Injen SP1675BLK SP Cold Air Intake for 2008-2012 Honda Accord 2.4L Black

Vehicle Fitment

• 2008-2012 Honda Accord (LX, LX-S, EX, EX-L | Sedan & Coupe | L4-2.4L K24Z3)

Fitment Notes

• Compatible with both the 8th-generation Accord Sedan (CP chassis) and Coupe (CS chassis) equipped with the 2.4L four-cylinder K24Z3 engine. Does not fit the V6-3.5L Accord - that application requires a different intake system.
• No tune required. The SP1675BLK is engineered using Injen's patented MR Technology to maintain safe air/fuel ratios throughout the powerband within the stock ECU calibration.
• CARB Exempt - CARB Executive Order D-476-8. Legal for use on vehicles registered in California and all other CARB-compliant states.
• This intake is also available in a polished mirror finish - see Injen SP1675P for that option.
• Optional Hydroshield (black): Part #1033BLK - fits filter X-1014. Optional Hydroshield (red): Part #1033RED - recommended for wet or dusty driving conditions.

Features

• Dyno-proven performance gains of up to 11 additional horsepower and 9 lb-ft of torque over the factory airbox, verified on Injen's in-house dynamometer
• Injen's patented MR (MegaRam) Technology (Patents 7,359,795 and 7,669,571) is built into the stepped internal geometry of the aluminum tube, individually tuned for the K24Z3's airflow characteristics to maximize power output while maintaining safe air/fuel ratios and preventing check engine lights
• Air Fusion technology (Patent 7,721,669) further optimizes the airflow dynamics for consistent power delivery across the K24Z3's full RPM range
• Cold air intake design - the tube is routed to collect cooler, denser air from within the engine bay for improved combustion efficiency over the factory airbox position
• 6061-T6 aluminum intake tube provides a smooth, turbulence-free airflow path from the filter to the throttle body - replacing the factory plastic ducting with a flow-optimized aluminum channel
• Laser black wrinkle powdercoat finish delivers a bold, durable underhood appearance with long-term resistance to heat, scuffs, and corrosion
• Fully serviceable SuperNano-Web Dry air filter provides greater filtration surface area and lower restriction than the factory paper element - cleanable with compressed air and reusable indefinitely
• Aggressive K24Z3 induction sound enhancement under acceleration - the open-element design lets the 2.4L's naturally aspirated intake note come through clearly at high RPM
• Bolt-on installation - no cutting, drilling, or permanent modification required
• Made in Pomona, California, USA
• Protected by Injen Technology's Limited Lifetime Warranty to the original purchaser against defects in material and workmanship

Product Description

The Injen SP1675BLK is an SP Series flagship aluminum cold air intake system engineered specifically for the 2008-2012 Honda Accord equipped with the 2.4L K24Z3 four-cylinder engine - covering both the Sedan (CP chassis) and Coupe (CS chassis) body styles. It delivers dyno-proven gains of up to 11 horsepower and 9 lb-ft of torque with no tune required and no check engine lights, and is fully CARB-legal under Executive Order D-476-8. The SP1675BLK is the laser black wrinkle powdercoat version; the polished mirror-finish SP1675P is also available.

The SP Series is Injen's flagship aluminum intake line, and the power gains the SP1675BLK delivers on the K24Z3 come directly from Injen's patented MR (MegaRam) Technology - a stepped internal tube geometry that is individually dyno-tuned for the 2.4L Accord's specific airflow characteristics. This is not a generic tube with a filter; the diameter transitions within the tube are engineered to control airflow velocity and volume at the points where the K24Z3 most benefits from improved intake flow, while the Air Fusion patents further optimize the flow dynamics for consistent power delivery across the RPM range. The cold air tube routing positions the filter in a cooler part of the engine bay than the factory airbox, providing a real intake air temperature advantage that contributes to the power gain.

The laser black wrinkle powdercoat finish is heat-resistant and highly durable, maintaining its appearance over years of underhood exposure. The SuperNano-Web Dry filter is cleanable with compressed air and never requires re-oiling. Installation is bolt-on to the factory mounting location with no permanent modification required. Made in Pomona, California and backed by Injen Technology's Limited Lifetime Warranty against defects in material and workmanship for the original purchaser.
