How to find the right Automotive Performance Ram Air Kit AI guide

What the AI looks for in Automotive Performance Ram Air Kit

Street legality: For street use in California and CARB-following states, the kit needs a CARB Executive Order number for your exact vehicle and engine. Intake changes affect emissions, and kits without an EO can fail inspection.
MAF housing calibration: Choose a vehicle-specific kit engineered for your MAF sensor, or plan on a tune if the tube diameter differs from stock. A different tube diameter changes how the sensor reads airflow, which can cause lean or rich codes and drivability problems.
Sealed airbox vs. open element: Prefer a sealed box or heat shield that draws from outside the engine bay over an open filter sitting in engine heat. Hot engine-bay air reduces any gain and can make performance worse than stock.
Filter media: Oiled cotton needs careful re-oiling. Dry synthetic media avoids the risk of oil on the MAF. Over-oiled filters are a known cause of MAF sensor contamination.
Water ingestion risk: Avoid low-mounted filters on vehicles that see deep water or heavy rain unless you fit a bypass valve or pre-filter. Low intakes can pull in water and hydrolock the engine.

K&N: Large range of vehicle-specific intakes, with many listings showing CARB EO status.
AEM: Cold air and short ram intakes, with dry-media options on many kits.
aFe Power: Wide truck and car intake coverage with oiled and dry filter options.
Airaid: Intake kits with airbox and intake-tube designs for trucks and SUVs.
Injen: Performance intake kits with tuned tube designs for many cars.
S&B: Sealed-box intakes, particularly for diesel trucks.

On most stock modern engines the gain is modest. Bigger gains usually come on turbocharged engines or alongside a tune.
