Best Cold Air Intake For 102Mm Throttle Body: 4-Inch Options

#1 · Best Overall

1. PTNHZ Universal 4-Inch Filter

Best for: Standalone 102mm filter buyers.

Why it ranks #1: Its listed 102mm (4-inch) neck directly matches the target inlet size, and the package includes a filter and stainless steel clamp.

A stated 102mm (4-inch) neck size is the PTNHZ filter’s clearest advantage for a matching air inlet. Supplied as an air filter and stainless-steel clamp, it offers a compact, simple component choice for buyers assembling a universal intake setup rather than seeking a complete vehicle-specific system.

The 102mm neck specification directly targets a matching 4-inch inlet, making connection sizing the key selection point for a buyer with that opening. The package lists one filter and one stainless-steel clamp, so it covers the basic filter-clamping step while leaving the rest of the intake arrangement to the installer. PTNHZ describes universal use across vehicles, motorcycles, boats, and racing cars, and states the intended benefits as more airflow, throttle response, and horsepower.

Skip it if you need intake tubing, a heat shield, or a complete vehicle-specific system in the same package.

Choose this for a 102mm inlet project where a filter and clamp are the components you need. Its universal-use description does not supply a full intake layout, so buyers seeking a complete system should look elsewhere.

#2 · Best LS-Swap Kit

2. RiAiCiING LS Swap Intake

Best for: LS swap clearance planners.

Why it ranks #2: The kit targets LS1, LS2, LS3 and several other LS engines, with driver- or passenger-side filter placement for swap clearance.

Driver- or passenger-side filter placement gives this RiAiCiING intake flexibility to work around swap-bay constraints. Its universal design lists compatibility with multiple LS-family engines, while the stated clearance goal is space between the radiator and accessory pulleys—useful priorities when routing an intake in a converted vehicle.

The choice of filter side lets an installer route the intake around available space, and the clearance focus targets the tight area between radiator and accessory pulleys. Compatibility lists LS1, LS2, LS3, LQ4, LQ9, LY6, and 4.8-, 5.3-, 5.7-, and 6.0-liter engines, so it speaks to a range of LS swaps rather than one named vehicle. It supports speed-density setups and round MAF sensors; MAF installations require additional couplers and clamps.

Skip it if you need a complete MAF hookup from the listed kit; it requires additional couplers and clamps for that sensor setup.

This is aimed at LS-swap builders who need filter-side flexibility and clearance around the radiator and accessory pulleys. Check the listed engine and sensor setup against your project; a 102mm throttle-body connection is not specified.

#3 · Oil-Free Filter

3. AEM 21-854C Intake

• Weight: 9.1 lb

Best for: Reusable-filter maintenance planners.

Why it ranks #3: This vehicle-specific system lists low-restriction aluminum tubing, a heat shield, and a washable, reusable oil-free filter.

A washable, reusable oil-free filter gives the AEM 21-854C a clear maintenance distinction. AEM states that the filter can last up to 100,000 miles before cleaning, depending on driving conditions, while the heat shield and edge-trim-lined design address the intake’s placement and surrounding edges.

Low-restriction aluminum tubing is paired with a heat shield, giving the system a defined intake path and a shielded arrangement rather than a filter alone. The oil-free Dryflow filter is washable and reusable, and AEM lists cleaning intervals up to 100,000 miles depending on driving conditions; that can reduce how often maintenance is due, but does not eliminate cleaning. The vehicle-specific fit designation is important: the supplied information does not establish a 102mm throttle-body connection.

Skip it if you need a verified 102mm connection for a universal setup; PTNHZ RACING AIT72 lists a 102mm neck size.

This suits a buyer seeking a vehicle-specific AEM system with reusable, oil-free filtration and a heat shield. Confirm that its application matches the vehicle and throttle-body arrangement; the supplied details do not give a 102mm inlet size.

#4 · Reusable Filter

4. AEM 21-827C Intake

• Weight: 12.4 lb

Best for: Multi-hose AEM system seekers.

Why it ranks #4: Its listed package includes tubing, a heat shield, an adapter, and hoses; the washable oil-free filter is specified for up to 100,000 miles between cleaning.

The AEM 21-827C includes two hoses alongside its intake tube, adapter, and heat shield, giving buyers a more fully itemized system package. Its washable, reusable oil-free filter adds a maintenance option, with cleaning listed up to 100,000 miles depending on driving conditions.

The included adapter and two hoses provide named connection components for the system, while the aluminum tubing is described as low restriction and the heat shield has edge trim. That combination supports a complete vehicle-specific intake arrangement rather than a standalone filter. The oil-free filter is washable and reusable, with cleaning intervals up to 100,000 miles depending on conditions. No supplied specification gives a 102mm throttle-body connection, so this fit detail remains important to resolve.

Skip it if you need a confirmed 102mm neck size; PTNHZ RACING AIT72 explicitly lists a 102mm inlet neck.

