car.
