Parts for your 2004 Daihatsu Yrv-Manifold gasket

2004 Daihatsu YRV manifold gasket — what it is and why it matters

Technical references confirm the 2004 Daihatsu YRV does use manifold gaskets. The Daihatsu service/repair manual for the K3-VE and K3-VET engines specifies intake manifold removal/installation with a replacement gasket, and exhaust manifold removal/installation with a new gasket. The Daihatsu Electronic Parts Catalogue (YRV M201G/M211G) lists both intake and exhaust manifold gaskets for these engines, and mainstream aftermarket catalogues used in Australia and New Zealand (e.g., AA Gaskets/Permaseal, Nitto, AJUSA) supply direct-fit manifold gaskets for 2004 YRV variants. That makes the part relevant to both naturally aspirated and turbo YRV models.

On the YRV, the manifold gasket’s job is simple but crucial: it seals the mating surfaces between the cylinder head and the intake and exhaust manifolds. On the intake side, a good seal stops unmetered air sneaking in and upsetting fuel trims, idle quality, and fuel economy. On the exhaust side, it prevents hot gas leaks that can tick loudly on cold start, cook nearby components, and lead to dodgy O2 sensor readings. Turbo K3‑VET versions also rely on additional metal gaskets at the turbo/manifold and turbo/downpipe joints to keep boost response crisp and backpressure where it belongs.

There’s no fixed service interval for manifold gaskets on a YRV
