The Exhaust Systems Australia TOYOTA-HILUX-PRADO-4-0L-V6-STEEL-HEADER-GASKET-2-X-REQ is a steel header gasket listed to fit the Toyota Hilux and Prado with the 4.0L V6, with two (2 x) required per fitment.
What does a steel header gasket do?
A header gasket seals the joint between the cylinder head's exhaust ports and the extractor or manifold flange, holding that seal through constant heat cycling. Steel is used here so it lasts under exhaust temperatures. It's a service and fitment part, not a performance one — its job is simply to stop exhaust leaking where the manifold bolts to the head of the 4.0L V6.
Why does it list two per vehicle?
The listing marks it "2 x req", meaning two gaskets are needed for one fitment. That's typical of a V6 with a bank of exhaust ports on each side of the engine, so each side gets its own gasket. When you order, account for the pair rather than a single, and we'll confirm the count against your specific head and manifold arrangement.
Will it suit my Hilux or Prado?
It's listed to fit the Toyota Hilux and Prado running the 4.0L V6 — the same petrol six across both. Because a header gasket only seals correctly if the port pattern matches exactly, confirm your specific head and manifold with the workshop before ordering, and renew it whenever the extractors or manifold come off the V6.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits header gaskets like this as part of extractor and manifold work across the Illawarra. We clean the faces, check the flange for distortion and torque the fasteners evenly so the seal holds. At a recommended retail of $23 each it's usually fitted alongside a larger job. Send your details and we'll confirm it matches your 4.0L V6.

Common questions
How many do I need?
Two. The listing is marked "2 x req" because the 4.0L V6 has a bank of ports each side. We confirm the count at fitment.
Does it suit both the Hilux and Prado?
Yes. Both are listed with the 4.0L V6 this gasket is made for.
Is it a performance part?
No. It's a steel header gasket — a sealing part fitted when the extractors or manifold come off the V6.
