How to Install a High Volume Intake on the Integra Type S

Quick answer

On a 2024+ Acura Integra Type S DE5, a high volume intake install is a bolt-on job you can finish in an afternoon with basic hand tools. The PRL Motorsports carbon fiber high volume intake system is CARB approved under EO D-878-8 and requires no ECU calibration, so you can install it, verify the MAF housing is seated and sealed, and drive.

Before you start: confirm the DE5 fitment and clear the work area

The PRL Motorsports 2024+ Acura Integra Type S DE5 Matte Carbon Fiber High Volume Intake System fits all Integra Type-S DE5 models, including RHD and international variants, so you do not need to worry about chassis variants. Work on a cold engine, disconnect the negative battery terminal if you are uncomfortable around the MAF sensor connector, and lay out the intake box, filter, MAF housing, and hardware on a clean towel so nothing rolls into the engine bay.

Remove the factory airbox and inlet plumbing

Loosen the hose clamp at the throttle body side of the factory intake tube, unclip the airbox lid, and lift the factory airbox out of its grommets. Disconnect the MAF sensor connector by releasing its locking tab rather than pulling on the wires. Keep the factory fasteners in a labeled bag; if you plan to return the car to stock later, this is the step that makes that easy.

Trial-fit the carbon fiber intake and MAF housing

Set the carbon fiber intake into the engine bay and check clearance around the strut tower, hood line, and any wiring harness before you tighten anything. The 4-inch cone filter and billet two-piece MAF housing with velocity stack are the parts that determine final alignment, so position them loosely first. A dry-fit catches interference while you can still shift parts by hand instead of forcing a clamp.

Tighten clamps and torque hardware in the correct order

Once alignment is confirmed, tighten the MAF housing fasteners first, then the intake tube clamps, then the airbox or bracket mounting points. Snug clamps by hand and finish with a driver; over-tightening is the most common cause of cracked plastic and deformed silicone couplers. PRL does not publish a torque figure for this kit, so use the standard practice of firm-snug plus a quarter turn on small hardware and stop there.

Reconnect the MAF sensor and confirm no ECU calibration is needed

Plug the MAF sensor back in until the locking tab clicks, then double-check that the connector is fully seated. Because this intake is designed to work with the factory calibration, no ECU calibration is required. Start the car and let it idle for a minute; a steady idle with no check engine light is your first confirmation that the MAF housing is sealed and the sensor is reading correctly.

Intake install steps and checkpoints

1. 1. Cool the engine and disconnect the battery: Work on a cold engine so you are not leaning over hot exhaust or intake components, and disconnect the negative terminal before unplugging the MAF sensor. Checkpoint: engine bay is cool to the touch and the battery is isolated.
2. 2. Remove the factory airbox and MAF connector: Release the MAF locking tab with your fingers instead of tugging the harness, then lift the airbox out of its grommets and bag the factory hardware. Mistake to avoid: pulling the MAF wires can damage the connector pins.
3. 3. Dry-fit the carbon fiber intake and MAF housing: Set the intake, billet two-piece MAF housing, and 4-inch cone filter in place loosely and check clearance at the strut tower, hood, and wiring. Checkpoint: no contact points before you tighten anything.
4. 4. Tighten in sequence and stop at firm-snug: Secure the MAF housing first, then the tube clamps, then the mounting points, using firm-snug plus a quarter turn on small hardware. Mistake to avoid: over-tightening clamps cracks plastic and deforms couplers.
5. 5. Reconnect the MAF and start the car: Push the MAF connector in until it clicks, then start the engine and let it idle. No ECU calibration is required for this intake. Checkpoint: steady idle and no check engine light.
6. 6. Road-test and re-check clamps: Drive normally for a few miles, then park and re-snug the clamps and mounting hardware once the intake has heat-cycled. Next step: re-check after the first drive to catch any settling.
