aFe Jeep Wrangler/Gladiator 3.6L Rapid 5R

Rapid Induction for the specified Jeep 3.6L engine

aFe 52-10008R is a Rapid Induction intake for the specified Jeep Wrangler JL and Gladiator JT 3.6L V6 configurations. One oiled Pro 5R filter seats in an 18-gauge wrinkle-black steel shield on the original lower airbox, while the XLPE tube replaces the original tube between the filter and throttle body.

Key Features

• One nominal 7-inch-tall conical Pro 5R filter with five layers of pre-oiled cotton gauze; washable, reusable and re-oiled after correct cleaning/drying.
• 18-gauge steel top-mounted shield retains the lower half of the original airbox and reuses its four upper screws.
• Full XLPE tube with slotted mounting tabs reuses the original shroud screws, two mounting grommets and spacers.
• Transfers the original IAT into a supplied grommet and plastic bung; reconnects the original CCV quick-connect to the new NPT fitting.
• Silicone bellows and two size-048 coupling clamps; selected filter flange clamp is also secured during installation.
• Selected-media flow: 345 CFM at 7 inches H2O versus 250 CFM stock, approximately 38% higher.

Fitment

For the 3.6L V6 Wrangler JL and Gladiator JT configurations named below. The illustrated manual covers Wrangler 2018–2021 and Gladiator 2020–2021; the current manufacturer headline broadly lists both through 2026. Individual exact-part retailer application entries support the additional named years shown, including 2020–2023 Gladiator Mojave/Texas Trail/Willys-related coverage and Wrangler Rubicon through 2024. Other later named trims and years still require confirmation of the actual engine, mounting, sensor and CCV layout; absence from this table is not a physical-incompatibility claim. Preserve the original lower airbox and compare later vehicle revisions to the illustrated installation. This does not establish 2.0L, plug-in 4xe, 3.0L diesel or 6.4L fitment, and the shared broad headline does not make Gladiator available before its 2020 model-year start.

Verify 52-10008R against the actual engine, sensor and vent connections, mounting locations and applicable emissions requirements before ordering.

Specifications

What's Included

The shared manual lists a separate Pro DRY S alternative, but this R kit supplies the Pro 5R oiled element only. Reuse the original lower airbox, four upper-airbox screws, two radiator-shroud screws, original IAT, CCV quick-connect, and both original tube grommets and spacers. The filter-flange clamp is used in the illustrated procedure; the BOM does not provide its separate service code. Do not apply the newer 2.0L Rapid kit’s no-sensor-transfer procedure to this full-tube 3.6L system.

The selected 22-91201R is a nominal 7-inch conical Pro 5R element with five pre-oiled cotton-gauze layers. Clean and dry it using aFe’s procedure, then recharge with the specified blue filter oil. It is not the dry alternative listed in the shared manual.

Keep the lower factory airbox. The new steel shield mounts to it using the four original upper-airbox screws; the new filter locks into the shield’s retention groove.

Yes. Transfer the original IAT into the new grommet and plastic bung, then reconnect its electrical harness. Reconnect the original CCV quick-connect to the supplied NPT vent fitting.

No. The manual specifically says exposed threads are normal and warns against overtightening. It provides no numerical torque or separate thread-sealant requirement; do not force the hex flush or borrow another kit’s procedure.

Transfer both original tube grommets and spacers in their original orientation and reuse both shroud screws. Install the silicone bellows with its two supplied coupling clamps and secure the selected filter flange clamp after alignment.

The exact manufacturer page advertises up to 9 hp and 9 lb-ft. Its linked 2020 Wrangler JL 3.6L chart shows 9.07 hp and 9.49 lb-ft differences at about 5,000 rpm; differences between separate maximum values are 5.40 hp and 9.80 lb-ft. The baseline notes an aFe cat-back while the intake run notes OE exhaust, so this is not a controlled intake-only comparison. Both runs list OE wheels and tires, third gear, a 1,500-rpm start, 20% preload, red fans and a silver fan. These test results do not guarantee gains on every vehicle. The separate bench-flow chart shows selected Pro 5R flow of 345 CFM versus 250 CFM stock at 7 inches H2O, approximately 38% higher; its 330-CFM Pro DRY S alternative is not the supplied oiled filter.

The current exact manufacturer page and manual state non-CARB-exempt status and California purchase/use restrictions. Check seated bellows, all three intake clamps, original screws, sensor/CCV connections and clearance; recheck after 100–200 miles. No numerical torque is supplied.

Installation Instructions

Verify aFe 52-10008R. Work only on a cool engine and retain the factory hardware. Release the three Christmas-tree ties attached to the intake tube, disconnect the IAT electrical plug and original CCV quick-connect, remove the four upper-airbox screws and two radiator-shroud tube screws, loosen both original tube clamps and remove the factory tube and upper airbox. Keep the LOWER factory airbox in place. Remove the factory filter and mount the Rapid steel shield to the lower airbox using the four original screws. Install the 29-inch trim around the upper edge, cutting only the trim as needed for fit. Install the supplied NPT vent fitting in the new XLPE tube: exposed threads are normal, and the manual warns not to overtighten. Fit the new rubber sensor grommet and plastic temperature-sensor bung, using the specified light penetrating oil only if needed to seat the bung. Transfer both original tube mounting grommets and spacers, keeping the spacers in their original orientation. Fully seat the selected filter flange in the shield’s retention groove, loosely fit its clamp, and fit the silicone bellows and two coupling clamps. Install the tube between the filter and throttle body, reuse the two original shroud screws, and tighten all three intake clamps with the bellows fully seated. Reconnect the original CCV quick-connect, transfer the original IAT sensor to the new bung and reconnect its harness. Check clearance, routing, secure mounts and every connection, then recheck bolts, clamps and connectors after 100–200 miles. No numerical clamp torque, fitting torque or separate thread-sealant requirement is given; do not borrow such details from another kit.

Important Disclosures

The current exact manufacturer page and the illustrated manual state that this kit is not CARB exempt and is unavailable for purchase in California or use on a California-registered vehicle. Exemptions for other intake part numbers do not transfer. The steel shield retains the original lower airbox but is open at the filter; it is not a sealed waterproof enclosure or a certification of greater fording depth. The current manufacturer’s broader model-year headline and older illustrated procedure differ; confirm actual mounting and connections for later revisions rather than treating model names alone as proof. The exact manufacturer page advertises up to 9 hp and 9 lb-ft. Its linked 2020 Wrangler JL 3.6L chart shows 9.07 hp and 9.49 lb-ft differences at about 5,000 rpm; differences between separate maximum values are 5.40 hp and 9.80 lb-ft. The baseline notes an aFe cat-back while the intake run notes OE exhaust, so this is not a controlled intake-only comparison. Both runs list OE wheels and tires, third gear, a 1,500-rpm start, 20% preload, red fans and a silver fan. These test results do not guarantee gains on every vehicle. The separate bench-flow chart shows selected Pro 5R flow of 345 CFM versus 250 CFM stock at 7 inches H2O, approximately 38% higher; its 330-CFM Pro DRY S alternative is not the supplied oiled filter.
