Z16LEH Exhaust Manifold for K04/K06/K16 Turbo

This high flow Z16LEH cast exhaust manifold is manufactured in the same way as an Original Equipment (OE) manifold would be fabricated. The result is a turbocharger assembly for the 1.6 Turbo engine (Z16LEx/A16LEx/B16LEx) that is capable of flowing more air, thus producing more boost and therefore more power and torque.

In fact our Z16LEH manifold has a 20% larger exhaust housing than the Z20LEH manifold and the wastegate aperture is also 20% bigger, so the Z16LEH manifold will offer much greater flow than the equivalent Z20LEH turbo manifold.

It has been designed for the Vauxhall/Opel 1.6 Turbo Z16LEx/A16LEx/B16LEx engines - Z16LET, Z16LEL, Z16LER, A16LET, A16LER, B16LER as fitted to Corsa D VXR/OPC and SRi Turbo, Corsa E VXR, Astra H Turbo, Meriva VXR/OPC and Insignia 1.6 Turbo to allow the fitment of the core turbo charger from the Astra VXR Z20LEH engine.

It fits directly to the head as an OE 1.6 manifold will and the front pipe location is in the same location as the original - no exhaust adapter piece is required, so a standard pre-cat or a pre-cat replacement pipe will bolt straight on with no modification whatsoever. So this really is direct fit. Look closely at the images, and whilst this looks like a Z20LEH turbo, you will see the designation Z16LEH on the cast manifold for the 1.6 application.

Provision has been made for the addition of an EGT probe into the manifold if required.

Available with or without the K04/K06/K16 turbo unit. Upgrade 360 degree bearing and seal upgrade also available.