This fits buyers seeking an AEM vehicle-specific intake with adapter and hose components included, plus reusable filtration. Match the listed vehicle application before choosing it; the supplied details do not confirm a 102mm throttle-body interface.

#5

5. AEM 21-846C Intake

• Weight: 9.6 lb

Best for: Oil-free filter maintenance seekers.

Why it ranks #5: This vehicle-specific AEM system includes a heat shield and low-restriction aluminum tubing, but the supplied details do not specify a 102mm connection.

The AEM 21-846C pairs low-restriction aluminum tubing with an oil-free, washable filter, giving this vehicle-specific system a clear airflow and upkeep focus. Its filter is listed for cleaning at intervals up to 100,000 miles, depending on driving conditions, rather than as a disposable-only component.

A heat shield and low-restriction aluminum tubing form the listed intake hardware, while the oil-free synthetic filter media is washable and reusable. Together, those features offer an intake path plus a filter that can be cleaned and returned to service. AEM states cleaning may be needed as far out as 100,000 miles depending on conditions, not as a fixed interval. The included fitting and vehicle-specific fit designation do not specify a 102mm throttle-body connection.

Skip it if you require an explicitly listed 102mm inlet; PTNHZ RACING AIT72 gives that neck-size specification.

Consider this AEM system if your vehicle application matches and you value washable oil-free filtration with a heat shield. For a 102mm throttle body, the supplied details do not establish the connection size.

#6

6. AEM 21-855C Intake

Best for: Dual-shield system shoppers.

Why it ranks #6: The listed kit includes two heat shields and a hose, while its vehicle-specific fit does not establish compatibility with a 102mm throttle body.

Two heat shields are included with the AEM 21-855C, a notable hardware distinction for buyers comparing vehicle-specific intake packages. The system also pairs low-restriction aluminum tubing with washable, reusable oil-free filter media, whose cleaning interval is listed up to 100,000 miles depending on conditions.

The two heat shields, hose, and edge trim are listed alongside the intake tube and filter, giving buyers a clear view of the system’s included hardware. Low-restriction aluminum tubing is intended to support airflow, while the oil-free filter can be washed and reused rather than replaced after each service. AEM lists cleaning up to 100,000 miles depending on driving conditions. Its vehicle-specific fit designation does not confirm a 102mm throttle-body connection.

Skip it if you need a stated 102mm neck size for a universal intake build; PTNHZ RACING AIT72 lists one.

This is for buyers whose vehicle matches the AEM application and who want a package listing two heat shields with reusable filtration. Treat 102mm throttle-body compatibility as unconfirmed by the supplied details.

#7

7. AEM 21-862C Intake

• Weight: 8.4 lb

Best for: Tool-ready vehicle-specific installs.

Why it ranks #7: It lists a heat shield, coupler, and aluminum tubing, but provides no 102mm sizing or application details for confirming this throttle-body match.

AEM says the 21-862C can be installed with commonly available tools, giving this vehicle-specific intake a practical installation distinction. It is also described as tuned and dyno-tested to improve acceleration and engine sound, with low-restriction aluminum tubing completing the stated performance-focused setup.

The included intake tube, heat shield, coupler, and edge trim identify key parts of the system, while the commonly available tools note can help buyers plan installation without specialized tooling. AEM describes the system as tuned and dyno-tested for acceleration and engine sound, and its low-restriction tubing supports the airflow-focused layout. The filter’s cleaning interval is listed up to 100,000 miles depending on conditions. Vehicle-specific fit is stated, but a 102mm connection is not.

Skip it if you need an explicit 102mm inlet dimension; PTNHZ RACING AIT72 lists a matching 102mm neck size.

Choose this for a matching vehicle application where tool-accessible installation and the stated acceleration and sound aims matter. Its supplied details do not verify a 102mm throttle-body interface, so that remains a fit boundary.

#8

8. Volant 15153D Intake

Best for: Volant brand-specific shoppers.

Why it ranks #8: The listing identifies a cold-air intake but supplies no inlet diameter, vehicle fitment, or component details to establish suitability for a 102mm setup.

Volant identifies this listing simply as a cold air intake, making the brand and product category its clearest supplied differentiators. The package is listed at 22.2 by 17.2 by 15.2 inches and 12.15 pounds, information that helps buyers assess handling and storage before installation.

The stated package dimensions and 12.15-pound weight give a practical sense of the item’s physical scale when planning to handle or store it. Its included component is identified as a cold air intake, but the supplied details do not establish a 102mm connection or a particular vehicle application. That makes it a limited-information option for shoppers who already recognize the Volant item and can establish the relevant fit through information beyond this listing.

Skip it if you require a listed 102mm neck size or vehicle application; PTNHZ RACING AIT72 specifies a 102mm neck.

This listing suits shoppers seeking the Volant cold air intake by brand and who can independently establish application fit. For a 102mm throttle-body setup, its supplied details leave the connection size unresolved.
