What is aFe POWER and what performance products does it make?

aFe POWER (Advanced FLOW Engineering) is an aftermarket performance parts brand that designs and manufactures intake, exhaust, filtration, and related upgrade components for cars and trucks. According to the company, its product line covers over 3,000 applications, with products tested and manufactured in Corona, California. If you're shopping for a bolt-on performance upgrade for a specific vehicle, aFe is one of the brands you'll likely compare — but the deciding factor is almost always whether a part is listed for your exact year, make, model, and engine.

What aFe POWER makes

The site organizes its catalog into these core categories:

• Cold air intake systems — the brand's best-known product type, sold under several lines
• Air filters — replacement and upgrade filters, including dry-media options
• Exhaust systems — including stainless steel cat-back systems
• Electronics — such as power modules
• Intercoolers and charge pipes
• Suspension
• Headers
• Accessories — for example, a wall-mounted storage rack and a bull bar

Product lines you'll see in the catalog

aFe groups products under named lines. From the current listings, these include:

Filter media designations also appear in product names, such as Pro 5R and D2 Dura-Dry, which distinguish different filter constructions within the same intake or replacement-filter family.

How aFe says its products are tested

The company states that its products are dyno tested on an in-house DynoJet, and that airflow products are additionally flow bench tested. This is a manufacturer claim about its own process — useful context for comparing brands, but not a substitute for the vehicle-specific fitment and performance data listed on each product page.

What to check before buying

Because aFe parts are vehicle-specific, matching your vehicle to the product is the step that matters most:

1. Confirm year, make, model, and engine. Listings are written this way — for example, a part may be listed for a specific model year range and a specific engine displacement and induction type (naturally aspirated vs. turbocharged).
2. Check the product line and stage. Stage-1, Stage-2, and Super Stock System designations indicate different levels of intake configuration, so two intakes for the same vehicle are not interchangeable.
3. Note the filter media. Pro 5R and D2 Dura-Dry are different media types; replacement filters are sold by dimension as well as by application.
4. Verify the part number. Each listing carries a distinct part number, and color or finish variants (for example, black vs. red charge pipes) have separate numbers.

Where prices come from

Listings on the site show a price alongside an MSRP. For example, current new-product listings show prices below the stated MSRP, with both figures displayed. Prices are shown per product and vary widely by category — replacement filters sit at the low end, while exhaust systems and catalytic converters sit much higher. Check the individual product page for the current figure rather than relying on any single example.

The short version

aFe POWER is a California-based aftermarket brand covering intakes, filters, exhaust, electronics, intercoolers, suspension, and headers, with a catalog of over 3,000 applications and in-house dyno and flow bench testing. The practical way to use that catalog is to start from your exact vehicle and engine, then pick the product line and stage that matches what you're trying to change.
