HKS Super Power Flow Intake - Honda Fit GD (07-08)

If you've got a 2007-2008 Honda Fit GD3 and you're looking for more intake sound and throttle response from the L15A, the HKS Super Power Flow replaces your stock airbox with an open-element pod filter that breathes significantly more air. This isn't a cold air intake. It's an exposed filter that sits in the engine bay and pulls air from a larger surface area than your restrictive factory box. You'll hear it, you'll feel the improved response above 5,000 RPM, and your engine bay looks better without a big plastic airbox taking up space.

How the Super Power Flow Works

The Super Power Flow is HKS's signature intake filter design, and the engineering behind it is more involved than a generic cone filter on a pipe. The defining feature is the Super Lip Funnel, a bell-shaped intake profile that maximizes the filter's effective surface area within a limited space. This parabolic shape accelerates incoming air and creates a smooth velocity profile across the entire filter face, reducing turbulence as air enters the intake tract.

The filter itself is a 3-layer dry-type polyurethane element (the green one) on a Hyper Stealth frame with 16 streamlined inner support ribs. The aluminum back plate with black alumite anodizing provides rigidity and a clean look. There's also a plastic sealing ring at the base that prevents unfiltered air from bypassing the element. If you prefer an oiled filter for higher filtration in dusty conditions, HKS also makes a red 2-layer wet-type replacement element that fits the same frame.

HKS specifically notes that throttle response and acceleration improve most noticeably from 5,000 RPM to redline on the L15A. That's the range where the stock airbox is most restrictive, and where you'll actually feel the difference on a small-displacement NA engine like this. Don't expect big gains down low. The L15A makes its power at the top of the rev range, and that's where this intake helps.

HKS Super Power Flow Fit Fitment

This fitment is for the USDM 2007-2008 Fit with the L15A 1.5-liter engine. The same part number also covers JDM GD1/GD2 (L13A) models, but those aren't relevant for most Hybrid Racing customers. This does not fit the 2009+ 2nd gen Fit (GE chassis) or the 2015+ 3rd gen Fit (GK chassis).

What to Know Before You Buy

Installation is a bolt-on job. You're removing the stock airbox and MAF sensor housing, then mounting the Super Power Flow assembly in its place with the included adapter hardware. No cutting or drilling. The kit includes everything you need.

Since you're removing the enclosed airbox and replacing it with an exposed filter, you are now breathing engine bay air, not air ducted from outside the engine compartment. On a hot day in traffic, intake air temperatures will be higher than stock. That's the trade-off with any pod filter. You're gaining airflow volume and throttle response at the expense of air temperature control. On a 1.5-liter NA engine this isn't a major performance concern, but it's worth understanding what you're getting.

HKS recommends switching to a higher heat range spark plug after installing this intake, particularly if you drive hard or do any track days. The increased airflow changes the combustion characteristics slightly. They also note that some cars may benefit from an ECU reset after installation to let the air/fuel maps relearn with the new intake.

The dry-type green filter element should be replaced every 6 to 12 months depending on driving conditions. Replacement elements are inexpensive and available in green (dry, standard), red (wet/oiled, higher filtration), and yellow. Don't skip filter changes. An open element in the engine bay collects dirt faster than a sealed airbox.

This intake is not CARB compliant and cannot be legally sold or used on street-driven vehicles in California or other states that follow CARB emissions standards. It's intended for off-road or competition use in those jurisdictions.
