1.9CDTi Induction Manifold De-flap kit.
This kit allows you to re-use your original inlet/induction manifold 2.03462.03 (or 2.03462.02) 55210201, 55210202 with the swirl flaps REMOVED, meaning there is no need to replace your existing manifold.
This De-flap kit is designed specifically to work with the Pierburg inlet manifold part number 2.03462.03 55210201, 55210202 (See pic).
This Pierburg inlet manifold is fitted to many Vauxhall (CDTI), Saab (TiD), Fiat (D Multijet) and Alfa Romeo (JTD) 1.9 diesel 150bhp engines.
Please check yours is compatible. Make sure that all the part numbers, shown in the picture, match yours.
This kit consists of:
5 x Taper machined aluminium bushes
Each aluminium bush is machined to a taper, so it will drop into the hole easily to locate, with around half of its length inserted. The second half of the bush is machined to a tight fit that will require the use of a G clamp*, or similar, to press it into place. This creates an incredibly strong seal. BondLoc is also used, giving even more strength than necessary.
Once ‘De-flapped’ the square runner of the manifold will now be free flowing with no swirl flaps.
The flap actuation motor should be left on the vehicle, and connected electrically, but with the lever arm disconnected. This allows the ECU to recognise that the motor is present, and working, and should not cause EML.
Please note, if you have an earlier version of the manifold, this kit can still be used, however the swirl flap holes in earlier versions are smaller in diameter, so they would need to be machined out in order to accept the blanking plugs included in this kit.
