Injen SP1839P SP Short Ram Intake for 2009-2012 Mitsubishi Lancer Ralliart 2.0T

Vehicle Fitment

• 2009-2012 Mitsubishi Lancer Ralliart (L4-2.0L Turbo 4B11T AWC)

Fitment Notes

• Compatible with the Mitsubishi Lancer Ralliart equipped with the 2.0L turbocharged 4B11T four-cylinder engine with All-Wheel Control (AWC) only. Does not fit the standard Lancer, Lancer GTS, or Lancer SE equipped with the naturally aspirated 2.0L or 2.4L engines - those applications use different intake configurations.
• Does not fit the Lancer Evolution (Evo X) - the Evo's intake and airbox layout differs from the Ralliart despite sharing the same engine family. See the appropriate Injen application for the Lancer Evo.
• The SP1839P is a short ram intake that installs in the factory airbox location. For the cold air version for this same vehicle with higher dyno-proven gains, see Injen SP1837P (polished) or SP1837BLK (black) - note that the SP1837 cold air version will not fit vehicles equipped with HID headlights, while the SP1839P short ram does not carry this restriction.
• No tune required. The SP1839P is engineered using Injen's patented MR Technology to maintain safe air/fuel ratios throughout the powerband within the stock ECU calibration, with no check engine lights.
• CARB Exempt - CARB Executive Order D-476-8. Legal for use on vehicles registered in California and all other CARB-compliant states.
• Also available in wrinkle black finish - see Injen SP1839BLK for that option.
• Optional Hydroshield (black): Part #1035BLK - recommended for wet or dusty driving conditions.
• Compatible Injen throttle controller: PT0006B (optional, sold separately).

Features

• Dyno-proven performance gains of up to 15 additional horsepower and 15 lb-ft of torque over the factory airbox, verified on Injen's in-house dynamometer - substantial gains for a bolt-on short ram intake on a turbocharged platform
• 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 4B11T turbo engine's airflow and boost 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 4B11T's boost curve
• 6061-T6 aluminum intake tube provides a smooth, turbulence-free, full-diameter airflow path from the filter to the turbocharger inlet - replacing the factory plastic ducting with a precision-engineered aluminum flow channel
• Short ram / underhood installation places the filter in the factory airbox position - clean, accessible install that is not affected by HID headlight packaging constraints that limit the fitment of the longer cold air SP1837
• High-polish mirror finish on the aluminum tube delivers a premium, show-quality underhood appearance
• 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 turbo induction sound enhancement under throttle - the open-element aluminum design allows the 4B11T's boost and induction characteristics to come through more audibly for a noticeably more spirited character
• Bolt-on installation replacing the factory airbox - 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 SP1839P is an SP Series flagship aluminum short ram intake system engineered specifically for the 2009-2012 Mitsubishi Lancer Ralliart equipped with the 2.0L turbocharged 4B11T engine. It delivers dyno-proven gains of up to 15 horsepower and 15 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 SP1839P is the polished mirror-finish version; the wrinkle black SP1839BLK is also available.

Owners considering Injen's intake options for the Ralliart should be aware of the key difference between the SP1839P and the SP1837P cold air intake for the same vehicle. The SP1837P routes the filter lower in the engine bay for cooler intake air and delivers higher gains of up to 20 HP / 17 lb-ft - but it will not fit Ralliart vehicles equipped with HID headlights due to packaging constraints in that area of the engine bay. The SP1839P short ram installs in the factory airbox location and carries no such restriction, making it the straightforward choice for HID-equipped cars or owners who want a clean, quick installation without routing the intake tube behind the headlight assembly. At +15 HP / +15 lb-ft, the SP1839P still delivers meaningfully greater power than most competing short ram designs for this platform.

Injen's patented MR (MegaRam) Technology is built into the polished tube's stepped internal geometry, individually tuned for the 4B11T's airflow and boost characteristics. The Air Fusion patents further optimize flow dynamics for consistent power delivery through the turbo's boost curve. The SuperNano-Web Dry filter is cleanable with compressed air and never requires re-oiling. Made in Pomona, California and backed by Injen Technology's Limited Lifetime Warranty against defects in material and workmanship for the original purchaser.
