Tecnical Enquiries

The answers to most enquiries can be found within the references above. However, if you require some personal assistance we will be happy to make a suggestion or answer your enquiry to the best of our ability. We have a wealth of knowledge, gathered over the last 9 years as the original UK online specialist spark plug and glow plug retailer.

Please note that for modified vehicles or a non standard part, your engine tuner or mechanic should be best placed to advise you of a suitable replacement part. We can usually suggest a replacement part but we are unable to actively recommend a non standard part for any vehicle.
