Cold Air Intake Kits & Parts

What Does a Cold Air Intake Do?

A cold air intake replaces your factory airbox and filter to feed the engine cooler, less restricted air. Cooler air is denser than warm underhood air, so it carries more oxygen for combustion and helps the engine make more power. Most kits relocate the filter away from engine heat, toward the front corner of the engine bay or beside the radiator.

A typical system includes a mandrel-bent intake tube, a washable high-flow filter, and a heat shield or sealed airbox to block hot air. Ready to compare every option?

How Much Horsepower Does a Cold Air Intake Add?

Horsepower gains from a cold air intake are real but modest, and they vary by vehicle, engine, and supporting mods. Gains tend to be largest on trucks and V8s with restrictive factory airboxes, and smaller on engines that already breathe well. Because results depend on your exact setup, check the details listed on each part before you buy.

Beyond peak numbers, most drivers notice quicker throttle response and a deeper intake sound. For a closer look at real-world results, read our guide on how much horsepower a cold air intake can add to your vehicle.

Top Cold Air Intake Brands

JEGS stocks cold air intakes from established induction brands, each with its own filter technology and fitment focus. Popular choices include:

• K&N cold air intakes: reusable oiled cotton-gauze filters engineered for high airflow and long service life.
• Spectre air intake systems: aluminum tubes, heat shields, and high-flow filters for custom and direct-fit setups.
• AEM Induction cold air systems: sealed intakes with DryFlow oil-free or cotton-gauze filters, many of them CARB-exempt.
• Volant closed-box intakes: Cross-Link polyethylene airboxes and direct-fit kits built to seal out hot air.

Each brand publishes vehicle-specific fitment, so filter by your year, make, and model to see the kits that bolt onto your car or truck.

How to Choose the Right Cold Air Intake for Your Vehicle

Start by confirming your vehicle's year, make, model, and engine, since fitment drives most of the decision. Direct-fit kits are engineered for one vehicle and bolt to factory mounting points, while universal kits let you build a custom setup around your engine. Weigh these factors before buying:

• Fitment: pick a direct-fit kit for a bolt-on install, or a universal kit for custom routing.
• Filter type: oiled cotton-gauze filters flow strongly and are washable, while dry synthetic filters clean without re-oiling.
• Enclosure: open-element filters pull in more sound, while closed-box and short-ram designs balance airflow against heat shielding.
• Emissions: check the CARB status listed on each part if you live in California or a state that adopts its standards.
• Budget: universal kits and filters often start near $50, vehicle-specific kits typically run $100 to $400, and high-performance systems can exceed $400.

Cold Air Intake Installation and Maintenance

Most cold air intake kits are a bolt-on install that uses basic hand tools and factory mounting points. Work with the engine cool, disconnect the battery, and follow the included instructions to position the filter away from heat and secure every clamp.

Washable filters need periodic service: clean the element when it looks dirty and re-oil oiled cotton-gauze types before reinstalling. Keep a spare filter on hand so your intake keeps flowing while one dries.
