  • The Bosch Super 4 operates on the state-of-the-art air-cushion-spark principle and is the first spark plug to feature four thin ground electrodes with one pointed, silver-plated center electrode.

    This combination is unique in the world and has decisive benefits. The ignition spark always chooses the best path for reliable ignition according to the engine load. The Bosch Super 4 does more than a conventional spark plug. In all situations, throughout its service life.

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
