Direct Route Inlet Hose. A pipe to remove the heavy transfer pipe fitted to Astra G/H and Zafira A/B 2.0 petrol turbos. The pipe mimics the path first found and seen on the Cavalier & Calibra Turbo. It can be used with a cone filter such as the AEM Dryflow, K&N Apollo, Viper or flowmaster Induction - style kit, or as shown with the 1.9 CDTi MK5 Astra airbox.The hose kit consists of an inlet hose with integral moulded breather spigot, a breather hose and breather hose joiner. The inlet hose is 4 ply silicone for strength with a properly shaped fluoro lined breather hose.
Will fit Astra H and Zafira B VXR models.
Also suitable for Astra G, Zafira A, Astra H (Non VXR) and Zafira B (Non VXR) 2.0 Turbo models. Can be used with the factory 70mm air flow meter or upgrade to the 80mm air flow meter.
When being fitted to Astra G and Zafira A 2.0 Turbo you can either choose the option to use the factory 70mm air flow meter or upgrade to an 80mm airflow meter. If upgrading to the 80mm air flow meter ecu will require a remap to be re-calibrated for the 80mm air flow meter because to 0-5v scale is different for the 80mm air flow meter.
Fitting the Direct Route airbox will require the air flow meter wiring to be lengthened.
The 1.9 airbox also requires modification to allow the 80mm air flow meter to fit. The DIY kit can be supplied with an unmodified airbox or a kit which includes an aluminium joiner that need to be bonded into the box once the outlet has been opened out, hose clip and rubber OE joiner for air flow meter to airbox.
We can supply an airbox modified ready to fit, or for self modification.
