Spark Plug Maintenance tools by Sealey.
These are superior quality tools, precision made from the best materials. We hope you find these additions to our range useful. All prices are subject to VAT at 17.5%
Please note that tool manufacturers classify spark plug spanners by the size of thread rather than the size of the hex nut. For 10mm assume a hex size of 16mm, for 14mm assume a hex of approx. 21mm. Regrettably we cannot send tools to addresses outside the UK due to the high weight and high postage cost.
