PRODUCT DETAILS
HKS SUPER SQV4 Suction Return Kit FL5 Civic Type R | 71002-AH004

The HKS Suction Return Kit (part 71002-AH004) converts the HKS Super SQV IV kit on the 2023+ Honda Civic Type R (FL5, K20C) to a recirculating setup. Vented air is routed back into the intake, so the valve works like the factory air bypass valve. The sharp venting sound gets quieter and the intake sound becomes more noticeable.

Fitment

  • Honda Civic Type R FL5, 2023 and newer (HKS lists 09/2022-on production)
  • For use with the HKS Super SQV IV kit for FL5 (71008-KH012 or 71008-KH012B)

Specifications

  • Manufacturer part number: 71002-AH004
  • Function: recirculates blow off air into the intake (closed loop)
  • Average install time: about 1 hour (HKS)

What's in the box

  • Recirculation hose
  • Hardware

Good to know

This kit does not include the blow off valve. If it is installed after the SSQV4 kit is already on the car, a separate gasket is required.

FAQ

Why add a return kit?

Recirculating the vented air keeps metered air in the intake, like the stock bypass valve, and makes the setup quieter. HKS notes that venting to atmosphere does not pass Japanese vehicle inspection.

Does it work with other blow off valves?

HKS lists it for the Super SQV IV kit for the FL5.

How long does shipping take?

Delivery times vary by part because many items ship directly from the manufacturer or distributor. Message us before ordering and we'll confirm current lead time.

Can I return it?

Yes. Returns are accepted within 30 days of delivery. The customer pays return shipping, and a restocking fee of up to 20% may apply.

WHY WE CARRY THIS

We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.

  • Fitment-first mindset — no “universal” roulette
  • Brand reputation matters — we favor proven manufacturing
  • Support that actually responds with real answers
WHAT TO EXPECT

This is the clean path: correct fitment, clean install, and results that match the intent.

  • Install-ready experience with correct mounting where provided
  • Finish that holds up to real driving, not just photos
  • Selections on this page drive the exact fitment shipped

TRUST, BUILT INTO THE PROCESS.

Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”

Fitment checked

We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.

Brand discipline

Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.

Real support

If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
