Cold Air Intakes

A cold air intake replaces the factory airbox with a high-flow filter and tube that pulls cooler air from outside the engine bay. Cold air is denser, which means more oxygen per gulp — and more oxygen means more power. It's typically the very first mod people do because it's easy, affordable, and you can actually hear the difference.

1. COLD AIR INTAKES (CAI)

What It Does

Replaces the restrictive factory air box with a larger-diameter intake tube that pulls cooler, denser air from outside the engine bay. Cooler air is denser, which means more oxygen molecules per cubic foot = better combustion = more power.

HP Gains by Engine

Engine Best Brands HP Gain Torque Gain
5.7L R/T HEMI aFe, JLT, K&N, BBK +8–17 HP +10–20 lb-ft
6.4L Scat Pack HEMI aFe, JLT, Mopar +15–18 HP +15–22 lb-ft
6.2L Hellcat aFe Carbon Fiber +25–37 HP +22–36 lb-ft

Key Brands & Products

  • aFe Power: Momentum GT, Magnum FORCE Stage-2. Known for rigorous dyno testing. Carbon Fiber option for Hellcat is premium.
  • JLT Performance: Popular series 2 CAI — strong mid-range torque focus.
  • K&N: Typhoon system — well-known brand, easy install, good filter longevity.
  • BBK Performance: Budget-friendly, bolt-on in ~30 min, no extra hardware needed.
  • Mopar: OEM-quality, maintains warranty, less aggressive gains.
  • Corsa: Carbon fiber intake option for 6.2L Hellcat.

Install Notes

  • Most CAIs are 30–60 minute installs, no special tools.
  • Some may trigger a check engine light due to MAF sensor sensitivity — tune may be needed.
  • Sealed (enclosed) intakes maintain cooler air temps vs. open filters that can heat-soak.
  • Pairs best with tune to maximize gains — tune alone on stock intake is significant, CAI + tune is better.

Site UX Recommendations

  • Display "Does this require a tune?" clearly on each listing (most do NOT require one for basic install).
  • Show HP ranges by engine size prominently.
  • "Best First Mod" badge — CAI is the consensus #1 beginner purchase.
  • Sound clips: Some intakes have a distinctive induction growl under hard acceleration.
