The cause of an irregular misfire or a stumble under load may be due to a failed component of the ignition system.

This service kit includes everything required to freshen up the ignition system on your Alloytec V6.

Unfortunately, lifting the intake manifold is necessary to access the spark plugs and coil packs but this kit has you covered by including a high quality inlet gasket too which, given the age of the car, will mostly likely need to be replaced anyways.

The coils in this kit come with a 3 year/100,000km parts only warranty.

Specifications:

• Gap setting (spark plug): 1.1mm

Contents:
