Description
Is your Bentley Arnage misfiring, running rough, or showing a cylinder 1 misfire fault code? A worn or damaged ignition lead is one of the most common causes of a single cylinder misfire on the Arnage V8 engine — and this genuine OEM ignition lead part number 07V905409 is the correct replacement for cylinder 1 on all Arnage R, RL and T models from 2002 onwards.
The ignition lead — also called a spark plug wire — carries the high voltage electrical pulse from the ignition coil to the spark plug. Over time the insulation degrades, the internal conductor corrodes, and the resistance increases — causing weak or misfiring spark. On the Arnage V8 this typically shows as a rough idle, hesitation under acceleration, or a check engine light with a P0301 cylinder 1 misfire code.
Symptoms of a failing cylinder 1 ignition lead: Check engine light with fault code P0301 cylinder 1 misfire, rough idle especially when cold, hesitation or stumble during acceleration, slight drop in fuel economy, engine vibration at idle.
Important: This listing is for the cylinder 1 ignition lead only — part number 07V905409. The Arnage V8 uses 8 ignition leads in total, one per cylinder.

Important fitment note: This lead fits Arnage R, RL and T models from VIN 08323 onwards — 2002 to 2010. It does NOT fit the Bentley Arnage Green Label or early Arnage models. VIN verification is essential before ordering.
