THE CARB-LEGAL COLD AIR

Yes, Injen is widely respected in the induction and intakes space — Injen is California-based, CARB-EO certified, and one of the few intake brands engineering intake-tube geometry on an in-house chassis dyno. On MOTORMIA, 1,319 Injen parts span cold air intakes, short ram intakes, and intake hardware, with 6,000+ active member builds running Injen components. For most performance buyers, Injen is considered worth the price premium for its combination of street manners and durability under load.

Injen offers fitment across a wide range of platforms. The most-installed Injen fitments on MOTORMIA are: Mitsubishi Lancer, Mazda Mazda6, Scion TC, Hyundai Veloster, and Jeep Wrangler. To confirm exact compatibility for your specific make, model, year, and submodel, use the fitment selector at the top of any Injen product page — the catalog cross-references Injen's part numbers against verified factory specs.

Both. Injen's SP Short Ram Intake lines are engineered for street use — MR Technology (Mega Ram) tube geometry, dyno-tuned for OE drivability, and 50-state legal options. The PowerFlow Cold Air Intake and Evolution lines are track-focused, with Evolution series with oversized filter housings and race-only tubing for forced-induction applications, and remain street-legal but are optimized for repeated heavy use. Most MOTORMIA members running Injen daily choose the street line. Each product page tags the intended use so you can match the part to how you actually drive.

Injen and K&N are both top-tier induction and intakes brands. Injen is California-based dyno-developed intake specialist with Lifetime warranty, while K&N has the broadest fitment catalog with their oiled cotton filter media. On MOTORMIA, Injen parts average $— across 1,319 SKUs. The decision usually comes down to budget, brand preference, and which product line has a direct fit for your specific chassis.

A typical Injen install takes 1–1.5 hours with basic hand tools and 30 minutes to seat the supplied filter properly. Each product page lists torque specs, required tools, and any vehicle-specific gotchas. If you've done similar work before, a Injen install is a weekend job. If this is your first time, a professional shop install is a safe choice for parts that affect braking, steering, or fuel-system pressure.

Yes. Most Injen parts on MOTORMIA are eligible for our standard 30-day return policy provided they're unused, uninstalled, and in original packaging. Exceptions are special-order items (flagged with a "Special Order" badge on the product page) and any part that shows installation marks. The trust box on each product page shows the exact return eligibility for that SKU. Injen's manufacturer warranty (Lifetime) is processed through MOTORMIA on your behalf.
